The Multiquip 214800000 is a genuine OEM Oil Seal 1-1/4" x 1-3/4" x 1/4" designed for MQD2H, MQD3H, MQD2HA, and MQD3HA diaphragm pumps. Sourced directly from Multiquip, this seal matches the exact dimensional and material specifications of the original component, ensuring a proper fit within the pump housing without any rework or modification. Verified fitment covers the MQD2H, MQD3H, MQD2HA, and MQD3HA series, making it a straightforward like-for-like replacement when servicing these units. Keep a spare on hand to avoid extended pump downtime during high-demand operations.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Multiquip's original compression and material specifications for this exact seal dimension, maintaining a leak-free barrier in the pump assembly.
- Exact Dimensional Match — The 1-1/4" inner diameter, 1-3/4" outer diameter, and 1/4" width are identical to the original, allowing the seal to seat correctly in the bore without shimming or adjustment.
- Confirmed Fitment for MQD Series Diaphragm Pumps — Fits MQD2H, MQD3H, MQD2HA, and MQD3HA diaphragm pump models.
- Pump Shaft Protection — A properly functioning oil seal prevents lubricant loss around the rotating shaft, protecting internal pump components from accelerated wear caused by oil starvation or contamination ingress.
- Fluid Containment Compliance — In pump applications, a compromised shaft seal can allow oil to migrate into pumped media or cause external leakage; using the correct OEM seal ensures the pump meets expected operational standards.
An oil seal — sometimes called a shaft seal or lip seal — serves as a barrier between rotating and stationary pump components, preventing lubricating oil from escaping the housing while blocking external contaminants such as water, dirt, and debris from entering. In a diaphragm pump, maintaining a sound oil seal is essential to keeping the drive mechanism properly lubricated and the pumped fluid free from contamination. When this seal wears or hardens with age, oil leakage and increased shaft wear follow quickly, making timely replacement critical to sustained pump performance.
