Polypropylene pumps are an economical alternative to stainless steel and can be a suitable substitute in a majority of applications. These pumps are usually combined with PTFE, Viton® or SantopremeTM diaphragms. When fitted with these elastomers a Polypropylene pump is ideal for pumping of fluids like benzyl, diacetone, phosphoric acid, ferric sulfate, isopropyl chloride, transformer oils and many other similar fluids.

PTFE Diaphragm

  • Excellent choice when pumping highly aggressive fluids such as aromatic or chlorinated hydrocarbons, acids, caustics, ketones and acetates.
  • Temperature range +40C to+1040C (+400F to +2200F)
