Torque Optimization & Its Purpose in Pumps

Some of the challenges end users face with pumping systems are the natural frequency and vibration that occur during operation. Having a torque force that is consistent with the speed of the pump allows for smooth operation and effectively avoids the recurrence of troubleshooting. It is important operators are aware of the consequences of failing to optimize the torque in pumping units and the differences between speed and torquing.

Q: What Is Torque and Its Significance in Pumps?

A: Torque is often described as the measure of the force that is needed to cause an object to rotate about an axis. Simply put it is a turning force. A commonly used analogy is to think of the motion of a wrench against a bolt. In pump applications, such as hydraulic motor pumps or centrifugal pumps, it is described as a turning force that is calculated by horsepower, which is the combination of torque and speed, and can be referred to as revolutions per minute (RPM).
