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 FRBH 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.
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. Initial
levelling should be within 0.75 mm (.030 inches).
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.
With the aid of a machinist's level, adjust the wedges,
shims or jacking nuts to level the pump and driver
mounting pads in each direction. Check to ensure that
the suction and discharge flanges are plumb, level, and
at the correct elevation. It is normal practice to set the
mounting pads slightly low in order to permit lowering of
units which may be required to suit future piping or
minor changes. Place washers over the foundation
bolts and install nuts. Tighten finger tight only.
Check the impeller axial clearance and that the rotor
turns freely by hand.
Note: Grout is not poured until an initial alignment
of the pump and driver has been performed.
