Hydraulic Logsplitter Gear Pump, HI/LO, 3/4" pipe inlet, 1/2" NPT outlet, 13 gpm at 3600 RPM, Clockwise rotation.

Model GP-F2 is a HI/LO Hydraulic Gear Pump with a maximum pressure of 950 PSI for the low pressure pump and 3000 PSI for the high pressure pump.  The change from LO to HI pressure is automatic with the LO side pressure pre-set from 400 PSI to 900 PSI.  The HI/LO section of the pump is all aluminum and the endplates are cast steel.  The standard inlet is 1" pipe and the standard outlet is 1/2" NPT.

Applications for the HI/LO pump are log splitters, presses, etc., where rapid movement of the cylinder at low pressure is required prior to automatically switching to the high pressure mode to meet load requirements.
