Key Features
- Genuine OEM Construction — Manufactured to the original dimensional tolerances required for correct seating and retention force in diaphragm pump assemblies.
- Drop-In Internal Fit — Engineered to snap directly into the internal groove of the pump bore, requiring no special modification to the housing or adjacent components.
- Confirmed Fitment — Compatible with MQD2H, MQD3H, MQD2HA, and MQD3HA Multiquip diaphragm pumps.
- Maintains Pump Integrity — Keeps critical internal components properly positioned under operating pressure, preventing axial movement that can lead to accelerated wear or pump failure.
- Fast, Accurate Servicing — Using the correct OEM retaining ring ensures the pump is returned to service quickly without the risk of misfit or re-work during reassembly.
An internal retaining ring is a precision fastening component that snaps into a machined groove inside a bore or housing to hold shafts, bearings, or other internal parts securely in place. In a diaphragm pump, it prevents critical rotating or reciprocating components from shifting axially during operation, which is essential for maintaining pump output and sealing performance. When a retaining ring becomes worn, distorted, or fractured, the components it secures can migrate out of position, causing irregular pumping, increased wear on surrounding parts, or pump failure.
