Radial Piston Pump
Size 250 cm3
New version available for high
pressures up to 350 bar (5,000 psi)
hydraulic systems

A new version of the Moog Radial Piston pump is now available with variable
displacements up to 250 cm3 for applications requiring high system pressures up to
350 bar (5,000 psi) such as metal forming machinery and presses, heavy industry and
plastics machinery.
The new RKP 250 is the product of choice for highly dynamic control of hydraulic
flow and pressure. The pump is available in a high pressure version for continuous
pressures up to 350 bar (5,000 psi) and offers full drive-through capability. The pump
is designed to be used in open-circuit systems, has a large suction port and a flowoptimized suction path, ensuring robust suction behaviour, a high speed limit and
low noise. The 9-piston rotary group used in the RKP 250 has the typical minimized
piston clearance volumes leading to lowest pressure ripple and best noise emission
behaviour that is characteristic for this design.
Consistent with the design of the smaller RKP-sizes, the RKP 250 is also equipped
with the proven, robust control system with sliding stroke ring. The exclusive use of
ferrous metals with hardened, wear-resistant surfaces at the part contacts leads to
outstanding longevity of this product line in the field. This design also allows special
pump versions for use with HFC and HFD fluids.
Moog offers a modular design concept with a range of different compensator
options: Pressure compensator (F2), combined pressure and flow compensator (R1),
fixed displacement (B1), dual displacement (N1).
The RKP-D with a highly dynamic electro-hydraulic control (D1 to D8) can easily be
configured with the Moog Pump Configuration Software. Status information, set
values and actual values are displayed graphically for quick and easy performance
monitoring, trouble shooting and tuning.
