Moog Radial Piston Pump RKP
Outstanding Motion Control Solutions
For over 50 years, we have been a leader in motion
control technology, specialising in the manufacture and
application of high performance products. Today, we
incorporate the latest motion control technology into
our products and offer innovative ideas that can help our
customers achieve new levels of machine performance.
Proven Pump Technology
The Radial Piston Pump product line (also known as RKP),
is a range of high performance variable displacement
pumps intended for use in industrial applications. Based
on a proven concept, the RKP’s robust and contamination
resistant design results in long life and a high degree of
reliability.
Its rapid response time and high volumetric efficiency
have led to it being the first choice for many machines
with demanding flow and pressure control needs.
We produce a wide range of radial piston pumps of
different sizes, single and multiple arrangements, with
various forms of control (mechanical, hydro-mechanical,
electro-hydraulic, digital and analog) in order to provide
maximum flexibility to machine builders.
Applications
Thanks to the modular, high performance design, the
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.
Low-Noise and Rugged Design
With a number of innovative design features we have
been able to reduce both the primary and the secondary
noise level from the RKP. For sizes 63 and 80 cm
3
/rev,
the number of pistons have been increased from 7 to 9,
reducing the working piston diameter leading to lower
dynamic transverse forces acting on the housing.
As a result the flow and pressure pulsations on the high
pressure side have been reduced, enabling the RKP to
help machine manufacturers comply with EU directive
“2003/10/EC” on noise emissions.
The design minimizes wear on the internal pump
components, even under the most demanding operating
conditions, thereby extending the service life of the
machine.
Digital or Analog Control
The control technology of the RKP pump has been
significantly improved with a new integral closed-loop
proportional valve, with digital on-board electronics for
flow and pressure regulation, tuning, and diagnostics.
The RKP can be digitally controlled via a CANopen
or EtherCAT interface or controlled by analog
command signals.
Details of the significant benefits available from running
the RKP in either fieldbus or analog modes are outlined in
a separate catalog for the RKP-D pump.
GENERAL INFORMATION

Moog Radial Piston Pump RKP
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".
RKP stands for reliability, low noise, and durability and
this is underlined by its extended warranty. Under the
conditions described on page 5, warranty for mineral oil
is covered for 10,000 operating hours or 24 months.
Further Advantages of the Moog Radial Piston
Pump RKP are:
• Fast response
• Compact modular design enabling the pump selection
to match the application
• Good suction characteristics
• Low pressure ripple
The following RKP features are available:
• Medium pressure series (280 bar (4,000 psi)) and high
pressure series (350 bar (5,000 psi)) for mineral oil
• Large selection of compensators including mechanical,
hydraulic and electro-hydraulic (analog or digital with
CANopen or EtherCAT)
• Mechanical flow limitation
• Multiple pumps by tandem mounting
• Various drive flanges
• Suitable for most hydraulic oils such as mineral
oil,transmission oil, biodegradable oil and synthetic
esters (HFD)
• Suitable pump versions are also available for special
fluids such as oil in water emulsions, (HFA and HFB),
water-glycol (HFC), lubricating oils and cutting
emulsions. See the catalog Radial Piston Pump RKP for
Low-Flammability Fluids for details of these pumps.
Mode of Operation
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 balanced slipper pads (8). Piston
and slipper pads are joined by ball and socket joints which
is locked by a ring. The slipper pads are guided in the
stroke ring by two retaining rings (2) and, when running,
are held against the stroke ring by centrifugal force and
oil pressure. As the cylinder block rotates, the pistons
perform a reciprocating motion due to the eccentric
positioning of the stroke ring, the piston stroke being
twice the eccentricity. The eccentric position of the
stroke ring is controlled by two diametrically opposed
control pistons (6, 10) and the compensator (11). The
oil flow to and from the pump passes through the pump
ports and into and out of the pistons through the porting
in the control journal. The rolling bearing, supporting
the drive shaft, is only subjected to external forces.
The compensator setting limits the system pressure
and adjusts the pump flow between zero and full flow
to maintain the set pressure. At the RKP-D the position
of the stroke ring is detected by an LVDT (12) and high
dynamically controlled by a servo pilot valve (13).

280 bar (4,000 psi), 210 bar (3,000 psi),
150 bar (2,176 psi), 50 bar (725 psi),
the following considerations apply:
Design of 1st Through-Drive
The pressure and flow of the 1st pump stage are irrelevant
to the torque transferred by the through-drive. This
torque can be calculated using the above formula.

The value 318 Nm (2,814 lbf in) is below the threshold
value of 400 Nm (3,540 lbf in) specified in the above

Likewise, the value 96 Nm (850 lbf in) lies below the
relevant threshold value of 400 Nm (3,540 lbf in) for the
through-drive from RKP 63 to an RKP 32.
Design of 3rd Through-Drive Torque
Similarly, a value of 14 Nm (124 lbf in) is obtained for
the torque required to drive the add-on gear pump.
Thus, the through-drives for this pump combination are
permissible with the stated pressures.

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.

