4 inch Hydraulic Ram pump (DK-Z420T)
Features
Water hammer is a natural phenomenon. And the water pumps that created by water hammer have hundreds of years history. These pump devices can use the hydrodynamic force in low level to deliver high head water. As a tool of lifting with no consumption of electricity, oil and other traditional energy sources, it is very appropriate for the immigration and supply in mountain and semi-mountain areas with power shortage. And in areas with rich water resources, it can be used for power generation through water lift.
Derkor, with self-owned intellectual property right, is a new-type hydraulic ram pump invented by our company. Its lift efficiency is much higher and its property and status are more stable. Derkor can adjust hostile environment and bad conditions, and it can works without supervision and energy consumption for days and years. As a result, it is really environmental friendly and low carbon operation, leading to practical and profound significance of environment and energy.
Advantages
Use of a renewable energy source, does not consume traditional fuel(petrol diesel and electricity), no pollution.
High efficiency and high lift, long life (more than 30 years service life).
Automatic, continuous operation requires no supervision.
Simplicity and reliability give a low maintenance requirement.
Applications
The irrigation of Mountain, semi-mountain, hilly country.
The irrigation of near reservoir, river, stream area.
Drinking water for people and livestock at mountain area.
Supply water for landscape and fountain.
By use of the hydraulic ram pump to store energy for power generation.
The greening of barren hills.

Flow and Lift
Water lifting of the hydraulic ram pump depends on lots of factors, such as the water height, the working fall, the water of drive pipe needed, the angle between drive pipe and ground, and the lift etc. The working fall is bigger and the lift is smaller, the carry water will be more and more.
