The Multiquip 213300000 Diaphragm Retainer Plate is a genuine OEM component designed for MQD2H and MQD3H diaphragm pumps. As a direct OEM replacement, it meets Multiquip's original design specifications, ensuring a correct fit within the pump assembly without guesswork or modification. This part is verified for compatibility with the MQD2H and MQD3H models, making it a straightforward service solution for contractors and pump operators keeping their equipment in peak working condition. Sourced directly through authorized Multiquip distribution, the 213300000 is the same retainer plate installed at the factory.
Key Features
- OEM-Matched Clamping Geometry — Manufactured to Multiquip's original retainer plate dimensions, ensuring correct diaphragm compression and sealing across the pump face.
- Direct Bolt-On Replacement — Mounts using the existing fastener pattern on MQD2H and MQD3H pump heads, with no drilling, re-tapping, or adapter hardware needed.
- Confirmed Fitment for MQD2H and MQD3H — Verified for Multiquip's MQD2H and MQD3H diaphragm pump models, so you can order with confidence.
- Protects Diaphragm Integrity — A properly seated retainer plate distributes clamping load evenly across the diaphragm, preventing premature tears, bypass leaks, and loss of prime.
- Genuine OEM Part — Sourced through authorized Multiquip channels; part number 213300000 matches the original component specification exactly.
The diaphragm retainer plate is the structural clamping component that secures the flexible diaphragm against the pump body, holding it in position so it can flex and displace fluid with each stroke cycle. Without a properly functioning retainer plate, the diaphragm can shift, buckle, or unseat, leading to fluid bypass, loss of suction, and eventual diaphragm failure. Replacing a worn, cracked, or warped retainer plate with the correct OEM component restores proper clamping load and extends the service life of the diaphragm itself.
