Brand C-Series Pump

Preliminary Test Run
Test the system using a preliminary run with the materials that will
be pumped. DO NOT run the pump to produce final product at
this time. See “Starting the Pump” on page 17.
Check for Possible Motor Overload Condition
Certain combinations will overload the motor when operated with
open unrestricted discharge, resulting in an unacceptably high
flow rate. Additional discharge restriction may be required to
lower the flow rate and lower the horsepower requirement. DO
NOT add any restriction to the supply line. If the pump was incor-
rectly selected, a smaller impeller or a higher motor horsepower
ma
y be required. If you are uncertain about pump selection and
application, temporarily install an ammeter in the electrical ser-
vice.
Ammeter Test
Operate the pump under process con
ditions and check the motor
amp draw versus the nameplate full load rating. If the amp draw
exceeds the motor rating, a system change or pump change is
required. If the process conditions and/or liquid changes (higher
viscosity, higher specific gravity), recheck the motor amp draw.
Contact your authorized SPX FLOW distributor for assistance.
The motor must be installed by qualified
personnel, e.g., a licensed electrician.
