Pillarhouse use a highly accurate pump motor system that maintains a constant RPM.

However, a secondary system is now being offered to monitor the rotation speed of the pump spindle.

A high temperature gear tooth sensor senses the rotation of the pump impellor pulley, and will give alarm conditions if the pump speed deviates from the programmed speed.

This option guarantees that in the absence of any alarm, the pump impellor is rotating at the correct pre-programmed speed and so eliminates any operator uncertainty.
