PL GEAR PUMPS

K1P Hydraulic Gear Pump
The pressure loaded (PL) hydraulic gear pump contains a pair of gears supported by two bearing blocks, housing and two covers. The axial clearance can be automatically compensated by the bearing blocks; the PL Pump features high mechanical and volumetric efficiencies, low noise level as well as low weight/power ratio.

HI/LOW GEAR PUMPS

K1P Hydraulic Gear Pump
The Hi/low 2-stage gear pump consists of a big displacement, low pressure pump and a small displacement, high pressure pump, a check valve as well as a unloading valve, while working at the pressure lower than the unloading pressure, both big and small pumps output flow. When working at a higher pressure, only small pump outputs flow, which reduces the power consumption.
MODEL SPECIFICATIONS

Rotation: CCW
Inlet Ports: 3/8 NPT Rear and 3/8 NPT Side
Sequence Setting: 200 to 800 psi; Preset at 600 psi
L: Distance from mounting face to rear cover
