Features & Benefits of Pure-Fuse Diaphragms

Wilden Pure-Fuse Diaphragms (IPD) feature a one-piece design that offers a safe, clean and reliable product transfer with no product entrapment areas to minimize product contamination and risk liabilities. These diaphragms have a smooth, contoured shape and no outer piston. IPDs have greater durability and flex life, and are compatible with existing shafts and supporting hardware. They also provide greater flow rates and faster installation, all without sacrificing performance.
