Hy-Pro Drive PR+ RX/X PUMP WITH RELIEF VALVES
Item: PR+RX/X
MPN: PR+RX/X
The PR+ range of pumps is also available with relief valves which provide independent control of the maximum pressure available at each service port. Relief valves can be fitted to either 1 or both services. They are used in many applications worldwide including sports car suspension lifters, door and hatch openers and snow blowers.

Description
Utilising the standard PR+ pump and motor option, we have the addition of relief valve, to add to the versatility of the reversing pump range.
Complying with the small craft directives EMC and ignition requirements, this pump will have many onboard applications, that require load holding check valves.
In addition to Autopilot steering applications, the pump can be used in circuits requiring differing pressures for lifting and lowering. Hatch lifting, bathing platforms, gang planks etc
Application
This style of pump is suited to onboard applications requiring oil flows of 0.5 l/min to 2.5 l/min and pressures up to 55 bar. These will include auto pilot steering and hatch lifting.
It can also be used in automotive applications including suspension raising and hood lifting.
