Piston principle pump

Piston pump has been around for decades, its popularity depends on two main reasons:
1, they do not require external energy - the force of water to provide them with the required energy.
2, their equipment is extremely simple, with only two moving parts.
The basic principle is simple manual gas pump. Momentum This pump uses a relatively large movement of water to the relatively small volume of water pumped upward.
To use the plunger, there must be located above the water portable fuel transfer pump. For example, to have a pond on the hillside, so that you can install the water pump in the pond below. With a lead pipe water from the pond pump. Pumps have a valve that lets water flow through the pipes and acceleration.
