Key Features
- Rigid structural backing washer designed to distribute longitudinal stroke forces across the diaphragm.
- Contoured smooth radius edges eliminate sharp pinch points to maximize elastomer flex life.
- Heavy-duty construction keeps the flexible membrane from turning inside out during suction cycles.
- Provides a solid mechanical anchor point for high-torque fastening onto the central piston rod.
- Resists high dynamic shear stresses to protect wetted pump parts from fatigue fractures.
