3. SHAFT SEAL - (rotary seal). The shaft seal consists of two parts:
a. Rotating ceramic seal, press fitted into the impeller.
b. A stationary spring loaded seal, press fitted into the rear of the volute.
4. THE ELECTRIC MOTOR.
a. The electric motor should be protected from foreign matter, water splashing, hosing, and the
weather. Enclosures should be well ventilated to prevent overheating. If a motor becomes
wet, permit it to dry before running it. If a motor has been damaged by water or dirt, the
warranty is void.
b. The motors used on these pumps are 48 frame through bolt motors. The through bolts are
used to secure the volute to the motor. When replacing the motor, mark the end bells and the
motor shell to indicate alignment. Remove the four nuts from the through bolts at the shaft
end. Place the shaft through the back of the volute and locate the bolts in line with the brass
inserts located in the four legs at the rear of the volute. Be sure the end bell and the shell
marking line up. Securely fasten the motor to the volute.
c. Protect the motor from heat. Provide ample ventilation.
CAUTION
The highly polished and lapped faces of the seal are easily damaged. Handle with care.
This centrifugal pump requires little or no service, however the shaft seal will wear with normal use
over the years and will require periodic replacement.
ALWAYS MAINTAIN PROPER WATER LEVEL IN THE POOL. Water level must be half way up the skimmer
opening. A low water level can cause the pump motor to run dry which will damage the mechanical seal and
cause external leakage.
CAUTION
CAUTION
DO NOT RUN PUMP DRY. If the pump is run dry, the mechanical seal will be damaged and external
leakage will occur. When a seal is damaged, the seal must be replaced.
