The G4/5 DIAP-SANTO-FS diaphragm is made from an FDA-approved, food-safe Santoprene thermoplastic elastomer.
With normal use, this white diaphragm can be expected to last one or more maple seasons. It comes standard on the new QUAD pump and is also available as an option for GE single diaphragm and G2 double diaphragm Guzzler pumps.
Bosworth’s G4/5 style diaphragms fit all Bosworth 400 and 500 series pumps, regardless of diaphragm material.
