Do-it-yourself water pump: 13 homemade pump designs

Water at their summer cottage is required not only by the owners to comply with sanitary and hygienic standards. It is necessary for watering plants, caring for the territory and pets, refreshing and swimming in the hot summer. Agree that it is difficult to lift the entire required volume from the source manually with buckets.

However, there is a way to alleviate the difficult fate of summer residents - this is a homemade water pump. Even if you don’t have the funds to buy pumping equipment, you can become the happy owner of a useful technical device. To build it, sometimes literally just the power of thought is enough.

We have collected and systematized for you valuable information about making almost free homemade products. The models presented for consideration were tested in practice and deservedly received recognition from the owners. A thorough description of the manufacturing technology is supplemented with diagrams, photographs and video materials.

Design #2 - manual pump with direct spout

A very simple device for pumping water from a barrel or a shaft well. The advantages of this design: speed of assembly, low cost.

Required parts:

PVC pipe d.50mm – 1 pc.;
PVC coupling d.50mm – 1 piece;
PPR pipe d.24mm – 1 pc.;
PPR branch no. 24 – 1 piece;
PVC plug d.50mm – 2 pcs.;
piece of rubber, diameter 50mm, thickness 3-4mm – 1 piece;
check valve 15mm – 1 piece;
empty silicone bottle 330ml – 1 piece;
tightening screw clamp – 1 piece;
screw-nut or rivet – 1 piece;
union nut no. 15 – 1 pc.

We begin the assembly of the entire structure with the manufacture of a check valve.

Construction of a check valve. We prepare a check valve from a Ø 50mm plug. We drill several holes around the perimeter of the plug Ø 5-6mm. In the center we drill a hole of suitable diameter for a screw-nut pair or rivet.

On the inside of the plug we place a rubber disk Ø 50mm. The disc should not rub against the walls of the plug, but should cover all drilled holes. We tighten it in the center with a screw-nut or rivet; a screw will not work. If difficulties arise with materials or manufacturing, you can replace it with a factory-ready check valve.

What a factory-made check valve used to operate a pumping station is is described in detail in the article we recommend.

Preparing the pump sleeve. The length of the sleeve should be commensurate with the depth of the well or container with water. We cut the PVC sewer pipe Ø 50mm to the required length, from the narrow end. We insert the newly made valve into the pipe socket. For reliability, we fasten it on both sides with self-tapping screws.

For the second end we prepare a plug with a pre-drilled hole Ø 25mm. This hole in the plug is made according to the diameter of the PPR pipe Ø 24. Great precision is not required, the plug serves as a sliding support.

Piston assembly procedure. Cut off the spout of an empty silicone container. Next, you need to heat the balloon and insert the sleeve into the PVC so that the diameter of the balloon exactly matches the diameter of the sleeve. Place the silicone can on the valve from the reverse side of the arrow (the arrow on the check valve shows the direction of water movement).

We cut off the excess balloon. We secure it with a union nut no. 15.

Pump rod design. The length of the rod should be 50-60 cm greater than the length of the sleeve. You need to heat one end of the rod and insert a check valve. The arrow on the check valve should point towards the inside of the stem. Until the pipe has completely cooled down, we tighten it with a screw clamp.

Final assembly of the pump. We insert the rod into the sleeve and attach a plug (sliding support) through the coupling on top. To top it off, we attach a 24mm PPR bend to the end of the rod pipe. All you have to do is connect the hose and you can pump water.

The pipe material can be any, and the cross-section is not necessarily round. It is important to select the appropriate piston for the liner

The outlet serves as a support for the hand. For convenience, you can take a tee and plug one side of it.

Option #3 – furnace that creates a pressure difference

The craftsmen whose idea was embodied in this miracle of engineering called their brainchild a “pump furnace.” They, of course, know better, but at the initial stage of its operation this pump looks like a samovar. However, it doesn’t really heat the water, but creates a difference in pressure, due to which its work is carried out.