Moog Radial Piston Pump RKP
TECHNICAL DATA
!
Important
The pump shall be put into service by a trained hydraulic
systems engineer.
Installation
The radial piston pump can be mounted in any position.
The drive shaft shall not be subject to radial or axial loads
and should therefore to be driven through a flexible cou-
pling.
The pump shall be driven in the correct direction of
rotation. All plugs on the pump should only be removed
immediately before the pipes are connected and the
stan-
dard hydraulic cleanliness procedures have been done.
The use of cold
drawn seamless steel pipes in accordance
with DIN 2391 is recommended.
Suction Line (A)
It is recommended that final piping connections to the pump
are flexible hoses. The shortest possible suction line should
be used with a diameter large enough to give a fluid velocity
below 1.5 m/s (0.06 in/s). Sharp angles and screwed pipe
joints should be avoided due to the danger of air ingress and
excessive pressure drop therefore, pipe bends and/or hoses
should be used. The minimum permissible inlet pressure
shall be maintained. If a suction filter (minimum 0.15 mm
(0.01 in) mesh aperture) or an isolating valve is used, it shall
be installed below the fluid level.
Pressure Line (B)
Ensure the pressure pipework is securely clamped and
the screws are correctly torque tightened.
Drain Line (L)
The upper drain port shall be used for the drain line and the
pipework is to be routed to ensure the housing is always full
of fluid. The pipe should lead directly to the tank, separate
from other return lines. For RKP250 port L1 shall be used
for drain line connection. The bearing cover of the pump
shall be assembled with port L1 in upper position. For
descriction of port L2 see further information in chapter
“Flushing the housing”. It must terminate below the lowest
fluid level and should be as far away from the suction take
off as possible. Do not fit a filter, cooler or non-return valve
in the drain line. The maximum recommended length for
the drain line is 3 m (10 ft). The pressure at drain port is not
to exceed 1 bar gauge (14.5 psi) (2 bars absolute (29 psi)).
The recommended inside pipe diameters for drain lines
(lightweight version) are:
RKP 19: 11 mm (7/16")
RKP 32 and 45: 13 mm (1/2")
RKP 63, 80, 100 and 140: 17 mm (11/16")
RKP 250: 29 mm (1 1/8")
Flushing the Housing
For heat dissipation it is necessary to flush the pump
under the following conditions:
• Pump sizes 63 to 100 cm
3
/rev
If the pump is operated at low pressure without
flow for long periods (t > 15 min, p < 30 bar (435 psi),
Q = 0 l/min (0 gpm))
• Pump sizes 140 and 250 cm
3
/rev
Flushing of the housing is necessary in general at any time
The flushing line to the pump shall be connected to the
lower drain port. For RKP 250 the flushing line to the pump
shall be connected to port L2.

Noise Development
Radial piston pumps have a low primary noise level. However,
the overall noise level hydraulic of the unit depends on the
pump mounting and piping layout and the transmitted noise
can be prevented by:
• Connecting the pump to the bellhousing using an
anti-vibration flange.
• Use flexible hoses instead of solid pipes.
• Clamp the pipework with elastic insert clamps.
Connections
Suction line to port A and pressure line from port B.
Except for RKP 19 counterclockwise: Suction port B,
pressure port A.
Putting into Service
Do not start up the pump without hydraulic fluid.
Before switching on, the pump housing shall be filled
with hydraulic fluid using the higher drain port.
Jog start the electric motor to check the correct direction
of rotation. Run the pump at low pressure until the hydraulic
system has been fully de-aerated. When putting pumps
for HF fluids into operation, the system shall be run at low
pressure of between 30 to 50 bar (435 to 725 psi) for
approximately 1 hour.
Important
The fluid temperature in the tank shall not exceed the
temperature of the pump by more than +25 °C (+77 °F).
If this should occur, the pump shall be jog started for
intervals of approximately 1 to 2 seconds until pump casing
has heated up. When changing a pump, clean the suction
pipe, drain line and tank. Refill the tank with filtered fluid.

8. Constant Horsepower Control
General:
The constant horsepower control is designed in accordance
with the nominal power of the drive motor, which is not
exceeded at any operating point. Factory adjustment is
carried out at a constant nominal speed under measure-
ment of the drive torque.
Every pump is individually fine-tuned to ensure the
maxi
mum
possible hydraulic power output rate without
exceeding the available electric drive power. Deviations
with regard to the specified characteristic curves are there-
fore possible. The adjustment of the compensator is set via
the individual pressure range in each characteristic curve.
For single pumps, the following boundary conditions
apply:
∆p setting for S2 control option: 10+2 bar (145+29 psi)
∆p setting for S3 control option: 18+2 bar (261+29 psi)
For multiple pumps, the following boundary conditions apply:
Constant horsepower controls in multiple pump
arrangements are checked individually. The specified
power is related to the relevant pump stage.
∆p for constant horsepower controls with pressure and
flow control (compensator options S2 and S3) is set to
cascade in multiple pump arrangements.
∆p setting for S2 control option:
• Pump unit 1 = 11.5 bar (167 psi)
• Pump unit 2 = 10.5 bar (152 psi)
• Pump unit 3 = 10 bar (145 psi)
∆p setting for S3 control option:
• Pump unit 1 = 19.5 bar (283 psi)
• Pump unit 2 = 18.5 bar (268 psi)
• Pump unit 3 = 18 bar (261 psi)
In order to maintain stability of the system, this setting shall
be taken into account in case of repair or replacement.
Upon request, we can provide special settings optimized
for other speeds, powers or specific operating points.

Moog Radial Piston Pump RKP
TECHNICAL DATA
To switch displacement volume from one defined stroke
ring position to another, a switching valve is used.
The required minimum displacement volume (V
minimum
) and
maximum displacement volume (V
maximum
) values can be
mechanically set using an adjusting screw.
Factory setting: V
minimum
= 0.5 x V
maximum
APPENDIX A – COMPENSATOR OPTIONS
10. Dual Displacement, N1
This control option is suitable for both variable speed
operation as well as displacement control with two
displacement stages and a constant speed.
When used as a variable speed pump, the displacement
volume can be adjusted to the respective point in the
cycle by switching between V
minimum
and V
maximum
. As the
pump drive torque is reduced with V
minimum
, 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.
