IMPORTANT TUBE INFORMATION
•
Always follow factory tube replacement and centering instructions.
•
Schedule a tube replacement at regular intervals according to the needs of the
specific application.
•
A used tube will have stretched approximately 3/4" and the new tube will appear
to be stiff and short. Allow the pump to run the roller assembly in its collapsed
position for approximately one minute to relax the tube as indicated in the tube
replacement instructions.
•
Replace ferrules with every tube change, ferrules are the seal between the tube fitting
and the connecting nut.
•
Only finger tighten the nut and ferrule. Over-tightening may result in a twisted
tube,damaged fittings, crushed ferrules and air pick-up.
NOTE: A twisted tube will not center and can decrease tube life.
•
For 26-100 psi applications, inspecting and replacing the duckbill at every tube
change is recommended.

pump tubes are not compatible with petroleum or oil-based products. Refer
to the Chemical Resistance Chart in the

for compatibility or call the factory.
•
DO NOT allow tube fittings to turn inside the pump housing when connecting suction and
discharge tubing. Tube will be forced off center towards cover and can wear a groove in
the tube, leading to leaks.
For maximum tube life, always identify the reasons for the failure and correct
the problem before a new tube is installed.
