The Multiquip 336009200 is a genuine OEM Diaphragm Retainer Plate designed for MQD2H and MQD3H diaphragm pumps. As a factory-sourced component, it meets the exact material and dimensional specifications of the original part, ensuring a correct installation with no guesswork. This plate is a critical internal component that secures the diaphragm in position during pump operation, making accurate replacement essential to restoring full pump function. Confirm your model number against MQD2H or MQD3H before ordering to ensure compatibility.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and thickness specifications, ensuring the retainer plate holds the diaphragm under correct compression without distortion or misalignment.
- Direct-Fit Replacement — Engineered to seat exactly as the original, aligning with existing fastener patterns on MQD2H and MQD3H pump assemblies for a straightforward swap during service.
- Verified Fitment — Compatible with Multiquip MQD2H and MQD3H diaphragm pump models; verify your model code before purchasing.
- Restores Pump Integrity — A worn or cracked retainer plate allows the diaphragm to shift or flex unevenly, disrupting flow and pressure. Replacing it with 336009200 restores consistent pumping action.
- Fluid System Safety — Proper diaphragm retention prevents bypass or uncontrolled fluid discharge during operation, keeping the pump running within its designed pressure range.
The Diaphragm Retainer Plate is the structural component that clamps and secures the flexible diaphragm inside the pump head. It distributes clamping force evenly across the diaphragm's perimeter, allowing it to flex correctly with each pump stroke while preventing it from shifting out of position. When this plate is damaged, warped, or missing, the diaphragm cannot seat properly, resulting in loss of prime, reduced output pressure, or fluid leaking past the pump head.
