5 PUMP PIPING - GENERAL
CAUTION: NEVER connect any pump to
piping, unless extra care is taken to measure
and align the piping flanges well. Always
start piping from pump. Use as few bends as
possible and preferably long radius elbows.
Do not use flexible connectors on the suction or dis-
charge of a vertical in-line pump, unless the pump is rig-
idly mounted to a foundation. Ensure piping exerts no
strain on pump as this could distort the casing causing
breakage or early failure due to pump misalignment. All
connecting pipe flanges must be square to the pipe work
and parallel to the pump flanges.
Suction and discharge pipes may be increased or
decreased at pump nozzle to suit pump capacity and par-
ticular conditions of installation. Use eccentric reducers
on suction connection with flat side uppermost.
Lay out the suction line with a continual rise towards the
pump without high points, thus eliminating possibility of
air pockets that may prevent the pump from operating
effectively.
6 APPLICATION
7 MECHANICAL INSTALLATION
7.1 Location
In open systems, locate the unit as close as practical to
the liquid supply source, with a short, direct suction pipe.
Ensure adequate space is left above and around the unit
for operation, maintenance, service and inspection of
parts.
In closed systems, where possible, the pumps should be
installed immediately downstream of the expansion tank/
make-up connection. This is the point of zero pressure
change and is necessary for effective pump operation.
Do not install more than one expansion tank connection
into any closed hydronic system.
Electric motor driven pumps should not be located in
damp or dusty location without special protection.
Airflow into the motor and/or motor fan should not be
obstructed.
7.2 VFD Mounting to Pump
For instructions on mounting the VFD directly to the
pump, see the diagrams and notes on the following page.
