RADIAL PISTON PUMP - 4

Moog Radial Piston Pump RKP product description Quiet and Robust Design The RKP pumps benefit from low noise levels Sizes 32 to 250 are fitted with a sliding stroke ring. The big suction port supports the use of wide suction lines. The control port of the compensators is build in G 1/4". The shaft (5) transfers the drive torque to the star-shaped cylinder block (3), free of any transverse forces via a crossdisc coupling (4). The cylinder block is supported on the control journal (1). The radial pistons (9) in the cylinder block run against the stroke ring (7) through hydrostatically...

Technical Data Moog Radial Piston Pump RKP MULTIPLE ARRANGEMENTS Additional pumps can be tandem mounted on the radial piston pump, so that all pump stages can be driven by the same shaft. Radial piston pumps (the same size or smaller than the first pump stage) can be mounted directly. Other pumps may be added on using adapter flanges for SAE-A, SAE-B or SAE-C respectively. For the maximum permitted through-drive torque for driving add-on pumps, please refer to the table below. Adding on RKP, SAE-A, SAE-B or SAE-C Adapters Permissible Through-Drive Torques Pump stage 1 Pump stage 2 RKP...
