Securing the EPX pump

Heavy objects can cause muscle strain or back injury. Use suitable lifting equipment to move the
pump. Refer to
For safety reasons you must make sure that any frame you mount the pump on is securely fixed to
the building structure or the assembly complies with clause 7.3 (stability) of EN61010-1. Secure
the EPX pump in its operating location. If you do not and the pump fails during operation,
movement of the pump may damage equipment and injure people.
In operation the surfaces on the top half of the pump can exceed 65°C; in certain fault conditions
these surfaces can exceed 105°C. If the pump is to be installed in a location where the surfaces
of the pump could be touched easily then the pump should be installed with adequate guarding.
1. Use suitable lifting equipment attached to the lifting bolts
required operating position. When installed, the EPX pump must be level: refer to
2. Fit a suitable M8 bolt, nut and washer through the exposed fixing hole in each of the vibration isolators (4 bolts
in total) (Figure 2, item 7), to secure the EPX pump to the floor, or to a frame; the floor or the frame must be
able to withstand a reaction torque of at least 1000 Nm (738 lbf ft), applied rotationally about the vertical axis
of the pump for at least 10 ms.
Note: The weight of the pump is evenly distributed across each of the vibration isolators. The position of the
centre of gravity is given in
3.4

Connect the inlet to your process system

Install the pump in the vacuum system before you connect the pump to the electrical supply. If
you do not, the pump may operate during installation and cause injury to people and damage to
the surrounding equipment.
Do not remove the Inlet screen from the pump. Do not operate the pump with the Inlet exposed.
You must be able to isolate the pump from the atmosphere and from your process system if you
have pumped or produced dangerous substances.