For such a pump you need:

steel barrel 200 liters;
Primus or blowtorch;
pipe with tap;
mesh nozzle for hose;
rubber hose;
drill.

The pipe with the tap must be cut into the bottom of the barrel. Close the top of the barrel with a screw cap. A hole is pre-drilled in this plug and a rubber hose is inserted into it. The mesh nozzle is needed to close the second end of the hose before it is lowered into the reservoir.

Design #3 - manual pump with side spout

The previous design has one, but significant drawback. The spout moves with the stem. This design is not much more complicated, but much more convenient.

The sleeve needs to be improved. Add a 50mm PVC tee to the design with a 35 degree bend. The tee must be inserted into the upper part of the sleeve. In the rod, near the piston, we drill several large-diameter holes, the main thing is not to overdo it and not to disturb the rigidity of the entire structure.

The piston moving upward pushes the liquid into the outlet pipe. The top cover serves as a support for the piston rod

Now water will begin to pour into the space between the rod and the sleeve. When the piston moves upward, water will begin to flow into the spout.

DIY heat generator (video)

A cavitation heater is quite an interesting and economical way to heat a room. It is easily accessible and can be created independently if desired. To do this, you need to purchase the necessary materials and do everything in accordance with the diagrams. And the effectiveness of the device will not take long to show itself.

For heating rooms or heating liquids, classic devices are often used - heating elements, combustion chambers, filaments, etc. But along with them, devices with a fundamentally different type of effect on the coolant are used. Such devices include a cavitation heat generator, the work of which is to form gas bubbles, due to which heat is released.

Design #4 - piston well pump

This pump design is suitable for wells no more than 8 meters. The operating principle is based on the vacuum created by the piston inside the cylinder. A useful homemade product can be an excellent alternative to factory-made pumping equipment and will help solve the problems of water extraction for servicing a summer cottage.

In such pumps, the top cover is either absent or has a slot-like hole, since the rod is rigidly connected to the handle

Necessary materials:

metal pipe, diameter 100mm, length 1m;
rubber;
piston;
two valves.

The performance of the pump directly depends on the tightness of the entire structure.

You will find a detailed description of the manufacturing process of a piston pump for use in a summer cottage in one of the popular articles on our website.

Step #1: Assembly of the unit sleeve

To make a pump sleeve, you need to pay attention to the inner surface; it must be even and smooth. A good option would be a liner from a truck engine.

From below, a steel bottom needs to be welded to the sleeve along the diameter of the well head. Either a reed valve or a factory valve is installed in the center of the bottom.

A cover is made for the top of the sleeve, although this part is more aesthetic, you can do without it. It is necessary to pay attention to the fact that the hole for the piston rod is made slot-like.

Step #2: Construction of the Pump Piston

For the piston you need to take 2 metal disks. Between them lay not very thick rubber 1 cm, slightly larger in diameter than the disks. Next, we tighten the disks with bolts.

As a result, the rubber disk will be clamped and a sandwich of metal and rubber should be obtained. The idea is to create a rubber rim along the edge of the piston, which will form the necessary piston-liner seal.

All that remains is to install the valve and weld the eye for the stem.

Step #3. Making a petal valve from rubber

The reed valve consists of a rubber disc of not very thick thickness. The disc size should be larger than the inlet holes. A hole is drilled in the center of the rubber. Through this hole and a pressure washer, the rubber disk is secured over the inlet holes.

When sucked, the edges of the rubber rise and water begins to flow. During the reverse stroke, clamping pressure is created: the rubber reliably blocks the inlet holes.

Step #4: Final Assembly and Installation

It is advisable to cut a thread at the head of the well and at the bottom of the pump sleeve. The thread will allow the pump to be easily removed for maintenance and will make the installation sealed.

We install the top cover and attach the handle to the rod. For comfortable work, the end of the handle can be wrapped with electrical tape or rope, laying turn to turn.

