Selecting the right diaphragm for an air-operated double-diaphragm (AODD) pump is critical to the safety and efficiency of AODD pump operations. The right diaphragm will increase the reliability, performance and life of the pump, decreasing downtime and increasing profitability.
We offer diaphragms in multiple materials, including Neoprene, PTFE (Teflon), Nitrile (Buna-N), EPDM (ethylene propylene diene terpolymer) and Santoprene™. In addition to the multiple materials, Versamatic also provides different styles of diaphragms from domed and rugged to our groundbreaking FUSION™ with an integrated outer plate.
FUSION™
FUSION integrated-plate diaphragms go beyond bonding PTFE and rubber. They also meld the outer diaphragm plate into the design. This exclusive bonding process results in diaphragms that are stronger and longer-lasting than traditional designs.
Benefits of FUSION Technology
- Extended flex life
- Improved performance
- Greater displacement per cycle
- Eliminated leak paths
- Easy installation and maintenance
- Smooth, sanitary design
- Fewer parts, lower inventory costs
- Available for use in the majority of Versamatic pumps (½" to 3")
Domed
Versamatic’s domed diaphragms have a simple, smooth dome shape that delivers the flex across the entire face of the diaphragm, resulting in longer life. Because they’re so flexible, they can be installed and removed without the use of pry bars.
Benefits of Domed Technology
- Available in all rubber and thermoplastic materials
- Increased flex life over other diaphragm designs
- Eliminates complex angles that cause internal stress and limited flexibility
- Compatible with 1 ½", 2" and 3" pumps
Rugged
Eliminate your worries about diaphragm pump failure with Versamatic’s rugged diaphragms. Made of high-quality, fabric-reinforced rubber, these diaphragms outperform and outlive standard diaphragms.
Benefits of Rugged Technology
- Significantly reduces maintenance costs and downtime
- Standard diaphragm for most Versamatic pumps requiring rubber or thermoplastic diaphragms
- Available in Buna-N (Nitrile), Neoprene, EPDM (Nordel®), FKM (Viton®), Santoprene and Hytrel
Two-Piece PTFE
Since its introduction, this trusted diaphragm has a classic, reliable design providing chemical resistance and proven performance.
Benefits of Two-Piece Design
- Can be used universally in all non-abrasive applications
- Value option for chemical resistance and performance
- Available in ½", 1", 1 ½" and 3" diaphragms
2” (51MM) Aluminum Bolted
Offering a robust, leak-free bolted design, Versamatic’s 2” pump is engineered to seal even when pumping thin (low viscosity) liquids safely and with total confidence.
