Equipment that accurately tests all performance parameters of a pump with precision instruments is an all-in-one test bench. National standards for the B-level accuracy. The flow rate is measured with a precision worm gear flowmeter and the head is measured with a precision pressure gauge. Suction with a precision vacuum gauge measurement. Power measured with a precision shaft power machine. Speed ​​with tachometer. Efficiency according to the measured value: n = rQ102 calculation.
