Enhancing pump longevity

May 2014 Electrical Power & Protection

Motor failure in pumping applications can lead to unnecessary costs and loss of productivity. Therefore a good electronic motor protection relay is needed to protect against the pump running dry. When a pump operates outside its optimised load characteristics it will eventually fail. One aspect to monitor is load loss that can cause undesirable vibrations and subsequent rapid failure of the pump.

NewElec’s UCR 80 load loss protection relay is an ideal partner in a pump monitoring circuit because the user is able to monitor adverse load loss effects accurately. It is also possible to record impellor wear over time by periodic checks on the equipment. This allows the user to decide on the drop in efficiency level at which the impellor is to be replaced.

This relay provides dry run protection but can also be used to measure pump efficiency declines over time. It is equipped with an alarm and main trip output contact and is user-friendly. The UCR 80 provides blocked delivery or loss of prime in pumping applications and prevents conveyors running idle, as well as V-belt slippage.
