Description
All components are well proven and easy to service, and all hydraulic connections are located in the end plate.
The motor circuit on the DWP has a built in start/stop valve for remote start/stop, and has a flow regulator valve for speed control.
The pump circuit has a built in pressure relief valve.
The pump can be internally pressure compensated, remote pressure regulated or connected to a load sensing valve system.
