NEW Heavy Duty PTFE Diaphragms
Features
Overmolded design improves wear and double diaphragm life
No diaphragm plate is exposed on the fluid side
Longer double diaphragm life in more abrasive applications
New double diaphragms last longer and are considerably
stronger than other one-piece diaphragms, used with most
chemicals and ideal for a wide range of pumping tasks!!
