Parker gear pump PGP505 series specifications

The following are the core specifications and technical characteristics of Parker PGP505 series gear pumps, comprehensive authoritative data collation:
Core performance
Working pressure: Continuous working pressure up to 275 bar (about 4000 psi), using high-strength materials and large shaft diameter design to reduce bearing load.
Displacement range: covering 0.8–52 ml/rev (or 0.8-52 cm3/rev), specific models are optional.
Speed range: standard speed 500-4000 rpm, suitable for a variety of working conditions.
Structure and design
Gear and noise reduction: 13-tooth gears are used to optimize the flow distribution structure, which significantly reduces pressure pulsation and operating noise; optional “secret trace” type for further noise reduction.
Material: Aluminum alloy shell combined with bronze balanced side panels to ensure structural strength and stability under high pressure.
Installation configuration:
It supports a combination of single pump, double pump or triple pump, and multiple pumps can be configured with a common inlet to save space.
Provide SAE flange, spline shaft, flat key shaft and other connection methods.
Function extension
Valve integration: pressure relief valve, load sensing valve, electromagnetic unloading valve, etc. can be built-in, suitable for power steering, braking system and other scenarios.
Shaft drive capability: support high-power through-shaft drive, expand multi-pump parallel applications.
Model example and selection
Typical model: PGP502A0036CP2D1NE2E2B1B1 (displacement 3.6 cm3/rev).
Naming rules:
Series number (PGP505) → displacement code (such as A0036=3.6cm3/rev) → shaft type/seal/pressure level and other configuration codes.

Application area
High-pressure hydraulic scenarios such as heavy-duty machinery, engineering equipment, metallurgy and material handling systems.
Note: The specific selection needs to be combined with the flow rate, pressure peak and environmental requirements (such as the low temperature sealing option H3 type). It is recommended to refer to Parker’s official technical manual.
