© 2010 Moog GmbH User Manual RKP-II (CA53461-001; Version 2, January 2010) 7
2Safety
2.1 Intended Use
Intended UseThe Radial Piston Pump RKP-II is a work machine used to produce hydraulic
displacement. Certain versions of the radial piston pumps are fitted with an
additional safety function for locking (not a hermetic sealing function) the
hydraulic displacement.
Use Environment:
The radial piston pump is designed to control and regulate pressures and
displacements in commercial applications.
Obvious Misuse:
Operating the unit outside of the specifically defined application and
environmental conditions
in relationship to:
• Operating pressure
• Temperature
• Speed and rotational direction
• Operational environmental pressure
• Shock / vibration
• Electromagnetic interference resistance
• Operating fluids (viscosity, cleanliness class, chemical ingredients)
• Protection class
• Electrical and electromagnetic connections
• Operation in explosion hazardous areas if not permitted for such use
For incorporating into superordinate levels of machinery, the following
applies:
• The Radial Piston Pump is only to be operated as a component for a
complete superordinate system, e. g. in a machinery set up.
• The Radial Piston Pump is designed to be used with the specified
operating fluid. Use with any other operating fluid requires our express
approval.
• The efficient, reliable and safe operation of the Radial Piston Pump
requires quality project planning as well as professional execution,
transport, storage, mounting, demounting, electrical and hydraulic
connections, start-up, configuration, operation, cleaning and servicing.
The Radial Piston Pump may not be put into operation until the following
has been assured:
• The superordinate level machinery with all of its installed components
adheres to the relevant, nationally and internationally applicable
regulations, standards and directives (such as the EU Machine Directive
and the applicable regulations by the Employer's Liability Insurance
Association, TÜV or VDE) as amended.
• The Radial Piston Pump and all other installed components are in
technically sound and fail-safe condition.

skin contact.
• Wear suitable protective work equipment such as, e. g.,
work gloves.
CAUTION Noise Exposure!
When operating the machinery, the operator may be exposed
to loud noise, which can lead to hearing damage.
• The operator / manufacturer must take suitable measures
to protect against noise, such as, for example, instructing
the use of ear protection.
CAUTION Hazardous Operating Fluid!
When exposed to hazardous operating fluid, skin contact or
inhaling may lead to bodily injury.
• Wear suitable protective work equipment such as, e. g.,
work gloves.
