In the private sector, it is not always possible to connect to a centralized water supply, so each owner tries to equip a well near the house. At the same time, it is not necessary to carry water in buckets. A piston pump can supply it directly to your home.
The principle of operation of the device is quite simple. With some effort, the piston in the cylinder moves up and down. The rod is then passed through a flange with a rubber seal, which is located on the top cover. A pipe joins the bottom of the device, it has a piston. When it drops, water passes upward through this hole, while the valve at the bottom of the device is closed by water pressure. If the piston begins to rise, then the water that is above it begins to pour out through the outlet pipe. At the same time, the bottom valve opens, and the liquid again accumulates inside the device.
The piston pump now does everything automatically. It is enough to install it correctly and connect it to the power supply. Moreover, all components of the device must be strong and reliable, especially the inlet pipe through which water is supplied into the pump. Otherwise, the draft can provoke adhesion of its walls.
Also, the piston pump must be equipped with robust check valves so that they do not allow water to return back to the inlet hose. They can be membrane or ball. If a round valve is used, it is desirable that it be made of glass, hard rubber or heavy plastic.
However, the fact that the devices are not designed for a depth of more than 8 meters should also be taken into account. If the distance from the surface to the groundwater bed is large enough, in this case you will have to install a submersible pump. The fact is that atmospheric pressure can interfere with the normal operation of the device.
It should be noted that not always a device that is powered by an electrical network can perform its function without failures. The fact is that from time to time in the network there may be failures. In this case, a manual piston pump can be extremely useful. Although today such devices have not been used for a long time and it is quite difficult to buy them. It will be useful in the event that you do not plan to spend all the time on the site, are not going to use water every day.
You can build a piston pump yourself, especially since you can find a lot of design schemes for the device. However, it is better to buy the device from an agile manufacturer.
Both at home and on an industrial scale, axial piston pumps are used. They have less weight, small dimensions, can work at high speeds, and they are also easy to mount and maintain. The device is unpretentious in use, it can be easily repaired in case of breakage. The only drawback may be its cost, which is often quite high. It can also be used in the hydraulic drive of aircraft, machine tools, bulldozers and other large machines.
