Parker Gear Oil Pump | PGP020

Parker PGP020 Series Fixed Displacement Gear Pumps

Strength & Reliability

Parker’s PGP020 Series fixed (positive) displacement gear oil pumps are engineered for high performance, long life, and resistance to oil contamination. Built with a cast iron housing and high-strength roller bearings, these pumps provide exceptional durability in demanding hydraulic applications where reliability and uptime are critical.

This pump is a part of Parker’s proven Commercial Intertech gear pump line, designed to handle high pressures and continuous-duty cycles. The heavy-duty cast iron construction resists wear from abrasive fluids and temperature fluctuations, while precision-machined components ensure tight clearances and smooth operation. Roller bearings on both ends of the gear shafts further enhance load-carrying capacity and service life, even under high side-load conditions.

Versatility

Available in both single and multi-section configurations, the PGP020 Series supports a wide range of flow and pressure requirements. Each unit is designed for compatibility with standard SAE mounting options and multiple shaft and port configurations, offering installation flexibility across mobile and industrial platforms.

Backed by Parker’s extensive testing and quality assurance standards, it maintains consistent performance, efficiency, and contamination resistance across its service life—making it a reliable choice for OEMs and fleet operators alike.