If the pump does not pump water, it is necessary to eliminate all leaks, including in connection with the well head (+)

The limitation on the depth of the well is due to the theoretical impossibility of creating a vacuum of more than 1 atmosphere. If the well is deeper, you will have to modify the pump to a deep pump.

Option #4 – black grille for sunny weather

This product will require special devices. Where, for example, do you get a black grille, the hollow tubes of which contain liquefied propane-butane? However, if this part of the problem is solved, the rest does not cause any particular difficulties. So, there is a grille, and it is connected to a rubber bulb (balloon), which is placed in a can. There are two valves in the lid of this can. One valve lets air into the container, and through the other, air with a pressure of 1 atm exits into the air duct.

It’s really better to make the grate black, because black products always heat up more actively under the bright summer sun

This is how the system works. On a sunny day, water the grill with cold water. Propane-butane cools, and the gas vapor pressure decreases. The rubber balloon is compressed, and air enters the can. After the sun dries the grate, the steam will again inflate the bulb, and pressurized air will begin to flow through the valve directly into the pipe. The air plug becomes a kind of piston that expels water through the shower head onto the grate, after which the cycle repeats.

Of course, we are not interested in the process of watering the grate itself, but in the water that collects under it. Experts say that the pump functions perfectly even in winter. Only this time, frosty air is used as a coolant, and the grate is heated by water extracted from the ground.

Design #5 - deep piston pump

The difference from a conventional piston pump is that the pump sleeve must be installed at the depth of the well. In this case, the length of the rod is more than 10 meters.

The sleeve of such a pump can serve as a wellbore, and the role of a spring can be played by a suspended load (+)

There are two ways to solve this problem:

Make the rod from a lighter material, for example, aluminum pipe.
Make a rod from a chain.

The second option requires some explanation. In this case, the rod is not rigid. The bottom of the liner is connected to the bottom of the piston by a return spring.

What is a vortex heat generator

A cavitation vortex heat generator is a simple device that can effectively heat a room while spending a minimum of money. This occurs due to the heating of water during cavitation - the formation of small steam bubbles in places where the liquid pressure decreases, which occurs either during pump operation or during sound vibrations.

A cavitation heater is capable of converting mechanical energy into thermal energy, which is actively used in industry, where heating elements can fail when working with a liquid that has a large temperature difference. Such a cavitator is an alternative for systems operating on solid fuel.

Advantages of vortex cavitation heaters:

Economical heating system;
High heating efficiency;
Availability;
Possibility to assemble with your own hands.

The vortex heat generator should not be located near a living space due to its high noise level

Disadvantages of the device:

When assembling it yourself, it is quite difficult to find materials to create the device;
Too much power for a small room;
Noisy operation;
Considerable dimensions.

Design #6 - American or spiral type

The spiral pump uses the energy of the river flow. To operate, the minimum requirements must be met: depth - at least 30cm, flow speed - at least 1.5 m/s.

Option 1

Necessary materials:

flexible hose d.50mm;
several clamps according to the diameter of the hose;
intake - PVC pipe 150mm;
wheel;
pipe reducer.

The main difficulty in such a pump is the pipe reducer. This can be found in decommissioned sewer trucks or obtained from factory equipment.

For greater efficiency, an impeller is attached to the pump

The flexible hose is attached to the wheel in a spiral using clamps. An intake made of PVC pipe 150mm is connected to one end. The second end of the hose is put on the pipe reducer.

Water is taken in by the water intake and moves in a spiral, creating the necessary pressure in the system. The lifting height depends on the flow speed and the immersion depth of the intake.

Option 2

Necessary materials:

flexible hose d.12mm (5);
plastic barrel d.50cm, length 90cm (7);
polystyrene foam (4);
impeller (3);
sleeve coupling (2);

We cut an intake hole in the bottom of the barrel. Inside the barrel, it is necessary to lay the hose tightly in a spiral and connect it to the sleeve coupling.

