Hi Lo Pumps

• Filtration: 25 micron or better

• Oil Viscosity: 6 to 200 cSt

• Inlet Pressure: 12 to 32 psi absolute

• Displacement: (LO) 0.464 in3/rev

Hydraulic Gear Pump AP-HL

AP-HL is a HI/LO cast iron Hydraulic Gear Pump with a max pressure of 900 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 and the end plates are cast iron. 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.
