General Procedures
8.1 Record all data from the nameplates of the unit and motor on the appropriate locations of the Form FN 8.011.1 (Pump Test Report).
8.3 Test Data
8.2 Record all design values of the pump and motor data on the Form FN 8.011.1 (Pump Test Report).
8.3.1 Shut off the discharge valve(s) and energize the pump system.
8.3.2 Measure the discharge, and suction pressures of the pump using a differential pressure meter (water) at the test ports located at the inlet discharge of the pump, record readings.
8.3.3 Turn the pump off, open the discharge valve(s).
8.3.4 Turn the pump on and balance the pump system to the final design conditions, record readings.
8.3.5 Measure the discharge and suction pressure and head using a differential pressure meter (water), record readings.
8.4 Pump Data
8.4.1 Verify performance and impeller diameter by plotting the tested shut off head and actual operating head on manufacturer’s supply pump performance curve.
8.5 Motor Data
8.5.1 Measure the pump’s RPM using a tachometer.
8.5.2 Measure the voltage and amperes using a voltmeter and an ammeter.
8.5.3 Calculate the brake horsepower (BHP) of the motor using the following equation:
$$ { m BHP} = \frac{{NPHP \times MA \times MVolt}}{{NPA \times NPVolt}} $$
Where:
NPHP = Nameplate Horsepower
NPA = Nameplate Amperes
NPVolt = Nameplate Voltage
MA = Measured Amperes
MVolt = Measured Voltage
8.5.4 Record all data on the Form FN 8.011.1 (Pump Test Report).
9
Review and Approval
9.1 Return the Forms FN 8.011.1 (Pump Test Report) to the TAB Department for review.
