  • This is a HI/LO hydraulic gear pump with 12 different displacement combinations with maximum pressures of 900 psi for the low pressure pump and 3000 psi for the high pressure. 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 end plates are cast steel. 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.
