Excellent choice when pumping highly aggressive fluids such as aromatic or chlorinated hydrocarbons, acids, caustics, ketones and acetates. Exhibits good flex life compared to a standard diaphragm. Corrosive resistance centered on selection of materials. Safety is first and is evident in the rugged appearance of all Wilden pumps. Sturdy construction, specially designed clamp bands, and thick wall sections are testimony to the efforts of Wilden engineers.
Many factors can affect the chemical resistance of particular materials, especially plastics.
The fact that certain combinations of chemicals and mechanical load can induce stress cracking in many otherwise chemically resistant materials, both metallic and nonmetallic, is of particular significance.
