1. INTRODUCTION
1.1 Application
Betex® EP13, EP18 and EP211 series electric hydraulic pumps are for driving hydraulic systems. The pumps
are equipped with an on/off switch, emergency stop and remote control. The pumps are supplied without oil in
the reservoir.
1.2 Application areas
Betex® EP13, EP18 and EP211 series electric hydraulic pumps are suitable for use in an industrial
environment. The pumps are not suitable for explosive, highly flammable or corrosive environments. Using the
pumps in a medical or humid (>90%) environment is not permitted.
1.3 Principles of operation
Betex® EP13, EP18 and EP211 series electric hydraulic pumps work with a displacement pump which brings
the hydraulic oil to a maximum pressure of 700 Bar (10,000 PSI). This displacement pump is powered by an
electrical motor. The electrical energy is converted into hydraulic energy by the electric hydraulic pump. A pre-
mounted valve allows one to connect the electric hydraulic pump to fittings which convert the hydraulic energy
into, for example, mechanical energy, depending on the application.
2. SAFETY
2.1 Warnings
 Do not use the electric hydraulic pump in an explosive or highly flammable environment.
 Connecting fittings that are unable to cope with the maximum pressure (700 Bar/10,000 PSI) is not
permitted.
 Check whether the pump is safely connected to all the fittings used and whether the installation can be
operated safely before operating the electric hydraulic pump.
The electric hydraulic pump may not be used outdoors.

2.2 Safety risks
 Pressurized fluid: risk of oil injection in case of a leak.
 Noise level 81dBA
 Electrocution by incorrect earthing of the electric hydraulic pump.
2.3 Safety provisions
 Emergency stop
 On/off switch
 Overpressure valve set to 700 Bar (10,000 PSI)
2.4 Inadvisable use
Do not use the electric hydraulic pump at pressures higher than 700 Bar (10,000 PSI).

 Do not use the electric hydraulic pump in places where the pump can come into contact with liquids.
2.4 Safety measures (to be applied by the user)
 When the electric hydraulic pump is used in an installation where something moves in a vertical plane,
hose rupture protection must be fitted directly to the lifting cylinder.
 The electric hydraulic pump must always be properly connected to an earthing conductor. The electric
hydraulic pump may not be turned on when this is not present.
Electric hydraulic pumps with single-function valves (pumps without a 'D' or 'DS' suffix) may not be

connected to a double-function cylinder, unless measures are taken to prevent overpressure in the cylinder.
 The complete installation must be checked to see whether it satisfies the minimum safety requirements of
the most recent version of the Machinery Directive. Then a presumption of conformity must be drafted,
before the installation is operated, according to appendix 2A of the Machinery Directive.
