The PH***S sealed hydraulic hand pumps are designed to pump hydraulic oil under pressure into 700bar(10,000psi) single acting hydraulic systems.
The Pumps are equipped with a single outlet port and a release valve. When the release valve is closed and the pump is cycled hydraulic oil is forced int to the hydraulic system under pressure – this may be a hydraulic lifting cylinder for example – further cycling of the pump will increase the pressure in the system until the maximum pressure is reached.
At maximum pressure an internal pressure relief valve will open, this prevents further cycling of the pump from increasing the system pressure.
The pressure will be held in the system untill the release valve is opened allowing the oil to return to the pump reservoir.
All RenQuip PH series hand pumps are two stage and fitted with a sealed reservoir. (please see description tab for the operational benefits)
It is important that the correct capacity of pump is selected for the system it is intended to operate.
- The PH300S has a reservoir capacity of 300cc
- The PH580S has a reservoir capacity of 5800cc
- The PH1100S has a reservoir capacity of 1100cc
The Pumps are supplied complete with hydraulic pressure gauges, gauge block and screw couplers.
