PGP511 Parker High Pressure Gear Pump Aluminum

Product Overview

The PGP511A0270AL6H2NE6E5B1B1 (and PGP511B0160, PGP500, PGP505, PGP517 series) is a high-pressure aluminum external gear pump from the Parker PGP500 series. Featuring a high-strength aluminum housing and precision gear design, it delivers high power density, high efficiency and low noise. With a wide displacement range (approx. 4–33 cm³/rev) and continuous pressure up to 250 bar, the pump offers direct bolt-on interchangeability with OEM units and undergoes 100% simulated duty testing for reliable performance in material handling, agriculture, turf and industrial hydraulic systems.

Application Areas

• Material handling equipment
• Agricultural and turf machinery
• Industrial hydraulic systems
• Mobile equipment auxiliary circuits
• Applications requiring compact high-pressure aluminum gear pumps

Expert Maintenance Tips

• Confirm rotation direction and flange/shaft compatibility before installation; use recommended hydraulic oil and maintain proper cleanliness.
• Start at low speed unloaded; check for leaks and noise. Avoid simultaneous maximum pressure and maximum speed.
• Regularly inspect seals and bearings; ensure unrestricted suction lines to prevent cavitation.
• Keep oil temperature and viscosity within recommended ranges; avoid over-pressure operation.
• For special codes, verify the complete order code and consult technical support.
