Pump monitor and dry run protector

The pump is the center of any circulating or fluid transfer system. The pump also has many moving parts during operation. Therefore, besides having a sound structural design, the pump must also be protected against abnormal operations and monitored for wear. We have two devices designed to protect the pump which is a dry run protector. The basic device (DRP-D) senses the current drawn by the motor to determine if motor loading is abnormal. Our advanced pump monitor (AVF-M) is designed to be inclusive of our canned motor pump series. Besides pump current monitoring, the pump protector monitor device also monitors other parameters to gauge pump health.

Overload and Dry-Run Protector

DRP-D

The pump protector system is a critical component within the pumping system. It is of utmost importance to ensure the pump runs smoothly. The DRP-D’s pump dry run protector main function is to protect the pump by monitoring the loading of the pump. The over-current setting protects the motor from overloading, while the under-current setting protects the pump during dry-run and decoupling to protect the pump from damage. By protecting the pump, we can prevent extended and costly production downtime.
