Motor mounted pumps are built to operate without periodic
maintenance with the exception of lubrication of motor
bearings, if required. A systematic inspection made at regular
intervals, giving special attention to the following, will ensure
years of trouble-free operation.
Keep unit clean.
Provide the motor with correctly sized overload protection. Do
not oversize overload protection.
Keep moisture, refuse, dust or other loose particles away from
the pump and ventilating openings of the motor.
Avoid operating the unit in overheated surroundings (Above
100°f(40°c))

warning
Whenever any service work is to be performed on
pumping unit, disconnect power source to driver.
Any possibility of the unit starting while being
serviced, must be eliminated.
Series 4280 pumps, being motor mounted units, do not include
any pump bearings that require lubrication.
For the motor bearings: Follow the lubrication procedures
recommended by the motor manufacturer. Many small and
medium sized motors are permanently lubricated, particularly
at the pump end bearing.
Check the lubrication instructions supplied with the motor for
the particular frame size indicated on the motor nameplate.

Mechanical seal
Mechanical seals require no special attention. The mechanical
seal is installed behind the pump impeller, where it is cooled and
lubricated by the product being pumped.
Do not run the pump unless properly filled with water as the
mechanical seals need a film of liquid between the faces for
proper operation.
4 system cleanliness
Before starting the pump, the system must be thoroughly
cleaned, flushed and drained and replenished with clean liquid.
Welding slag and other foreign materials, stop leak and clean-
ing compounds and improper or excessive water treatment are
all detrimental to the pump internals and sealing arrangement.
Proper operation cannot be guaranteed if any of these condi-
tions are allowed to exist.
note: Particular care must be taken to check the following
before the pump is put into operation:
a Pump primed?
b Rotation ok?
c Lubrication ok?
d Pipe work properly supported?
e Voltage supply ok?
f Overload protection ok?
g Is the system clean?
h Is the area around the pump clean?
