Maintenance

General Maintenance                                              

The M1 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 M1 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.  

1. Disconnect the system plumbing from the pump tube adapters. 
2. Press the Start/Stop key to stop the pump. 
3. Remove the three black thumb screws from the front of the pump head cover by unscrewing them counterclockwise. 
4. Remove the pump head cover by pulling straight out. 
5. Press the Start/Stop key to stop the pump. 
6. Set the motor speed to 10%. Press the Start/Stop key to start the pump. 
7. With the pump running, pull the inlet (suction) fitting out of the pump head. Guide the tube counterclockwise away from the rollers. Pull the outlet (discharge)fitting out of the pump head. 
8. Press the Start/Stop key to stop the pump. 
9. Thoroughly clean the pump head and rotor. The rotor can be removed by pulling it straight out. After cleaning, push the rotor back on the shaft. 
10. Set the motor speed to 10%. Press the Start/Stop key to start the pump. 
11. Insert the inlet (suction) side of the pump tube fitting into the lower retaining slot of the pump head. Carefully guide the pump tube into the pump head. 
12. Stretch the tube slightly and insert the outlet (discharge) fitting into the upper retaining slot of the pump head. 
13. Pull the outlet fitting out of the pump head. 
14. Place the clear cover onto the pump head. Secure the cover with the provided three thumb screws. The pump is now ready for operation.
