PGP511 Parker Gear Pump 3349

PGP511 SERIES Gear Pump  Overview

The Parker PGP511 is a high-performance, fixed-displacement aluminum gear pump designed for demanding hydraulic systems that require high power density in a lightweight package. As a cornerstone of the PGP500 series, the PGP511 features a high-strength, three-piece aluminum construction that offers exceptional efficiency and reliability. It is the industry-standard choice for mobile and industrial applications where weight savings, heat dissipation, and continuous high-pressure performance are critical.

Features and Benefits

• High-Strength Three-Piece Aluminum Construction:
  The PGP511 is engineered with high-tensile, extruded aluminum bodies and die-cast aluminum covers, providing an excellent strength-to-weight ratio. This three-piece design enhances structural integrity and heat dissipation, allowing the pump to remain cool and efficient during prolonged operation in challenging environments.
• Advanced Pressure-Balanced Bearing Blocks:
  To ensure maximum productivity, the PGP511 utilizes sophisticated pressure-balanced bearing blocks. This technology automatically maintain optimal internal clearances, significantly reducing internal fluid bypass and friction. The result is consistently high volumetric and mechanical efficiency (often exceeding 95%) across a wide range of operating conditions.
• Precision-Engineered Low-Noise Gear Sets:
  Equipped with hardened steel gears featuring an optimized tooth profile, the PGP511 is designed to minimize pressure pulsations and operational vibration. This precision engineering leads to ultra-quiet operation, making it ideal for noise-sensitive applications and improving operator comfort in mobile machinery.
• Exceptional Durability and High-Pressure Capability:
  Despite its lightweight aluminum frame, the PGP511 is built for high-intensity duty cycles, capable of handling continuous operating pressures of up to  250 bar (3,625 psi). High-load capacity journal bushings and premium sealing systems ensure long-term durability and minimal wear under high-pressure service.
• Global Modular Versatility and Integration:
  The PGP511 series offers a comprehensive range of displacements (from  6.0 to 33.0 cc/rev) and supports a vast array of international mounting standards, including SAE, DIN, and ISO flanges. Its modular architecture allows for the easy configuration of multiple-stage (tandem or triple) pumps and the integration of specialized relief or priority valves.

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.
