CONDITIONS THAT REDUCE TUBE LIFE
continued
CRACKED PUMP HEAD
The tube housing and latches can crack from wear, long term chemical exposure or due to
solution incompatibility with the housing material (refer to
Chemical Resistance Guide
).
SEIZED ROLLERS IN THE ROLLER ASSEMBLY
Corrosive chemicals that collect on the roller bushings, as a result of atmosphere or tube
failure, can result in seizing the rollers.
Corrective Action
1.
Confirm chemical compatibility with housing and pump tube material.
2.
Review factory recommended vertical pump installation.
3.
In the event of tube rupture, rinse the chemical residue from the housing and
roller assembly with factory recommended cleaners.
4.
If tube housing is cracked, replace.
Normal roller wear can cause a lack of output as a result of the rollers’
inability to fully squeeze the tube.
