What is Torsional Vibration?

Torsional vibration has been known to fail the gear rotor of oil pumps. Typically, the failure occurs during testing on an engine dynamometer at the OEM’s facility. A failure at this point is not only very expensive and time consuming, but it also doesn’t look good for the reputation of the oil pump supplier.
