PGP 500 pumps offer superior performance, high efficiency and low noise operation at high operating pressures. They are produced in four frame sizes (PGP 502, PGP 505,PGP 511, PGP 517) with displacements ranging from 0.8 to 70 cm³/rev. A wide variety of standard options is available to meet specific application requirements.
Characteristics
• Up to 280 bar continuous operation
High strength materials and large journal diameters provide low bearing loads for high pressure operation.
• Low noise
PGP 502 - 9 tooth gear profile, PGP 505 and 517 - 13 tooth gear profile, PGP 511 - 12 tooth
gear profile and optimized flow metering provide reduced pressure pulsation and exceptionally quiet operation.
• High efficiency
Pressure balanced bearing blocks assure maximum efficiency under all operating conditions.
• Application flexibility
International mounts and connections, integrated valve capabilities and common inlet multiple pump configurations provide unmatched design and application versatility.
• Large range of integrated valves
