Waukesha Cherry-Burrell Installation

Preliminary Test Run Test the system using a preliminary run with the materials that will be
pumped. DO NOT run the pump at this time to produce final product.
See “Starting the Pump” on page 30.
Check For Possible Motor Overload Conditions
Certain combinations will overload the motor when operated with open
unrestricted discharge, resulting in an unacceptably high flow rate. Addi-
tional discharge restriction may be required to lower the flow rate and
lower the hor
sepower requirement. DO NOT add a restriction to the sup-
ply line. If the pump was incorrectly selected, a
smaller impeller or a
higher motor horsepower may be required.
If you are uncertain about pump selection and application, temporarily
install an ammeter in the e
lectrical service.
Ammeter Test
WARNING:
To avoid electrocution and equipment damage, only a
qualified electrician should install the ammeter.
Operate the pump under process conditions 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 chan
ges (higher viscosity, higher
specific gravity), recheck the motor amp draw.
