A hydraulic piston or hydram is a cyclic water pump powered by hydroelectric power. It carries water to a "hydraulic head" (pressure) and flow, and emits water to a higher hydraulic head and lower flow. The device utilizes the water hammer effect to develop pressure which allows a portion of the intake water that feeds the pump to be lifted to a higher point than where the water originally started. The hydraulic piston is sometimes used in remote areas, where there is a low-power hydropower source and a need to pump water to a destination higher than the source. In this situation, the ram is often useful as it does not require any external source of energy other than the kinetic energy of the flowing water.
An alternative to the hydraulic piston is the water driven pump. It can be used if a high flow rate is required at high head ratio. A water driven pump unit is a hydraulic turbine coupled to a water pump. The driving power needed by the pump is generated by the hydraulic turbine from the available low head water power.

A hydraulic pump is a water pump powered by water with a height difference. In areas where there are natural flows with a difference in water height at a small distance, hydraulic plunger pumps can be used to transport water to higher ground without using electricity or fuel. The hydraulic piston uses the water hammer effect to develop pressure that allows a portion of the incoming water that feeds the pump to rise to a higher point than where the water originally began. Apart from the kinetic energy of water, no other source of energy is needed.
The hydraulic piston pump was invented in 1772 and widely used in the 19th century, but was side-tracked by the advent of the coal-fired steam engine and later by the diesel pumps. In recent years the hydraulic pump has seen renewed interest as it is driven by sustainable energy, and can be produced locally.
