Piping
•
Piping should be no smaller than the pump discharge.
Piping should be kept as short as possible, avoiding
unnecessary fittings to minimize friction losses.
•
All piping MUST be independently supported and
MUST NOT place any piping loads on the pump.
•
All joints MUST be airtight. Use 3 – 4 wraps of
Teflon™ tape to seal threaded connections.

Wiring and Grounding

pump.
Electrical supply MUST match pump's name plate
specifications. Incorrect voltage can cause fire and/or
damage to the motor and voids warranty.
Motors not protected MUST be provided with
contactors and thermal overloads on single phase
motors, or starters with heaters on three phase
motors. See motor nameplate.
•
Use only stranded copper wire to motor and ground.
The ground wire MUST be at least as large as the wire to
the motor. Wires should be color coded for ease of
maintenance.
•
Follow motor manufacturer's wiring diagram on the
motor nameplate or terminal cover carefully.

two power supply leads.
Installation
•
Minimum and maximum liquid levels must be
maintained for proper pump operation. See Figure 1.
