The equipment that can accurately test all the performance parameters of the pump is the full performance test bench. The national standard accuracy is Class B. The flow rate is measured with a precision gear flow meter, and the head is measured with a precision pressure gauge.
The suction range is measured with a precision vacuum gauge. The power is measured with a precision shaft power machine. The speed is measured with a tachometer. The efficiency is calculated according to the measured value: n=rQ102.
