Radial piston pumps
RKP / RKP-D
Variable-displacement RKP pumps serve open hydraulic circuits and pressure/flow control. RKP-D adds digital control, configuration and diagnostics, with analog command or industrial communication options.
01Mechanical, hydromechanical and electrohydraulic control options
02Multiple-pump combinations possible
03RKP-D: adjustment and diagnostics using MOOG software
04Versions for special fluids are selected separately
The model will be added to your request. The B.N. team will check its suitability for your operating conditions.

TECHNICAL DATA
Data with a source.
| Parameter | Value and reference conditions |
|---|---|
| Displacements on the product page | 19,32,45,63,80,140 cm³/rev; check the catalogue for additional sizes Source ↗ |
| Medium-pressure series | Up to 280bar continuous; depending on size and version Source ↗ |
| High-pressure series | Up to 350bar continuous for models 19,32,63,80,140 listed on the manufacturer page Source ↗ |
| Design | Open-circuit, variable-displacement pump Source ↗ |
| RKP-D | Displacement and pressure control with integrated digital electronics Source ↗ |
| RKP-D communication | Fieldbus or analog command; configuration software via CANopen or Local CAN according to the catalogue Source ↗ |
The page summarizes sizes verified on the product page; it is not a list of every RKP code. Do not apply 350bar to every displacement or fluid. Other sizes, tandem pumps and special fluids require verification against the catalogue and full code.
