Coating gives major advantages to pump diaphragms

Tri-Ark has introduced a novel coating material for pump diaphragms which allows the flex life of neoprene to be combined with the chemical, temperature and abrasion resistance of Viton

Air Operated Double Diaphragm (AODD) pump specialist Tri-Ark has introduced a novel coating material for pump diaphragms which allows the flex life of neoprene to be combined with the chemical, temperature and abrasion resistance of Viton.

Tri-Ark can coat diaphragms from any AODD pump manufacturer with this new material, Tri-Fluor.

Tri-Fluor is based on Viton "B" material from Du Pont, with 50% added fluoropolymer (PTFE) to greatly enhance its performance.

Tri-Fluor coated neoprene offers a low cost alternative to diaphragms manufactured from Viton alone with a significantly improved flex life.

The coating exhibits very good physical properties and excellent adhesion.

Typical of all fluoro-elastomers, the cured coatings have very good temperature, chemical and abrasion resistance.

Tests have shown the fluoropolymer enhanced formulation to have increased (+20%) chemical, temperature and abrasion resistance.

Although neoprene diaphragms are known to have the highest flex life of all elastomers, the coating process is not restricted to this material.

Tri-Ark can coat diaphragms made from any elastomer with Tri-Fluor, should customers have a particular preference.
