Pump Warranty

Coolube® Lifetime Pump Warranty

In it for the long run!

At Unist, we’re committed to your long term success with MQL. We’re so confident in the quality of our Coolube® line of lubricants that we offer users the Coolube® Lifetime Pump Warranty.

The Coolube® Lifetime Pump Warranty means that Unist MQL system owners who use Coolube® exclusively in their systems enjoy a lifetime warranty on their system’s pumps. See details below.


When Unist MQL application systems are used exclusively with Unist Coolube® products, Unist warranties its positive displacement metering pumps for as long as the original purchaser owns the equipment (lifetime). Should a pump used solely with Coolube® fail, contact Unist to receive a pump rebuild kit free of charge.

The Coolube® Lifetime Pump Warranty only covers the life of the positive displacement pumps. Other parts are covered by Unist’s standard warranty terms. This warranty does not cover accidental damage due to operator error.

Unist is committed to customer satisfaction and we’re proud to offer this warranty. We know that quality fluids will improve any process and we stand behind our pumps and Coolube® products as a winning combination that is in it for the long run.
