Mounting, installation and connection
Overview
This section describes how to mount, install and connect the
pump. You get to know what to consider when you connect the
pump to the electric mains supply and how to improve the flow in
order to avoid dry running of the shaft seals.
4.1
Inspection before pump installation
4.1.1
How to check free running of the impeller
1. Remove motor shroud (if applicable).
2. Remove fan cover of motor.
3. Consider direction of rotation (arrow).
4. Rotate shaft slowly by hand via the fan.
The shaft must rotate easily. If the impeller rubs against the
pump housing, it has been damaged (for example during
transport).
If the impeller rubs against the housing, contact HILGE Ser-
vice.
If the impeller runs freely:
5. Re-fit fan cover of the motor.
6. Re-fit motor shroud (if applicable).

Pressure overload!
▲
Death, serious bodily injury, damage to prop-
erty.
►
The pump must be operated according to the
order data.
►
Never exceed the specified maximum operat-
ing pressures.
WARNING!
Misalignment of the pump due to improper foun-
dation!
▲
Death, serious bodily injury, damage to prop-
erty.
►
Ensure that the foundation on which the
pump is set up is clean and flat and has suffi-
cient load capacity.
►
The mounting points provided must be bolted
to the foundation according to the standard
rules of mechanical engineering to ensure
the satisfactory set-up of the pump.
