RKP is the ideal solution for all types of industrial
applications. The RKP is already used in machines for
injection molding, die casting, forming equipment such
as presses and rolls, as well as in general hydraulic
applications. In the field of plastic and metal processing,
the RKP is used on equipment to produce plastic and
metal parts, for the packaging and automotive industries.
The RKP is also used in test equipment, construction,
rubber processing, and the mining industry.
The RKP is particularly well suited to applications where

power, low noise and robust design, in combination with
precision and speed are needed.

10. Dual Displacement, N1
To switch displacement volume from one defined stroke This control option is suitable for both variable speed
ring position to another, a switching valve is used. operation as well as displacement control with two
displacement stages and a constant speed.
The required minimum displacement volume (Vminimum) and
maximum displacement volume (Vmaximum) values can be When used as a variable speed pump, the displacement
mechanically set using an adjusting screw. volume can be adjusted to the respective point in the
cycle by switching between Vminimum and Vmaximum. As the
Factory setting: Vminimum = 0.5 x Vmaximum pump drive torque is reduced with Vminimum, both the
motor and frequency inverter may be smaller, depending
on the machine cycle.

Notes on Multiple Pump Circuits
In the case of multiple pumps, which deliver into one

circuit, the P-T control notch shall be activated only for
the compensator of the first pump by connecting the
T-connection to the tank. The T-connection of the
compensators of add-on pumps shall be sealed off.
Caution!
The tank line of the compensator should be open and

connected when operating as single pump.