Inside the barrel, the hose is laid tightly, pressed against the walls with a strip. The barrel can be metal with foam floats

To impart buoyancy, foam floats must be glued inside the barrel. Finally, screw on the impeller.

For this design option, the drain hose must be 25 mm. in diameter.

Modifications "Diana"

These high-pressure hand pumps for pneumatics are manufactured with two adapters. A distinctive feature of the model can also be called a wide footrest. The handles in this case are made with side pads, and they are rarely washed. The rod in the device is made of aluminum alloy. According to experts, the pressure gauge used is of high quality. In total, it has two measurement scales. The model has a moisture protection system.

The stand is used with a round cross-section. The upper valve of the device is made of cast iron. The maximum overload parameter is 6 microns. The stabilization system is used in the third degree. In total, the model has two sealing sleeves. The device is perfect for PP series cylinders. You can buy a pump of the presented series for 14,400 rubles.

Design #7 - wave energy pump

As the name suggests, such pumps use wave energy. Of course, the waves on the lakes are not that big, but the pump works around the clock and is capable of pumping up to 20 cubic meters per day.

Option 1

Necessary materials:

float;
corrugated pipe;
two valves;
mounting mast.

The float is a pipe, a log, selected depending on the rigidity of the corrugated pipe, experimentally.

Corrugated pipe can be made of plastic or metal. The weight of the log must be selected experimentally

Two valves operating in the same direction are mounted in a corrugated pipe.

As the float moves downwards, the corrugated pipe stretches, resulting in water intake. When the float moves up, the corrugation contracts and pushes the water up. Therefore, the float must be quite heavy and large.

The entire structure is rigidly attached to the mast.

Option 2

This design differs from the first option in that the corrugated pipe is replaced by a brake chamber. This diaphragm-based scheme is very often used in simple DIY water pumps. Such a pump is quite versatile and can receive energy from wind, water, steam, and sun.

The brake chamber should be disassembled and only two holes left for the valves.

Instead of homemade valves, you can use ready-made plumbing valves. The washers must be of sufficient diameter so that the diaphragm does not tear (+)

Manufacturing suitable valves is a separate task.

Necessary materials:

copper or brass tube;
balls of slightly larger diameter - 2 pcs.;
spring;
copper strip or rod;
rubber.

For the inlet valve, cut off the tube and drill it out so that the ball sits tightly on the tube. It is necessary to ensure that the ball does not allow water to pass through. To prevent the ball from falling out, solder a wire or strip on top.

The design of the exhaust valve differs from the intake valve in the presence of a spring. The spring must be installed between the ball and the copper strip.

We cut out a diaphragm from rubber to the size of the brake chamber. To drive the diaphragm, you need to drill a hole in the center and stretch the pin. We insert the valves from the bottom of the brake chamber. For sealing, you can use epoxy glue.

It is better to find non-metal balls for valves, so they will not be subject to corrosion.

Option 3

Based on the design of the two previous options, you can think about building a more advanced model.

It is advisable to choose a log that is dry and not resinous, so it will be lighter, pay attention to the absence of cracks

For this pump it is necessary to drive four stakes (1) into the bottom of the reservoir. Then make a float from a log. You need to make cuts in the log so that it does not rotate when swinging on the waves.

For durability, it is recommended to treat the log with a hot mixture of kerosene and drying oil. It must be done carefully, processed in a water bath: there should be no open flame.

The log travel limiters (3) and (4) are nailed in such a way that the log does not damage the pump rod (5) during maximum movement.

We insulate the VTP

First of all, we put on the casing. To do this, take a sheet of aluminum or stainless steel and cut out a couple of rectangles. It is better to bend them along a pipe that has a larger diameter, so that a cylinder is eventually formed. Next we follow the instructions.

