Asking “what is a hydraulic valve?” is like asking “how long is a piece of string?” The variations available to the hydraulic designer are absolutely astounding, not only because of the myriad types of valves on the market, but also because of the numerous manufacturers making them.
Driven by the motor, providing flow and pressure of the hydraulic actuator action desired. Thus, it can be said that the hydraulic pump is the “heart.” There are several types of hydraulic pumps: gear pumps, vane pumps, and piston pumps. Gear pumps. Compact hydraulic power units normally work with hydraulic gear pumps.
Hawe Hydraulics’ radial piston pump types R, RG and RZ have a closed pump housing. This means that the radial piston pump can be installed in the container of a hydraulic power pack as well as being used as a motor pump outside of an oil tank.
Screw pumps: std according to API 676, for mineral and lubricating oils also fluids with low lubricating properties (water+oil, HFC, LFO, HFO). Flows up to 5,000 litres per minute and pressure upto 130 bar (200 bar peak). Motor pump sets: close coupled, AC or DC electric motors. Pre-assembled systems: with bell-housing and coupling arrangements.
