SAFETY WARNINGS
BEFORE OPERATING OR
INSTALLING THIS PUMP, READ
THIS MANUAL AND FOLLOW
ALL SAFETY RULES AND
OPERATING INSTRUCTIONS.
SAFETY
CAUTION
• Review instructions before operating.
WARNING - ELECTRICAL PRECAUTIONS
All wiring, electrical connections, and system grounding must
comply with the National Electrical Code (NEC) and with any local
codes and ordinances. Employ a licensed electrician.
CAREFULLY READ THESE SAFETY
MESSAGES IN THIS MANUAL AND ON PUMP.
WARNING - RISK OF ELECTRICAL SHOCK
• Have an electrician provide electrical power to the motor.
• Motor must be grounded and terminal cover in place to reduce
electrical shock hazard.
• Keep motor operating area as dry as possible.
• A ground fault interrupter (GFI) protected circuit is recommended for use with any electrical device operating near water.
• Always disconnect power before servicing.
• Not investigated for use in swimming pool areas.
APPLICATION
This pump is suitable for installations where the vertical distance
from the pump to the water level does not exceed 25 ft. In all

INSTALLATION
PUMP LOCATION: The pump should be installed in a clean, dry
and ventilated location which provides adequate drainage and
room for servicing and protection from freezing temperatures. It
should be bolted down evenly on a good foundation, preferably
concrete, to prevent the development of unnecessary stress.
Locating the pump as close as possible to the source of water
supply reduces the friction losses in the suction pipe and provides
for maximum capacities.
SUCTION PIPE: It is recommended that only new clean pipe or
installations, friction losses in the suction pipe must be taken into
consideration.
hose be used and the size be the same as that of the pump
suction tapping. If the pump is installed any appreciable distance
away from the source of water supply, the suction pipe should be
increased by one size. The suction pipe must always slope
upwards from the water source to the pump to avoid air pockets
in the line. In cases where the pump has to be reprimed often and
it is not necessary that a lot of water be delivered, it is advisable
to use a 90° or 45° elbow on the suction line. This enables the
pump to prime sooner and also prevents kinking of the hose. In
cases where a maximum volume of water is required over a pro-
236222 0403
longed period of time, the suction line should be led almost horizontally to the pump. Non-toxic thread compound should be used on all
pipe joints and connections should be thoroughly tightened. A
strainer should be connected to the bottom end of the suction pipe
and it should be well submerged at all times.
WARNING - RISK OF ELECTRICAL SHOCK
• WIRING: Make sure the voltage and frequency of the power
supply agrees with that stamped on the motor nameplate. If
in doubt, check with the power company.
WARNING - ELECTRICAL PRECAUTIONS
All wiring, electrical connections, and system grounding must
comply with the National Electrical Code (NEC) and with any local
codes and ordinances. Employ a licensed electrician.
SINGLE PHASE: Determine incoming voltage to motor. Where
possible, use 230V. Connect wiring to terminal board located inside
motor end cover. Be sure voltage connections agree with wiring
diagram on motor nameplate.
THREE PHASE: Three Phase motors require magnetic starters,
and can run in either direction, depending on how they are connected to the power supply.
OPERATION - PRIMING THE PUMP
To Check for Proper Rotation: Remove the motor end cover.
This exposes the motor shaft. If hookup is correct, the shaft will
rotate clockwise. If rotation is not clockwise, reverse any two leads
to the starter. The rotation will now be correct.
WARNING - RISK OF ELECTRICAL SHOCK
GROUNDING THE MOTOR: WIRING TO THIS PUMP MUST
BE INSTALLED AND MAINTAINED IN ACCORDANCE WITH
THE NATIONAL ELECTRICAL CODE OR YOUR LOCAL
ELECTRIC CODE. IF MORE INFORMATION IS NEEDED,
CALL YOUR LOCAL LICENSED ELECTRICIAN OR YOUR
POWER COMPANY.