We fasten the halves together using a special lock used to connect water pipes.
We make a couple of covers for the casing, but do not forget that there should be holes in them for connection.
We wrap the device with thermal insulating material.
Place the generator in the housing and close both covers tightly.

There is another way to increase productivity, but for this you need to know how exactly Popov’s miracle device works, the efficiency of which can exceed (not proven and not explained) 100%. You and I already know how it works, so we can proceed directly to improving the generator.

Design #8 - device from a washing machine

Often, parts or even entire units from old things remain on the farm. You can remove a centrifugal pump from a washing machine that is no longer needed. This pump is perfect for pumping water from a depth of up to 2 meters.

Necessary materials:

centrifugal pump from a washing machine;
petal valve from a washing machine or homemade one;
plug, bottle stopper;
hose;
preferably an isolation transformer.

If you use a ready-made valve from a washing machine, it needs to be modified. One hole needs to be plugged, for example using a bottle cap.

Excess pump holes must be plugged. If the case is metal, grounding is required

We connect the petal valve to the hose and lower it into a pit or well. Connect the second end of the hose to the pump. For the system to start working, it is necessary to fill the hose with the valve and the pump itself with water. All that remains is to connect the transformer, and the pump is ready for use.

Purpose

When studying the operating principle of a small treatment plant, one pattern can be noticed. After pumping out wastewater, deposits of silt and other contaminants regularly accumulate on the walls of a cesspool or well. Such an environment promotes the proliferation of harmful and pathogenic microorganisms. Regular removal of sewage from the septic tank makes the sewage system more efficient and creates a favorable sanitary environment.

The use of factory-made equipment will allow you to more effectively cope with the task, but it has a rather high price. In this case, at your summer cottage or in a country house, you can use a homemade pump to pump out the sewage system. Proper assembly of the device will ensure effective removal of wastewater.

Design #9 - water pump from compressor

If you have already drilled a well and have an air compressor, do not rush to purchase a water pump. It will be successfully replaced by a structurally simple airlift device.

Necessary materials:

spout pipe 20-30mm;
air pipe 10-20mm;

The operating principle of the pump is very simple. It is necessary to drill a hole in the spout pipe and place them closer to the bottom. The hole should be 2-2.5 times larger in diameter than the air pipe. All that remains is to insert the air pipe and apply air pressure.

One of the most efficient and simple pumps, does not clog and can be assembled in 5 minutes

The efficiency of such a pump depends on the height of the water level, the depth of the reservoir, and the compressor power (performance). The efficiency is about 70%.

The simplest model

Here are the instructions for “making a pump with your own hands”:

Take a thick-walled plastic bottle and drill a hole in its cap. Its diameter must match the size of the hose.
Make a hole on the side of the bottle too. It is required to pump out air and drain water.
Carefully insert the hose into the cover and secure it with glue.
Screw the resulting structure to the bottle.
Place the free end of the hose in a container of water.
With one hand, squeeze the bottle, squeezing the air out of it, and with the other close the hole on it.
Stop putting pressure on the plastic container - it will begin to return to its original volume, absorbing water. When placing the bottle below a container of water, it will flow by gravity.

Design #10 - gear water machine

The heart of this design is gear pumps for pumping oil from agricultural or truck equipment. The power steering power plant from KrAZ has similar characteristics.

Unit characteristics:

pump working volume - 32 cm3;
maximum pressure - 2.1 Atm;
operating speed - 2400 rpm;
maximum permissible rotation speed – 3600 rpm;
nominal pumped volume – 72 l/min.

If possible, a motor from a washing machine is connected to such a pump. The motor of household appliances has a number of advantages: it runs on a single-phase 220V network and has a starting system (capacitor).

Gear mechanisms can be left- or right-handed, you need to pay attention to the direction of the arrow on the body

Pulleys and a belt may be required to obtain the required RPM. The advantage of a gear pump is that the gears are able to create the necessary suction force even without first filling it with water.

