3. Connect the horizontal pipe or spool piece to the
elbow lower flange and tighten the flange bolts.
4. Check pump for level. Pump should be less than
1/2 degree (0.1”/ft) from horizontal so bearings are
not starved of oil (see Fig.15). Be sure thermal
expansion does not cause this angle to be
exceeded.
5. With the underslung arrangement install the motor
after the pump is connected to the piping. Be sure
motor shaft is parallel to the pump shaft in the
horizontal and vertical plane (see Fig.16).
6. If pump unit is direct drive utilizing a drive shaft,
refer to the drive shaft manufacturer’s installation
manual for mounting instructions.
NOTE: PIPE FLANGES MUST BE PARALLEL WITH
THE PUMP FLANGE BEFORE THE BOLTS ARE
TIGHTENED. If the flanges are not parallel, forcing
them parallel by tightening the bolts will cause
excessive strain on the pump.
CONNECTION OF PIPING
GENERAL
Never draw piping into place by
forcing at the flanged connections of
the pump. This may impose
dangerous strains on the unit and
cause misalignment between pump
and driver. Pipe strain will adversely
effect the operation of the pump
resulting in physical injury and
damage to the equipment.
Guidelines for piping are given in the “Hydraulic
Institutes Standards” available from: Hydraulic
Institute, 30200 Detroit Road, Cleveland OH 44145-
1967 and must be reviewed prior to pump installation.
WARNING
Never draw piping into place by forcing at the
flanged connections of the pump. This may
impose dangerous strains on the unit and cause
misalignment between the pump and driver. Pipe
strain will adversely affect the operation of the
pump resulting in physical injury and damage to
the equipment.
1. All piping must be supported independently of, and
line up with the pump flanges.
2. Piping runs should be as short as possible to
minimize friction losses.
3. DO NOT connect piping to the pump until the
pump and driver hold-down bolts have been
tightened.
4. It is suggested that expansion loops or joints be
properly installed in suction and /or discharge lines
when handling liquids at elevated temperatures,
so linear expansion of piping will not draw pump
out of alignment.
5. The piping should be arranged to allow pump
flushing prior to removal of the unit on services
handling corrosive liquids.
6. Carefully clean all pipe parts, valves and fittings,
and pump branches prior to assembly.
