aligned and, therefore, alignment must be established during installation. S.A.M. Engineering (Pty) Ltd
has determined that proper and correct alignment can only be made by accepted erection practices. Refer
to the following paragraphs on "Foundation", "Setting Base plate", "Grouting Procedure", "Alignment
Procedure" and "Doweling".
B. STORAGE:
1. Short term (less than 6 months): S.A.M. Engineering normal packaging procedure is designed to
protect the pump during the shipping. Upon receipt, store in a covered and dry location.
2. Long term (more than 6 months): Preservative treatment of bearings and machined surfaces will
be required. Rotate shaft several times every 3 months. Refer to driver, coupling and seal
manufacturers for their long term storage procedures. Store in a covered dry place.
C. LOCATION:
The pump should .be installed as near 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.
The pump must be primed before starting. Whenever possible, the pump should be located below the
fluid level to facilitate priming and assure a steady flow of liquid. This condition provides a positive
suction head on the pump. It is also possible to prime the pump by pressurizing the suction vessel.
When installing the pump, consider its location in relation to the system to assure that sufficient Net
Positive Suction Head (NPSH) at pump suction is provided. Available NPSH must always equal or
exceed the required NPSH of the pump.
The pump should be installed with sufficient accessibility for inspection and maintenance. A clear space
with ample head room should be allowed for the use of an overhead crane or hoist sufficiently strong to
lift the unit.
NOTE: Allow sufficient space to be able to dismantle pump without disturbing the pump inlet and
discharge piping.
Select a dry place above the floor level wherever possible. Take care to prevent pump from freezing
during cold weather when not in operation. Should the possibility of freezing exist during shutdown
period, the pump should be completely drained, and all passages and pockets where liquid might collect
should be blown out with compressed air.
Make sure there is a suitable power source available for the pump drive. If motor driven, electrical
characteristics should be identical to those shown on motor data plate.
D. FOUNDATION:
The foundation must be substantial enough to absorb vibration. (Hydraulic Institute Standards
recommend the foundation weight at least five (5) times the weight of the pump unit.) It must form a
permanent and rigid support for the base plate. This is important in maintaining the alignment of a
flexibly coupled unit.
Foundation bolts 6 mm smaller in diameter than the clearance holes in the base plate should be embedded
in the concrete to a depth of eight (8) times the diameter of the bolt and locked with either a hook around
a reinforcing bar or alternatively, a nut and washer at the bottom. The bolts should have a sleeve around
them at least six (6) times the bolt diameter long and at least two (2) bolt sizes larger in I.D. If a nut and
washer are used for locking, the washer should have an O.D. two (2) sizes larger than the sleeve.
The foundation should be poured within 20-40 mm of the finished height. (See Figure I) Freshly poured
