The Multiquip 218100500 Oil Seal is a genuine OEM component designed for MQD2H and MQD3H diaphragm pumps. As an authentic Multiquip part, it is manufactured to the exact material and dimensional tolerances required for these machines, ensuring a proper seal under working conditions. If you are servicing either the MQD2H or MQD3H, the 218100500 is the correct OEM-specified seal for the application.
Key Features
- OEM-Grade Sealing Material — Manufactured to the precise compound and lip profile specified for diaphragm pump applications, maintaining integrity against fluid exposure and pressure.
- Drop-In Replacement — Dimensioned to seat correctly in the original bore without reworking the housing, making installation straightforward during routine service.
- Confirmed Fitment — Directly compatible with MQD2H and MQD3H Multiquip diaphragm pumps; part number 218100500 matches the OEM parts listing for both models.
- Leak Prevention — A correctly installed oil seal keeps lubricant contained within the pump assembly, protecting internal moving components from dry-running wear and contamination.
- Fluid Containment Compliance — Maintaining a functional oil seal prevents external leaks that can create slip hazards and environmental compliance issues on the jobsite.
An oil seal creates a dynamic barrier between a rotating or reciprocating shaft and the pump housing, keeping lubricating oil inside the assembly while preventing water, slurry, and debris from entering. In a diaphragm pump, a failed or worn oil seal allows oil to escape and contaminants to work their way into the drive mechanism, accelerating internal wear and leading to pump failure. Replacing a degraded seal promptly with the correct OEM part restores proper lubrication retention and extends the service life of the pump's internal components.
