7 Installation
This section describes the installation of a complete
pump unit.
CAUTION
Installations should be performed by persons
qualified in the setting up of pumping
equipment.
WARNING
All electrical work should be carried out by
qualified personnel.
7.1 Location
WARNING
Engine-driven pump units:
The engine must be provided with adequate
ventilation to satisfy the requirements of the
combustion system, and allow adequate
dissipation of radiated heat and exhaust
emissions.
Install the pump in a well-ventilated, dry place above the floor
level wherever possible. Take care to prevent the pump from
freezing during cold weather when not in operation.
The pump should be installed with sufficient space around it
to facilitate ventilation and accessibility for inspection,
maintenance and service. A clear space with ample head
room should be allowed for the use of an overhead crane or
hoist to lift the unit.
Install the pump as near to the suction supply as possible,
with the shortest and most direct suction pipe practical. The
total dynamic suction lift (static lift plus friction losses in
suction line) should not exceed the limits for which the pump
was sold.
When installing the pump, consider its location in relation to
the system to assure that sufficient Net Positive Suction Head
[NPSH] is available at the pump inlet connection. Available
NPSH [NPSH
A
] must always equal or exceed the required
NPSH [NPSH
R
] of the pump.
The pump must be primed before starting. Whenever
possible, the pump should be located below the fluid level to
assure priming. This condition provides a positive suction
head on the pump. It is also possible to prime the pump by
pressurizing the suction vessel.
7.2 Foundation
We recommend that the pump unit should be installed on a
concrete foundation, sufficiently substantial to absorb
vibration and to form a permanent, rigid support for the
baseplate.
A base of concrete weighing 3 to 5 times the weight of the
pump unit is recommended.
The foundation should be 3 to 6 inches [75 to 150mm] longer
and wider than that of the baseplate that will be installed.
Foundation bolts must match those of the base plate. The
foundation should be poured without interruption to within 1/2
to 1-1/2 inches [12.7 to 38.1mm] of the finished height. The
top surface of the foundation should be well scored and
