DIAPHRAGMS

Choosing the right diaphragm is essential for ensuring safe and efficient operation of air-operated double-diaphragm (AODD) pumps. A well-matched diaphragm enhances pump reliability, extends service life and optimizes performance, ultimately reducing downtime and improving overall profitability.

Versamatic offers a wide selection of diaphragm materials, including Neoprene, PTFE (Teflon), Nitrile (Buna-N), EPDM (ethylene propylene diene monomer) and Santoprene™. To meet diverse application needs, diaphragm styles range from standard domed designs to the innovative FUSION™ diaphragm, which features an integrated outer plate for added durability and performance.

FUSION™ Integrated-Plate Diaphragms

Versamatic’s FUSION™ diaphragms offer advanced technology that goes beyond simply bonding PTFE and rubber. These integrated-plate diaphragms incorporate the outer plate directly into the diaphragm structure, creating a stronger, more durable design that outperforms traditional diaphragms.

Key Benefits of FUSION™ Diaphragm Technology

  • Extended flex life

  • Enhanced performance and reliability

  • Greater fluid displacement per cycle

  • No external plate, eliminating leak paths

  • Quick and easy installation and maintenance

  • Smooth, hygienic surface ideal for sanitary applications

  • Fewer components, reducing inventory and maintenance costs

FUSION™ diaphragms are available for most Versamatic AODD pumps, from ½ inch to 3 inch sizes.

Rugged Diaphragms for High-Demand AODD Pump Applications

Versamatic’s rugged diaphragms are built with high-strength, fabric-reinforced rubber to deliver superior durability in demanding environments. These diaphragms are designed to outperform standard options, making them ideal for reducing maintenance costs and minimizing downtime.

Key Benefits of Rugged Diaphragm Design

  • Minimizes pump maintenance and reduces operational interruptions

  • Standard choice for most Versamatic pumps using rubber or thermoplastic diaphragms

  • Available in Buna-N (Nitrile), Neoprene, EPDM (Nordel), FKM (Viton), Santoprene and Hytrel materials

Domed Diaphragms for Versamatic AODD Pumps

Versamatic’s domed diaphragms are engineered with a smooth, rounded design that distributes flex evenly across the entire surface. This helps extend diaphragm life and enhances overall pump performance. Their flexible construction allows for easy installation and removal without special tools.

Key Benefits of Domed Diaphragm Design

  • Compatible with all rubber and thermoplastic diaphragm materials

  • Extended flex life compared to traditional designs

  • Eliminates sharp angles that create internal stress

  • Suitable for Versamatic 1½ inch, 2 inch and 3 inch AODD pumps

Two-Piece PTFE Diaphragms

Versamatic’s two-piece PTFE diaphragms feature a classic and proven design that offers excellent chemical resistance and reliable performance. This trusted diaphragm type has been widely used in various industries due to its durability and versatility.

Key Benefits of Two-Piece PTFE Diaphragms

  • Universally suitable for all non-abrasive fluid applications

  • Cost-effective option for chemical resistance and consistent performance

  • Available in ½ inch, 1 inch, 1 ½ inch and 3 inch sizes
