Proving Pump Efficiency by the Accurate Measurement of Shaft Power

Performing Pump Testing With A Highly Accurate Inline Torque Sensor

awak Aviation Technologies has developed a new line of “Jet Pump” (or JP) series helicopter refill system, allowing to draw water from practically any accessible water resource, decrease refilling cycle times without a need for landing and use the motor as the driver of an air conditioning system.

To perform accurate testing, they required a reliable product to measure shaft torque and speed on the motor and needed to make a choice between purchasing a commercial dynamometer or a highly accurate and reliable non-contact torque transducer. After making a comparison between products available on the market and consulting with the manufacturing partner, the Kawak team decided to use the Datum Electronics M425 Torque Transducer.

As a result of the accurate measurement of motor pump efficiency, the Kawak team was able to create new uses for the motor, namely as the driver of an air conditioning system where there is potential for much larger sales. Today, new JP series refill system a leap forward allowing Kawak to increase efficiency, sharpen reliability and improve performance of the refill pump.
