High-Performance Rubber, Fabric-Reinforced & Thermoplastic (TPE) Pump Diaphragms - the Industry Standard

Wabtec pump diaphragms are produced from the highest quality materials and precision molds to ensure a long service life for this “heart valve” of the diaphragm pump. Our rubber/fabric-reinforced and thermoplastic (TPE) pump diaphragms offer a combination of performance and economic benefits.

  • Superb flex fatigue resistance, excellent abrasion resistance and good temperature resistance
  • Increased flex life results in less downtime, lower maintenance costs and lower replacement costs

In addition to our standard line of pump diaphragms, Wabtec Elastomers also offers custom molded pump & valve components.