It is recommended that a permanent ground connection be made to
the unit using a conductor of appropriate size from a metal underground water pipe or a grounded lead in the service panel. Do not
ground to a gas supply line. Do not connect to electric power supply
until unit is permanently grounded. Connect the ground wire to the
approved ground and then connect to the terminal provided.
WARNING:
PRIMING THE PUMP: A priming plug is provided in the top of the
casing to fill the pump with water. Once filled and the priming plug
replaced, the pump will prime. The priming time depends upon the
vertical and horizontal distance between the pump and the water
level. The pump should prime itself time after time as long as the
built-in check valve functions.
CAUTION:
PRIMING UNDER PRESSURE: (Refer to Figure 1) Should it be
necessary to prime under pressure, place a check valve on the
discharge line of the pump and a pet cock or a ball type air bleeder
in place of the priming plug, or an air bleed line with a gate valve
connected to the discharge line. It will then be possible for the liquid
to remain in the discharge pipe and allow the pump to bleed off the
remaining air, thereby facilitating priming.
IMPELLER ROTATION: The impeller must rotate in a counterclockwise direction as seen facing the pump from the front of the
casing. In the event of wrong rotation for electric motor models,
refer to the instructions furnished with the motor. The rotation of
three phase motors can be changed by interchanging any two lead
wires.
STARTING THE PUMP: Never operate the pump dry as this may
damage the seal. If an exceptionally long suction line is used, the
water in the pump casing may become overheated or vapour
locked. Should this occur, replace the water in the casing with cold
water and continue priming.
DRAINING: Should the pump be subject to freezing temperatures,
it will be necessary to drain the pump completely. To drain, remove
the drain plug located at the bottom of the front face of the pump
casing and the priming plug and make sure that the drain
DO NOT RUN THE PUMP BEFORE PRIMING IT, SINCE THE SEAL AND IMPELLER COULD BE PERMANENTLY
DAMAGED.
DO NOT run the pump before filling the pump
case with liquid, as it may damage the seal.
hole is not restricted. After all the water has been drained,
operating the pump for a few seconds will ensure that the impeller
is devoid of water (make sure that the suction line is also devoid
of water).
STORAGE OF PUMP: Drain liquid from pump to prevent freezing. It is recommended that a good rust inhibitor be put in the
liquid end to prevent excessive corrosion. Be sure motor is kept
dry and covered. When restoring the use of the pump, replace all
plugs and make sure all connections are tightly sealed. After a
complete check is made, make the initial prime according to
directions under the section, Priming the Pump.

LUBRICATION:
a) The pump requires no lubrication.
b) For electric motor models, refer to instructions provided
by the motor manufacturer.
REPLACING MECHANICAL SEAL:
(Refer to Figure 2)
TO DISASSEMBLE:
TO REASSEMBLE:
a) Clean all parts thoroughly.
b) Wet the rubber part of the seal seat with soap solution
and press it into its housing in the seal plate or adapter,
smooth ceramic surface facing outwards.
c) Assemble the seal plate or adapter to the motor.
d) Oil the seal and slip it into the motor shaft. Make sure
the sealing face is towards the ceramic seat.
e) Replace the impeller.
f) Reassemble to the casing and diffuser ring. It is
recommended to use a new gasket (3).
g) Reconnect the suction and discharge piping and re-
connect the electrical wiring.
PRECAUTIONS
a) Whenever pump is dismantled and then reassembled,
always check to see that the impeller rotates freely within
the casing.
b) The SPM models have a flinger (10) on the shaft. This
flinger must not be removed.
a) Remove the bolts (1) and remove the casing (2).
b) Remove the impeller (unscrew impeller or remove retain-
ing bolt depending upon the model).
c) Slip the seal off the shaft.
d) Remove the four bolts and lift the adapter (7) off the motor.
Take care not to damage the seal seat.
e) If the seat (9) needs to be replaced, push it out of the
adapter from the motor side.
