relay.
Name plate on typical pump motor.
d.
Locate the motor name plate on the pump motor housing. The full load
amp rating for the motor is listed on the name plate.
e.
Engage the electrical power supply and start the unit.
f.
The amp meter will display the motor amps. Compare the actual motor
amps as displayed on the amp meter to the full load amp rating as listed
on the motor name plate.
g.
If the amp draw is excessive (higher than the listed name plate amp
rating), a throttling valve must be installed in the “from process” water
line. The throttling valve can be a gate valve or a ball valve.
h.
With the throttling valve installed, fully close the valve and then engage
the pump motor. Slowly open the throttling valve and monitor the motor
amps as displayed on the amp meter until the actual motor amps
equal the listed full load amp rating of the motor. The process flow is
now correctly adjusted. The valve should remain in this position during
operation.
