PGP/PGM620 Series Gear Pump overview
The PGP/PGM620 Series Gear Pump from Parker is a fixed-displacement hydraulic gear pump designed for heavy-duty mobile and industrial applications. Its robust two-piece interlocking cast-iron construction delivers high volumetric efficiency, power density, and durability under high-pressure conditions. With displacements ranging roughly from 16 cm³/rev to 52 cm³/rev, continuous operating pressures up to 275 bar (4,000 psi), and speeds up to 3,500 rpm, the PGP620 series supports clockwise, counter-clockwise, and bi-rotational operation. Available in single, tandem, or multi-section configurations, it offers flexible mounting, shaft, and porting options, as well as a variety of integrated valve choices such as pressure relief and anti-cavitation features. This makes the PGP620 ideal for construction, material handling, agriculture, and other demanding hydraulic systems requiring reliable, high-performance gear pumps.
