In the article you will find instructions for assembling original pump models, which you can make yourself without specific skills and knowledge. The cost of the above models is minimal, and sometimes they can be completely assembled from scrap materials and household waste.

A water pump is an almost essential thing in a suburban household. Manual and mechanized pumps are also used for pumping other types of liquids – fuel, solvents, oils, etc. The opportunity to purchase an expensive reliable pump is not always available, and cheap models break down, as a rule, at the most inopportune moment. We will consider the options for creating pumps from improvised materials and parts that can be found in every workshop, and their market value is simply negligible in comparison with a new factory product..

Option No. 1. Water pump for overflowing water

The primitive design for pumping water, which can be collected in 10 minutes, will serve as a handy tool for gardening. This is especially convenient when you need to repeatedly collect water from the barrel with buckets. In fact, this is a check valve attached to a tube with a branch.

For manufacturing, you will need a tube, a hose and several necks from plastic bottles assembled.

Working process:

1. Remove the gasket from the cork and cut it 2 mm less than the diameter of the cork, leaving the 3 mm segment intact.
2. We drill a 10 mm hole in the center of the cover.
3. We install the petal in the lid and screw in the cut neck. It will press the remaining segment.
4. We insert the valve into the stem tube and put on a “skirt” from a cut plastic bottle.
5. We put on the discharge hose from the opposite end.

This device is operated by several clicks along the axis of the stem when the intake part with the valve is immersed in water. Further, the liquid will go by gravity as long as there is a difference in levels. Then the water can be raised by immersing the stem in the barrel.

This is the only “negative value” product. When you create it, you will not only spend nothing (except for time), but also use household waste with benefit.

Option number 2. Simple do-it-yourself hand pump

In this manual, we will give an example of a manual pumping system, which can be taken as a basis for creating a stationary pumping station on a well or well..

A – The classic scheme of a manual pump. B – A variant of a homemade pump made of plastic pipes. Device diagram: 1 – inlet pipe; 2 – check valve; 3 – piston; 4 – check valve; 5 – stock; 6 – a stem, combined with a branch pipe; 7 – pump drain

For work we need:

1. Sewer pipe PVC 50 mm with bends, plugs and sealing collars – 1 m.
2. Check valve 1/2 “- 2 pcs..
3. Sewer pipe PPR O 24 mm.
4. Rubber, bolt / nut pairs with washers O 6-8 mm.
5. Clamps, sleeves, fitting clamps, other plumbing parts *.

* The design of the pump can be customized depending on the availability of spare parts.

Method 1. Draining through the handle

This model is the simplest of the domestic ones – water rises along the piston rod, which is made of PPR pipe and pours out from above.

Sleeve:

1. We cut off a pipe O 50 mm long 650 mm – this is the basis for the sleeve.
2. We make an end petal valve. To do this, drill 8–10 holes of 5–6 mm in diameter in the plug and cut out a round rubber flap (3–4 mm) for a diameter of 50 mm. We fix the flap in the center of the plug with a rivet or bolt (self-tapping screw does not fit!). Flap valve ready.
3. We install the plug into the pipe (sleeve) on the sealant through the seals and additionally fix it with self-tapping screws through the pipe wall.

Piston

1. We install a check valve in the PPR pipe (700-800 mm). This can be done in the “hot” way – to warm up the end of the pipe and insert a fitting with a valve into it, which should let water pass in the direction of the pipe (piston rod). Reinforce the connection with a worm clamp while warm (until it cools).
2. The piston head can be made from a waste tube of 330 ml sealant, or rather its nose. To do this, it must be preheated, placed in a sleeve – so the head will take on the ideally desired shape and size. Then it should be trimmed and installed on the non-return valve in series using a coupling with an external thread or a cap nut “American”.
3. We insert the piston into the sleeve and make the upper plug. It does not have to be sealed, just keep the stem straight.
4. Install a 90 ° squeegee on the free end of the stem (pipe). In the future, a hose is put on the squeeze.

Such a pump is very reliable, but not entirely convenient – the water outlet point is movable, moreover, it is located close to the operator. It can be slightly modified for convenience..

Method 2. Side drain

A 35 ° elbow tee should be included in the sleeve. The design is identical to the first option, but we make large holes in the piston rod pipe without violating the structural rigidity, or we use a rod rod. In this case, water will enter the sleeve and rise by the operator’s return force to the spout..

The main advantage of the described pumps is the low cost of the finished structure. Repair is carried out in a few minutes by replacing (or gluing) “cheap” parts.

Option No. 3. Spiral hydraulic piston

Behind this formidable name lies an ingenious device for supplying water from a river over a short distance. This device is based on a carousel with blades – similar to the wheel of a water mill. Carousel powered by river flow.

In this case, the pump is a spiral made of flexible pipe Ø 50–75 mm, secured with clamps to the wheel. In the intake part (closer to the outer contour), a bucket from a pipe of a larger diameter (150 mm) is attached to it.

The main unit is a pipe reducer through which water will enter the pipeline. It can be taken from factory equipment or a sewer pump. The gearbox is located along the axle of the wheel and is rigidly fixed to a fixed base.

The maximum water rise will be equal to the length of the pipe (from the intake), which is completely submerged in water during operation. That is, it is the distance in plan from the point of immersion to the point of exit that the water intake bucket passes. At the time of immersion, a closed system with air sections forms in the pipeline, and water flows through the pipe to the center of the spiral.

Of course, such a pump is not suitable for everyone – after all, the river is the activator. But for watering in the summer, this is a great option. The cost of such a device is difficult to predict – the availability of available material is of great importance.

Option number 4. Pump from the compressor (airlift – airlift)

If the farm already has a compressor, do not rush to purchase an additional pump. You can assemble a simple water lift from literally two pipes.

The first pipe serves to supply water. For household needs, O 30 mm will be enough. The second is needed to supply air from the compressor. Diameter 10–20 mm.

The efficiency of the airlift pump directly depends on the compressor power, immersion depth and delivery head. It cannot exceed 70% due to design features. The efficiency will be equal to the immersion depth divided by the sum of the immersion depth and the ascent height (total water path). In most cases, the optimal compressor power is set empirically..

Water supply has long been the number one task for the survival of entire cities. Today, saving energy and natural resources comes to the fore – they are becoming less and less expensive and they are becoming more and more expensive. Therefore, a partial return to the original technologies without electricity and gasoline is a natural phenomenon. Perhaps in the future, this will be the key to a healthy and harmonious life on our planet..
