Gerotor Design: Gerotor pumps consist of an inner rotor with lobes or teeth that engage with the teeth of an outer gear. As the gears rotate, fluid is drawn into and pushed out of the pump's chambers.

Positive Displacement: Gerotor pumps are positive displacement pumps, delivering a consistent volume of fluid per revolution.

Compact Design: Gerotor pumps often have a compact design, making them suitable for installations with limited space.

Fixed Displacement: Gerotor pumps like the PGZ4 and PGZ5 series are typically fixed displacement pumps, meaning they provide a constant flow rate regardless of system pressure.

High Pressure Capability: Gerotor pumps are designed to handle various pressure levels, making them suitable for a range of applications.

Efficiency: Gerotor pumps are known for their efficiency and reliability in hydraulic systems.

Mounting Options: PGZ4 and PGZ5 gerotor pumps come in various mounting configurations to accommodate different installation requirements.

Applications: Gerotor pumps like the PGZ4 and PGZ5 series are commonly used in industrial and mobile hydraulic systems, including agriculture, construction, material handling, and more.

Bosch Rexroth PGZ pumps are low pressure, fixed displacement gerotor pumps. These pumps are suitable for applications such as cooling, filter or lubricant circuits with low pressures in industrial or mobile applications, e.g. plastics processing machines, machine tools, presses and wind turbines. Bosch PGZ pumps are available in two frame sizes: Frame size 4, PGZ4: 20 | 32 | 40 | 50 | 63 | 80 cc/rev. Frame size 5, PGZ5: 63 | 80 | 100 |140 cc/rev. Other features of Bosch Rexroth PGZ pumps include: Maximum operating pressure 15 bar; Very low operating noise; Suitable for broad viscosity and speed ranges; Very good suction behaviour; Application in cooling, filter or lubricant circuits with low pressures; Suitable for broad viscosity and speed ranges; Excellent suction characteristics; Can be combined with axial piston pumps, internal gear pumps and vane pumps.
