3.4.3 Operating limits
Maximum pump speed: refer to the nameplate.
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
On baseplated pump sets the coupling elements
are supplied loose. It is the responsibility of the
installer to ensure that the pump set is finally lined
up as detailed in section 4.5.2, Alignment methods.
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, folded steel and cast iron
baseplates can be filled with grout. Polycrete
baseplates can not be grouted,see their User
Instructions 71569284 (E) for installation and use. 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 Initial alignment
4.5.1
Thermal expansion
The pump and motor will normally
have to be aligned at ambient temperature with an
allowance 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.
