The Multiquip 213800090 Plunger Bearing is a genuine OEM component designed for MQD2H, MQD3H, MQD2HA, and MQD3HA diaphragm pumps. Sourced directly from Multiquip, this bearing meets the exact tolerancing and material specifications required for proper plunger operation in these pump models. Verified fitment across the MQD2H and MQD3H series means you can order with confidence and get your pump back in service without guesswork. DHS Equipment stocks genuine Multiquip parts to ensure you receive the correct replacement every time.
Key Features
- Genuine OEM Precision Tolerancing — Manufactured to Multiquip's exact dimensional specifications, ensuring the bearing seats and loads correctly within the plunger assembly.
- Direct Drop-In Replacement — Engineered to install in the same position and orientation as the original, with matching bore size and outer diameter for the plunger housing.
- Confirmed Fitment for MQD Series Diaphragm Pumps — Compatible with MQD2H, MQD3H, MQD2HA, and MQD3HA models; verify your model code before ordering.
- Sustained Plunger Stroke Accuracy — A properly functioning plunger bearing keeps lateral movement controlled, maintaining consistent stroke action and diaphragm actuation cycle after cycle.
- Wear-Resistant Construction — Built to handle the repetitive radial and axial loads generated by continuous pump cycling, resisting premature wear that can lead to plunger misalignment and diaphragm failure.
The plunger bearing supports and guides the reciprocating plunger shaft inside a diaphragm pump, keeping it aligned as it moves back and forth to flex the diaphragm and generate fluid displacement. Without a properly functioning bearing, the plunger can develop lateral play, causing uneven diaphragm wear, reduced flow output, and eventual seal or diaphragm failure. Replacing a worn plunger bearing promptly restores stroke consistency and protects the surrounding pump components from accelerated damage.
