Abstract
A reciprocating pump includes a chamber, a reciprocating member arranged to induct a fluid into the chamber and discharge the fluid from the chamber to a delivery side of the pump, and a piezoelectric element attached to the pump and arranged to detect pressure fluctuations on the delivery side of the pump so as to sense any abnormality in the inducting and discharging of fluid.
