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.
All equipment must be grounded.
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.
The pump should be located above the flood level.
The pipework should be such that there is an
adequate NPSH at the pump centreline. The
foundation should provide enough support so that the
pump is not supported by the pipework.
Refer to the general arrangement drawing for the
pump set.
4.2 Cleaning prior to installation
Remove glue and dirt from suction and discharge
flanges. Check motors to make sure no foreign
objects have entered through fan and cooling
openings. Remove any compounds on exposed
areas of pump shaft. Clean pump and motor
nameplate.
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 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.
4.3.1 General recommendations
Foundation bolts should be located or embedded in
the concrete by lay-out or template in relation to the
suction and discharge piping. Foundation bolts of the
specified size may be enclosed in a pipe sleeve two
or three diameters larger than the bolts to
compensate for minor variation in alignment.
Standard accessory steel baseplates furnished with
these pumps and motors 10 HP (7.5 kW) and under
may be bolted to machine or equipment structures,
either rigidly or, if flexible piping is used, with properly
designed vibration isolators.
A unit mounted on steel work or structural members
should be mounted over or adjacent to girders or
walls so that no misalignment will occur from yielding
or sagging of the structure.
Anchor bolts must be in accordance with the foot bolt
holes. Use anchor bolts of accepted standards and
sufficient to ensure seave fitting in the foundation.
Particularly, this applies to individual plates where the
anchor bolts have to withstand the driving torque.
Provide sufficient space in the foundation to
accommodate the anchor bolts. If necessary, provide
concrete risers.
4.3.2 Positioning on foundation
Pumps are generally shipped mounted, and it is
usually unnecessary with units of moderate size to
remove the pump or driver from its baseplate when
levelling.
Ensure the following are met:
a) Clean the foundation thoroughly.
b) The baseplate should be mounted onto a firm
foundation, either an appropriate thickness of
quality concrete or sturdy steel framework
capable of absorbing all normal vibrations. (It
should NOT be distorted or pulled down onto the
surface of the foundation, but should be
supported to maintain the original alignment).
c) Install the baseplate onto packing pieces evenly
spaced and adjacent to foundation bolts.
d) Level wi t h s hi ms , about 25 mm ( 1” ) , bet ween
baseplate and packing pieces.
e) Check the horizontal position by means of a
precision level placed upon an adequate
reference (discharge flange, machined surfaces
of casings etc...). Tolerances within 0.5 mm per
m (0.006 in per ft).
f) 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.
