The Films Helping Pumps Deliver Optimal Performance

UHMW-PE Films for Pump Diaphragms

Industrial Applications

UHMW-PE or Ultra-High Molecular Weight Polyethylene polymers are widely used in various industrial applications due to their exceptional properties including high impact strength, low coefficient of friction, excellent chemical resistance, and abrasion resistance. 
These characteristics make UHMW-PE films suitable for various industrial applications, including those involving pump diaphragms.

How UHMW-PE Films Apply to Pump Diaphragms

Chemical Resistance

UHMW-PE is highly resistant to a wide range of chemicals, including corrosive and abrasive fluids. When used as a diaphragm material, UHMW-PE films can withstand exposure to aggressive chemicals without undergoing chemical breakdown or degradation.

Abrasion Resistance

Pump diaphragms can experience wear and abrasion due to the repetitive motion and contact with the fluid being pumped. UHMW-PE films have excellent abrasion resistance, helping to prolong the diaphragm's lifespan by reducing wear and tear.

UHMW-PE is compatible with a variety of fluids, making it suitable for use in diaphragms handling different types of liquids.


Proper engineering, material selection, and compatibility testing are crucial to ensure the optimal performance and longevity of pump diaphragms utilizing UHMW-PE films. But critically for bottom line, the material can extend the lifespan of pump diaphragms by resisting degradation caused by chemicals, abrasion, and other stressors.