The only note: after operating the pump, to prevent corrosion of the steel gears, it is necessary to let the pump run idle for about 20 minutes.

What is it used for?

Let's give a small example. There are a lot of enterprises in the country that, for one reason or another, cannot afford gas heating: either there is no main line nearby, or something else. Then what remains? Heat with electricity, but the tariffs for this kind of heating can be terrifying. This is where Potapov’s miracle device comes to the rescue. When using it, the energy costs will remain the same, the efficiency, of course, too, since it still won’t be more than a hundred, but the efficiency in financial terms will be from 200% to 300%.

It turns out that the efficiency of the vortex generator is 1.2-1.5.

Design #11 - pump from a bicycle wheel

Productive pump based on two wheels.

Necessary materials:

PVC sewer pipes and outlets;
bicycle wheel;
nylon rope;
small pulley;
several pistons;
mounting rod.

The operating principle of this pump is similar to that of a dragline.

First you need to build a sleeve from a sewer pipe that will be immersed in water. A drain is placed on the top of the sleeve through which water will flow. Next, install a small pulley on the bottom (a wheel rim from a wheelbarrow will do) and a bicycle wheel on top.

We attach a series of pistons along the entire length of the rope, first passing them through the sleeve. The rope should go around the pulley and the bicycle wheel.

The device is very effective, especially if you use a bicycle drive. It will be much easier to twist your legs.

By rotating the bicycle wheel, each piston on the rope captures water and, like an elevator, lifts it upward. The water column pours into the outlet.

Types of devices for pumping water

Physical force alone used to lift water upward is not enough, since the process becomes difficult and labor-intensive. Therefore, mankind has long ago invented many devices that facilitate the rise of liquid from a well or natural reservoir to the surface.

All devices are united by a common operating principle, which is based on the interaction of the valve system.

There are many varieties of hand pumps, but four main types can be distinguished:

piston;
rod deep (varieties of piston);
winged;
membrane

For manufacturing at home, they usually choose the first type if it is necessary to service a well of shallow depth (3-6 m), or the second if it is necessary to lift water from a well from a depth of 10-12 m.

These models are considered to be the most productive, easy to assemble and install, and reliable. The rest have significant shortcomings, the biggest of which is considered to be insufficient productivity.

It is piston devices that have occupied the main niche among factory manual equipment; they are popular among home craftsmen.

Image gallery Photo from The control element of the hand-held device is a long handle that acts like a lever. It controls the rod, which, in turn, moves the fixed piston up/down, due to which water is sucked into the pipe

Factory-made devices consist of cast iron or steel elements. Self-processing of cast iron is almost impossible, so homemade products are welded from steel parts and assembled from plastic pipes

There are several options for connecting, but the most popular is installing a pipe with a check valve: one end of it is lowered into the water, the other is connected to the inlet pipe of the pump. The liquid exits through another pipe located in the upper part

The body of a typical pump has a vertical shape. It is fixed either by landing directly on the casing using flange/coupling connections, or installed on the surface of the earth using support profiles, masking the latter with soil or decor

Method of connecting to a water source

How to install the pump

The advantage of piston column pumps is their ease of assembly and installation. All the parts necessary for the manufacture of the body and dynamic parts can be found on the farm or purchased in addition.

And to connect the elements into a single device, home tools are usually enough: a drill, a circular saw, a hacksaw, pliers, and keys. If necessary, a welding machine can be rented or borrowed from neighbors.

Design #12 - “homemade” for a small stream

This pump can operate on an ultra-low amount of energy. Of course it’s good if there is a river or lake. But what to do if the river becomes very shallow in the summer? A swing type pump will help.

Such a pump allows you to use very small amounts of energy from a small stream.

The main part of the structure is two buckets rigidly connected to each other through blocks (4). It is necessary to make a drainage system from the stream from galvanized steel (3). In order to reduce wear, a piece of plastic is placed under it. The drainage system is rigidly connected by a leash to a rope (5).

