Blue-White Industries has introduced the Single Layer Injection Molded PVDF Diaphragm for the Chem-Pro® Series C2 and C3 Metering Pumps. Manufactured 100 percent in-house, this single piece, longer lasting diaphragm design does not consist of multiple layers like traditional diaphragms, is available in three various sizes and retro-fits onto current ProSeries® Chem-Pro® pumps. The pump head consists of only one material, PVDF, reducing chemical compatibility issues of the wetted parts.
