INSTALLATION
3.1
Location
3.1.1
It is desirable to locate the pump as close as possible to the supply source
(eg tank) in order to minimise suction losses.
3.1.2
The location should be dry and protected from rain and the possibility of
hosing down, with sufficient free space provided around the pump to
allow access for adjustment and maintenance.
3.1.3
The mounting surface should be even and level.
provided with two (2) holes for mounting bolts.

PIPING
4.1
General
4.1.1
The pump suction valve is located at the bottom of the pump head and
the discharge valve on top.
valves and for correct operation, valves must be vertical.
4.1.2
Discharge pressure should be more than 20 kPa greater than suction
pressure to prevent over feeding or syphoning and to maintain metering
accuracy.
NOTE
When the difference is less than 20 kPa, a back pressure valve and
pulsation dampener should be installed in the discharge line. The
pulsation dampener should be located between pump and valve,
as close to the pump as possible.
4.1.3
A characteristic of reciprocating pump performance is pulsating flow.
Piping should be sized for flow rates at least 3.5 times greater than
maximum capacity of pumps.
NOTE
Small diameter piping will produce unpredictable flow rates and
system pressures.
4.1.4
Piping should be as short and straight as possible and arranged to avoid
loops or pockets where gas may accumulate.
4.1.5
All piping should be separately supported close to the pump to avoid
imposing pipe loads on the pump.
temperature liquids, measures should be taken to prevent distortion of
piping imposing loads on the pump.
4.1.6
All pipe work should be flushed clean of any solids which may be present
in the pipe work (i.e. weldslag, dirt following construction or repair)
before final connection to the pump and start-up.
