Description
"PR+RRV" reversing type gear pumps are driven by 12V/24V DC permanent magnet motors. Incorporated in the design are pilot operated check valves that prevent the pump being back driven by the manual steering system or rudder load.
The motors have an IP67 rating and can be removed from the pump without allowing air into the hydraulic system or fluid to escape. They can be used with both balanced and unbalanced cylinders. The pumps incorporate relief valves on each service port which allow the maximum pressure to be limited independently.
When used in conjunction with a cylinder of your choice, the PR+ RRV pump can be used for many onboard applications e.g. steering, hatch lifting, bathing platforms etc
