4 INSTALLATION
Equipment operated in hazardous locations
must comply with the relevant explosion protection
regulations. See section 1.6.4, Products used in
potentially explosive atmospheres.
4.1 Location
The pump should be located to allow room for access,
ventilation, maintenance and inspection with ample
headroom for lifting and should be as close as
practicable to the supply of liquid to be pumped. Refer
to the general arrangement drawing for the pump set.
4.2 Part assemblies
These pumps are not normally supplied in part
assemblies but special accessories such as loose
orifice plates are supplied loose. Ensure these are
incorporated in the final installation.
4.3 Foundation
There are many methods of installing
pump units to their foundations. The correct method
depends on the size of the pump unit, its location and
noise and vibration limitations. Non-compliance with
the provision of correct foundation and installation
may lead to failure of the pump and, as such, would
be outside the terms of the warranty.
Ensure the following are met:
a) The baseplate should be mounted onto a firm
foundation, either an appropriate thickness of
quality concrete or sturdy steel framework. (It
should NOT be distorted or pulled down onto the
surface of the foundation, but should be
supported to maintain the original alignment.)
b) Install the baseplate onto packing pieces evenly
spaced and adjacent to foundation bolts.
c) Level with shims between baseplate and packing
pieces.
d)
The pump and driver have been aligned before
dispatch however the alignment of pump and motor
half coupling must be checked. If this is incorrect, it
indicates that the baseplate has become twisted
and should be corrected by re-shimming
e)
If not supplied, guarding shall be fitted as necessary
to meet the requirements of ISO 12100 and EN953.
4.4 Grouting
Where applicable, grout in the foundation bolts.
After adding pipework connections and rechecking the
coupling alignment, the baseplate should then be
grouted in accordance with good engineering practice.
Fabricated steel, cast iron and epoxy baseplates can
be filled with grout. Folded steel baseplates should be
grouted to locate their packing pieces. If in any doubt,
please contact your nearest service centre for advice.
Grouting provides solid contact between the pump unit
and foundation, prevents lateral movement of vibrating
equipment and dampens resonant vibrations.
Foundation bolts should only be fully tightened when
the grout has cured.
4.5 Alignment of couplings
4.5.1 Thermal expansion
The pump and motor will normally have to be aligned at
ambient temperature and should be corrected to allow for
thermal expansion at operating temperature. In pump
installations involving high liquid temperatures, the unit
should be run at the actual operating temperature, shut
down and
the alignment checked immediately.
