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 always be located as near as
possible to the suction supply.
Install the unit close to the source of the liquid to
be pumped.
It is desired to simplify the suction and discharge
piping layout. When selecting the location, be sure
to allow adequate space for operation as well as
for maintenance operations involving dismantling
and inspections of parts.
Head room is an important consideration as an
overhead lift of some type is required.
There should be ample head room to allow the use
of an overhead crane or other lifting device with
sufficient capacity to handle the assembled pump
and the pump motor individually.
4.2 Foundation
The foundation may consist of any material that
will afford permanent, rigid support to the full area
of the pump supporting member and will absorb
expected stresses and shocks that may be
encountered in service. Concrete foundations
should be level and built on solid ground.
Foundation bolts of the specified size should be
located according to the pump template drawing.
When the pump unit is mounted directly on
structural steel framing, it should be located
directly over or as near as possible to the main
building members, beams, or walls. The soleplate
should be bolted to the steel supports to avoid
distortion, prevent vibration, and retain proper
alignment.
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.
The foundation should be sufficiently rigid and
substantial to prevent any pump vibration and to
permanently support the baseplate at all points.
The most satisfactory foundations are made of
reinforced concrete. These should be poured well
in advance of the installation to allow sufficient
time for drying and curing.
The General Arrangement Drawing (In Job’s User
Instruction) will furnish overall outline of pump
foundation plate, anchor bolt locations, size of
bolts, etc. in order to provide proper shape to the
primary concrete. Anchor bolts can be positioned
or by a special template (not supplied by
FLOWSERVE see figure 4.1 - 4.2) or by the
foundation itself if proper pockets have been
provided in primary concrete.
