01

Pump Performance Test

The pump performance test checks whether the pump delivers the specified flow rate, head, and efficiency. During the procedure, the pump is connected to a test rig with calibrated instruments, and the flow rate is changed using a throttle valve. The flow rate, discharge pressure, suction pressure, power consumption, and efficiency are measured. The measured results are then compared with the manufacturer’s performance curves to see if the pumps are working satisfactorily or underperforming.

02

NPSHr test

The main purpose of this test is find the NPSHr to prevent cavitation at the pumps inlet section. The Net Positive Suction Head available or NPSHA is given to the manufacturer for designing, if the measured NPSHR (actual measured value) is less than NPSHA, provided by the customer; then the NPSH test is considered satisfactory.

03

Mechanical run test

After completing the pump performance test and net positive suction head test, The mechanical integrity of the pumps is checked via mechanical run test. The operating parameters such as bearing temperature, lube oil temperature and pressure, shaft speed and vibration, mechanical seal leak rate, power consumption etc are checked and recorded.
