The Multiquip 214900000 is a genuine OEM Internal Spur Gear designed for MQD2H, MQD3H, MQD2HA, and MQD3HA diaphragm pumps. Sourced directly from Multiquip, this part meets the exact specifications required to keep your pump's drive mechanism operating as intended. It is a direct-fit replacement for the original gear, requiring no modification to install. Whether you are completing a scheduled service or addressing unexpected gear wear, the 214900000 is the correct OEM component to restore full pump function.
Key Features
- Genuine OEM Gear Tooth Precision — Manufactured to exact tooth profile and pitch specifications, ensuring smooth mesh with mating gears and consistent torque transfer.
- Direct-Fit Replacement — Matches the original mounting dimensions and bore geometry of the drive assembly on MQD series diaphragm pumps for straightforward installation.
- Confirmed Fitment — Verified compatible with MQD2H, MQD3H, MQD2HA, and MQD3HA diaphragm pump models.
- Consistent Diaphragm Actuation — A correctly functioning spur gear maintains the precise reciprocating motion that drives the diaphragm; worn or chipped gear teeth cause irregular stroke cycles and reduced pump output.
- OEM Part Number Assurance — Ordering by Multiquip part number 214900000 eliminates the guesswork of cross-referencing and ensures you receive the exact component your pump was built with.
The internal spur gear is a core component of the diaphragm pump's drive train. It meshes with the drive gear to convert rotational engine power into the reciprocating motion that moves the diaphragm back and forth, drawing fluid in and pushing it out with each stroke. When the spur gear wears down or sustains damage, tooth slippage and uneven engagement disrupt this cycle, leading to reduced flow rate, inconsistent priming, and ultimately pump failure if left unaddressed. Replacing the gear with the correct OEM part restores the precise mechanical relationship the pump relies on for dependable fluid transfer.
