How to make a manual water pump by yourself - manual and video

Probably, the question of making a hand pump by one's own hands is the most relevant for gardeners. In our time, manufacturers, and, in turn, the trading network, offer a wide range of different water pumps. They differ in power, and in type, and in value. But the vast majority of them are electrical.

However, many summer residents often face such a problem as the lack of electricity or the entire dacha massif or a separate block. Whatever it was, but to have a backup "installation" for pumping water is always necessary. Plants do not like to wait. They can not explain why the earth is cracking and who is to blame, that there is no water. Therefore, it is better to always have a manual water pump at hand, but that's the problem - it's almost impossible to find them on sale.

Principle and operation of the water pump

water-pump-1 In practice, hand-operated water pumps are manufactured in a piston type. To properly make such a pump, you need to clearly understand how it works. And it works very simply - in the cylinder moves the piston, which pushes the air out of it. A vacuum is created, and water comes( sucked in).The piston goes in the opposite direction, and after it a water column rises, which finds an outlet in the discharge pipe. Nothing complicated.




As a person works by hand, so does the water flow: either faster or slower. Of course, you do not pump a lot of water with such a pump( unless you have to take a break), but he always helps out. If the water lies at a depth of even more than 8 m, then such a pump will provide enough water. Only you need to know the differences between a conventional pump and a deep pump.

Pump for a depth of not more than 8 m

The housing of such a pump is a metal cylinder. Inside it, and moves the piston, which traction is connected with the handle "rolling".As such a cylinder( pump casing) it is possible to adapt a piece of pipe, a sleeve from a diesel engine, a body of a hydraulic cylinder. It's not difficult to pick up if you understand what's going to happen. The piston is made of a different material( metal, wood, plastic) - here everyone does, as it is more convenient. It must be sealed with a rubber ring. Everyone in his childhood at least once dismantled a hand pump for pumping a bicycle camera, so that the comparison is very close.

It should be understood that the pump's performance primarily depends on the valves - by-pass and reverse. Valves are holes in the lower cylinder cover and in the piston housing. When the piston moves to the lowest point, the water flows through the valve into the space above the piston. When the piston moves upward, it displaces this water into the discharge pipe. It should be either metal or reinforced. Do not use a clean rubber hose, since it will react to the pressure change inside the cylinder and constantly shrink.

Depth version of the pump

It is used if the water lies at a depth of more than 8-10 m. The pump is completely identical to its design described above, but there are some differences. The piston rod "walks" in the exhaust pipe itself, and it is not located on the side of the cylinder( in the upper part), but on its top cover. In view of the fact that the piston rod has an increased length, it is better to make it from a less heavy but reliable material. You can, for example, use duralumin pipes.

Valve for

pump Separate conversation about valves. As an option - to make membrane valves from a fairly strong( but not too thick) rubber. A piece of such rubber is attached to the valve opening. You can apply riveting, you can cogs - gadgets. The meaning of the valve is that when the rubber is pressurized with water, the rubber rises and lets in water. There is no pressure, and the hole is blocked - there is a mechanism such as a nipple. Although there are other models of valves.
