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.
