Introducing DiaFlex®
The worlds first single-layer injection molded PVDF diaphragm
Zero Breakdown • Zero Delamination
Innovative design for a longer-lasting diaphragm
Blue-White’s exclusive DiaFlex® High-Performance Diaphragm is constructed of PVDF for exceptional chemical compatibility and is manufactured 100% in-house.
DiaFlex® incorporates an innovative single-layer design, rather than the multiple layers of traditional diaphragms. Because there are no multiple layers, DiaFlex® diaphragms exhibit zero breakdown or delamination, virtually eliminating field maintenance and downtime.
Superior Chemical Resistance and Maximum Durability
DiaFlex has excellent chemical resistance to most chemicals especially tough acids like sulfuric acid and muriatic acid.
DiaFlex is designed to last the life of the pump minimizing maintenance costs and reducing exposure to chemicals during diaphragm replacement.
