REPLACEMENT
Check pump for shortage and damage immediately upon
arrival. Note damage or shortage on freight bill (bill of
lading); immediately file claim with carrier.
EXTERIOR
— Pay particular attention to conduit box,
external hardware and accessories. Touch up abrasions
or scratches with approved paint.
INTERNAL
— If extensive or serious external damage
is noted, if impeller is damaged (look in ports), or if shaft
binds or sticks, disassemble as required to permit
internal inspection.
Handle with care. Dropping or jarring can seriously
damage motor bearings or break pump parts. Lift with
device having capacity for pump weight, and use lifting
hooks or eye bolts (if provided) or rig double sling around
motor frame and pump casing. Do not use sling through
pump motor adapter.
Location
— Pump location should provide the
following:
1. Install as close to suction supply as possible.
2. Shortest and most direct suction pipe or hose
practical. Suction height will have a negative effect
on pump flow. The higher the lift, the more dramatic
the reduction will be. Maximum practical suction lift
is 25 feet vertically from the surface of the liquid.
3. Room for inspection and maintenance.
4. Correct power supply to motor; all wiring should
meet National Electrical and Local Codes and
Regulations.
5. If outdoors, protection from the elements, freezing
and water damage due to flooding.
Piping
— Suction and discharge gauges are useful to
check pump operation and are excellent trouble
indicators. Install gauges in the lines. Observe these
precautions when installing piping:
1. Support close to, but independently
of pump.
2. Use the next larger pump size for suction
and discharge.
3. Keep as straight as possible. Avoid bends
and fittings.
4. Remove burrs, sharp edges, ream pipe cuts and
make joints air-tight.
5. Don’t spring pipe to make connections.
Strain must not be transmitted to pump.
6. Allow for pipe expansion with hot fluids;
expansion joints are not recommended.
Suction
— Size and install suction piping to keep
pressure loss at minimum and to provide correct NPSH
by observing the following:
1. The suction pipe should be equal in size to the
suction connection of the pump. If pipe is larger
than the pump suction, an eccentric pipe reducer
should be used at the pump.
