BACK PLATE 2" (50-055)
Part No: 50-055
Pack of 1
50-055: BACK PLATE 2" (50-055) – A 2-inch reinforced structural support disk installed directly behind the pumping diaphragm. It uniformly distributes mechanical push/pull forces from the central shaft and prevents structural bowing under pressure.

Key Features
- Oversized 2-inch structural backing plate built to rigidly reinforce high-capacity flexible diaphragms.
- Smoothly contoured outer radius margins eliminate sharp edge pinching to extend rubber lifespan hours.
- High tensile strength metal composition blocks flexible membranes from inversion during vacuum cycles.
- Precision counter-bored center template ensures concentric mechanical locking onto primary drive shafts.
- Dampens high-frequency operational stroke stresses to safeguard fluid cap hardware lines.
