PGP517 Parker Hannifin Gear Pump

PGP517 SERIES Gear Pump  Overview

The Parker PGP517 is a high-efficiency, fixed-displacement external gear pump from the PGP500 Series, engineered for compact, high-performance hydraulic systems in mobile and industrial equipment. Built with a lightweight yet robust three-piece aluminum construction, the PGP517 delivers a superior power-to-weight ratio, making it ideal for space-constrained applications requiring reliable, low-noise operation at continuous pressures up to 250 bar.

Features and Benefits

• Rugged Three-Piece Aluminum Construction

  The PGP517 features high-strength, lightweight aluminum bodies and covers, offering a compact footprint and low weight compared to cast iron alternatives. This three-piece design ensures precise manufacturing tolerances, minimizing internal deflection under high-pressure duty cycles and delivering consistent performance with extended service life in demanding mobile environments.

• Low-Noise 13-Tooth Gear Profile

  Featuring an optimized 13-tooth gear design, the PGP517 reduces pressure pulsation and vibration, resulting in exceptionally quiet operation. This low-noise profile is ideal for noise-sensitive applications such as electric/hybrid vehicles and indoor industrial machinery, while maintaining high volumetric efficiency across the operating range.

• Pressure-Balanced Thrust Blocks & Journal Bushings

  Equipped with pressure-balanced thrust blocks and large-diameter journal bushings, the PGP517 automatically optimizes internal clearances under varying loads. This advanced design minimizes fluid bypass and friction, ensuring high mechanical efficiency at all operating pressures while protecting the pump from premature wear, even with moderate fluid contamination and thermal shock.

• Superior High-Pressure Capability

  Engineered for heavy-duty use, the PGP517 delivers continuous operating pressures up to 250 bar (3,625 psi) with peak pressures up to 275 bar. High-strength alloy steel gears and precision-machined components allow it to power high-force actuators and complex hydraulic circuits with smooth, consistent flow, supporting speeds up to 3,400 rpm.

• Modular Versatility & Installation Flexibility

  The PGP517 series offers a wide range of displacements from 16 to 70 cc/rev, with support for standard SAE "A" and "B" mounting flanges, multiple shaft configurations (keyed, splined, tapered), and common inlet multiple pump designs. With integrated valve options and flexible porting layouts, it provides unmatched design versatility for crammed chassis environments and specialized mobile applications, including agricultural machinery, construction equipment, and material handling systems.

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
