Crane ChemPharma Flow Solutions, a manufacturer of fluid handling applications, has launched its new Depa Nopped S4 diaphragm for chemical processing applications.

The Depa Nopped S4 diaphragms are designed for applications in chemical industries, eg basic chemicals, paints, varnish, coatings, and heavy duty industries, for which they meet or exceed relevant industry standards.

A ‘nopped’ surface, has been designed to create flow conditions emulating the effect of golf all dimples. The use of Santoprene as its core material, a substance uniting elastomer (EPDM) and polypropylene (PP), in synergy with its chemical and mechanical properties offers flexibility and resistance against abrasion.

The DEPA Nopped S4 Diaphragms are interchangeable between various models of DEPA pumps.

The DEPA Nopped S4® Diaphragm is in compliance with Machinery Directive 2006/42/EC. It is available in 5 sizes from DL15-80 / ½” – 3”, it can operate within a temperature range of -20° C to +110° C (-4° F to 230° F), and a maximum 7 bar operating pressure.
