Available from Custom Fluidpower , Parker Hannifin’s PGP020 gear pumps and motors are designed for the truck industry.

The ½" gears measure only 6" from mounting flange to the port end cover and weigh only 25lbs.

The bi-rotational motors and pumps can produce flows up to 29 gpm @ 2400 rpm up to 3000 psi, and output to 39 gpm @ 2400 rpm up to 2500 psi.

Parker Hannifin’s PGP020 gear pumps and motors are available in a range of drive shafts and mounting styles to meet specific requirements.

Key features of PGP020 gear pumps and motors:

  • Rigid one-piece drive shaft and gears
  • Pressure-balanced thrust plated design assures top efficiency
  • Rugged, high-strength cast iron body provides durability
  • Can be assembled in tandem to provide additional pump flow or more motor torque from the drive shaft
  • Each gear section is connected to the drive shaft by a connecting shaft
The strength of the drive shafts (PL factor) determines the maximum gear width the pump or motor can turn at a given pressure.

To determine the unit’s PL, the operating pressure (P) needs to be multiplied by the total gear width (L).

For instance, a PGP020 pump is operating at 3000 psi and has a 1.5" gear housing width. The unit’s PL factor will therefore be 4500 (1.5" gear width x 3000 psi operating pressure). This pump would need a drive shaft with a PL factor of 4500 or more to operate successfully.
