2.2.3. Storage
If the pump is not to be installed and operated soon after arrival, store the pump in a clean, dry and frost-free place
with moderate changes in ambient temperature.
If the pump has regreaseable bearings, pump extra grease on bearings to prevent moisture from entering around
the shaft.
To prevent the pump from moisture, dust, dirt and foreign materials suitable steps should be taken.
The pump shaft should be revolved periodically (e.g. once a week) to prevent pitting of the bearing surfaces and the
pump from seizing up.
2.3. INSTALLATION ON SITE
Installation has to be carried out in accordance with EN 60204-1.
The pump should only be installed, levelled up and aligned by skilled personnel. Incorrect installation or defective
foundation could result in troubles. This would not be covered by the warranty.
2.3.1. Bare Shaft Pump
If the pump has been supplied with bare shaft end it is required to prepare a proper base plate on which to mount
the pump and motor assembly. The base plate must be properly designed and manufactured for enough rigidity to
prevent vibrations and distortions.
If the pump has been supplied without electric motor and coupling it is necessary to select a proper motor and
coupling before proceeding to the installation of the unit.
The following considerations must be taken into account for selection of motor:
Maximum power absorbed by the pump over the total operating range.
-
Pump operating speed.
-
Available power (frequency, voltage, etc.).
-
Motor type (TEFC, exproof, etc.).
