The introduction of the H800 expands Wilden’s application range to include head pressures up to 250 psig. Wilden’s patent pending high pressure technology yields a 250 psig discharge pressure designed for solid laden slurries. Capable of generating 250psig with only 85 psig air supply. Standard material compose of stainless steel casing with PTFE backed diaphragm. Suitable for boosting air line pressure over long distances.
