Maintenance

General Maintenance

The M5 pump requires very little maintenance. However, the pump and all accessories should be checked weekly to ensure proper pump performance. This is especially important when pumping chemicals that may be extra corrosive. Inspect all components for signs of unusual wear, clogging, leaking, swelling, cracking, discoloration, or corrosion. Ensure rollers are moving freely and not straining or excessively wearing tubes. Replace worn or damaged components immediately. 

Replacing Tubes and Rollers  

The M5 pump is equipped with a Tube Failure Detection (TFD) that will sense a tube leak and stop the pump.  This feature will prevent the pump from running when there is a tube leak.   

When a tube leak occurs, or a tube needs to be replaced as part of periodic maintenance, the pump tube will need to be removed and a new tube will need to be installed. This process is quick and should not take more than a few minutes. Follow the steps below or watch the video at the bottom of this section.
