Pumpar
Characteristics
Aluminium Body Gear Pumps
Series PGP500
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 (PGP511 also available as noise reduced “stealth“ version).
Technical data

Clockwise, counter-clockwise or double. Attention! Drive pump only in
indicated direction of rotation.
•Available in two or three section configuration.
•Max. shaft load must be conform to
the limitations shown in the shaft loading rating table in this catalogue.
•Max. load is determined by adding the torque values for each pumping section that will be simultaneously loaded.
Separate inlet configuration:
•Each gear housing has individual inlet
and outlet ports.
Common inlet configuration:
•Two gear sets share a common inlet.