Leash 6 is made of rigid wire and the length is calculated so that the drainage system moves to the desired angle

The entire system must be adjusted so that when one bucket is filled, the drainage moves to the second bucket. The energy of the buckets is transmitted through the crank (8) to the pump (10).

Vortex damper

Yes, we will make a device with such a mysterious name - a vortex damper. It will consist of plates arranged lengthwise, placed inside both rings.

Let's see what we need for the job.

Welding.
Turbinka.
Sheet of steel.
Pipe with thick walls.

The pipe should be smaller than the heat generator. We make two rings out of it, about 5 cm each. We cut several strips of the same size from the sheet. Their length should be 1/4 of the length of the device body, and their width should be such that after assembly there is free space inside.

We insert the plate into the vice, hang metal rings on one end of it and weld them to the plate.
We take the plate out of the clamp and turn it the other way. We take the second plate and place it in the rings so that both plates are placed parallel. We fasten all the remaining plates in the same way.
We assemble the vortex generator with our own hands, and install the resulting structure opposite the nozzle.

Note that the scope for improving the device is almost limitless. For example, instead of the above plates, we can use steel wire, first twisting it into a ball. In addition, we can make holes in plates of various sizes. Of course, none of this is mentioned anywhere, but who says you can't use these improvements?

And as a conclusion, here are some practical tips. Firstly, it is advisable to protect all surfaces by painting. Secondly, all internal parts should be made of thick materials, since it (the parts) will constantly be in a fairly aggressive environment. And thirdly, take care of several spare caps that have different hole sizes. In the future, you will select the required diameter in order to achieve maximum performance of the device.

The cavitation heat generator is characterized by good efficiency and compactness. It is rare that an owner does not try to save on heating or the consumption of other benefits, which become more and more expensive every year. To make the heating system of a residential or industrial premises economical, many people resort to various schemes and methods for generating thermal energy. One of the devices suitable for these purposes is a cavitation heat generator.

Design #13 - Shukhov wick pump

The Russian inventor Shukhov became famous for many buildings, including the radio tower in Moscow. Below we will discuss another of his inventions - a water pump.

Pulleys are made composite. The depth of the groove should be slightly less than the swollen rope

The pump uses a special rope to operate. This rope consists of woven cotton threads with a total thickness of 5-6 mm, enclosed in a sheath. The thread is passed through the pulleys.

When movement occurs, the rope gets wet and wraps around the pulleys. The pulley (5) with the help of a spring (4) presses the rope against the pulley (3) with force. The squeezed water flows into the tray (7). Figure “c” shows sections of pulleys (3) and (5), respectively.

To operate the entire system, an electric motor of only 5-10 watts is required. Typically, such engines have 1500 rpm.

To reduce speed and increase force, you can use a worm gear, shown in figure “c”. It is quite possible to make it by hand. To do this, you need to find a suitable gear and make a worm from wire. Small forces on the shaft allow manufacturing inaccuracies.

With your own hands you can assemble not only a pump that pumps water for domestic needs, but also a device that can be successfully used in landscaping a site. The following article will present successful options for homemade fountain pumps.

First start-up and setup of the unit

After installing the pumping sewage equipment and connecting the power supply, the pipeline is installed. Then it is necessary to test the installed system, and also adjust the level at which the float circuit breaker will turn off the unit, protecting it from running dry.

To do this, the septic tank is filled with water. In this case, the liquid level must be at the minimum acceptable level for this equipment. After this, we continue filling the tank until the mark at which the sensor is triggered and the pumping equipment starts.

Testing the device allows you to check its performance and the correct installation of the entire sewerage system. If the slightest problems are detected, they can be quickly and painlessly eliminated at this stage. After successful testing, the receiving well is hermetically sealed. Now you can safely operate the sewer system and be confident in the uninterrupted and reliable operation of the pumping equipment.
