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.
Allow sufficient room to facilitate the back pull-out
feature on V-belt driven units.
Refer to the general arrangement drawing for the
pump set.
4.2 Part assemblies
Motors may be supplied loose on MARK 3 pumps,
typically on frame sizes 400 and above. It is the
responsibility of the installer to ensure that the motor
is assembled to the pump and lined up as detailed in
section 4.5.2.
4.3 Foundation
The foundation may consist of any
material that will afford permanent, rigid support to
the full area of the pump or driver supporting
member. It should be of sufficient size and mass to
absorb expected strains and shocks that may be
encountered in service. Concrete foundations built
on solid ground are desirable. Use a concrete grade
with a strength of approximately 20MPa (2900 PSI).
The purpose of foundation bolts is to anchor the
pump unit securely to the foundation such that the
foundation and pump assembly become a single
structural unit. High strength steel foundation bolts
(SAE Gr. 5 or equal) of the specified diameter should
be located according to the elevation drawing
provided. Each bolt should be surrounded by a pipe
sleeve which is two or three times the diameter of the
bolt. The sleeves should be securely anchored and
designed to allow the bolts to be moved to conform
with the holes in the baseplate. The bolts should be
sufficiently long to allow for wedges or shims or
levelling nuts under the baseplate, and a washer,
heavy hex nut and hex jam nut for retention. Since
baseplate levelling is performed after the foundation
has cured, it is best to use extra long bolts that can
be shortened after the installation is complete.
4.4 Baseplate installation
Position the baseplate and pump next to the
foundation and clean the foundation surface
thoroughly. Remove the rag packing from the pipe
sleeves and place wedges or ships as close to the
foundation bolts as possible. These may be omitted
if a jacking nut on the foundation anchor bolts is
preferred for levelling.
Remove the flange covers and check inside the
pump nozzles for cleanliness. Kerosene is
recommended as the best solvent for removing
factory applied rust preventative. Ensure that all
traces of rust preventative are removed from the
discharge and suction flange faces, the exposed
shafting and all coupling surfaces. Flush the pump
internals of any rust preventative applied for long-
term storage.
Lift the baseplate assembly, remove the shipping
skids and clean the underside of the baseplate.
Position the baseplate over the foundation and lower
the unit over the foundation bolts and onto the
wedges, shims or jacking nuts.
a) Level the pump baseplate assembly. If the
baseplate has machined coplanar mounting
surfaces, these machined surfaces are to be
referenced when leveling the baseplate. This
may require that the pump and motor be
removed from the baseplate in order to reference
the machined faces. If the baseplate is without
machined coplanar mounting surfaces, the pump
and motor are to be left on the baseplate. The
proper surfaces to reference when leveling the
pump baseplate assembly are the pump suction
and discharge flanges. DO NOT stress the
baseplate.
b) Do not bolt the suction or discharge flanges of
the pump to the piping until the baseplate
foundation is completely installed. If equipped,
use leveling jackscrews to level the baseplate. If
