The best way to select a tube is to decide which
materials are chemically suitable, and choose the
one which best meets the physical demands of
your application. The longest tube life material
will usually be Marprene
®
.
Given proper chemical
compatibility, Marprene
®
will deliver thousands of
hours of service at a fraction of the price of
diaphragms, rotors, stators and other traditional
pump replacement parts.
•
For maximum tube life use a large bore tube
at low speed.
Choosing the right tubing: where to start
•
For maximum flow rate use the largest
tube at maximum speed.
•
For maximum accuracy use a small
bore tube at high speed.
Suction lift depends on the tube restituting
fully before the advance of the next roller. If
it does not, the flow rate will be reduced.
For maximum suction lift use the smallest
practical bore size of tubing and run the
pump at the slowest speed.
LoadSure

elements have rugged industrial
connections in PVDF that offer exceptional
resistance to chemicals attack. There are no
metallic components in the product zone.
