The Multiquip 2064851 Gear Case Cover is a genuine OEM component designed for MQ diaphragm pump models including MQ-D206H, MQ-D305, D306, and MQ-D306HA. Sourced directly from Multiquip, this cover is built to the exact tolerances of the original part, ensuring a secure, properly sealed fit over the gear case assembly. If your existing cover is cracked, warped, or missing, replacing it promptly with the correct OEM part protects the internal drive components from contamination and wear.
Key Features
- OEM Dimensional Accuracy — Cast and finished to the original Multiquip specification, ensuring the cover seats flush against the gear case housing without gaps or misalignment.
- Direct Drop-In Replacement — Matches the original mounting pattern and fastener positions on MQ-D206H, MQ-D305, D306, and MQ-D306HA diaphragm pumps for a straightforward swap.
- Gear Protection — Fully encloses the gear case to shield internal drive gears and lubrication from debris, moisture, and pumped-media contamination.
- Structural Integrity — Manufactured from the same material grade as the original, resisting the mechanical stress and vibration inherent to diaphragm pump operation.
- Preserves Lubrication Integrity — A correctly sealed gear case cover retains gear oil and prevents premature gear wear that results from lubrication loss or contaminated oil.
The gear case cover encloses the drive gear assembly that translates engine power into the reciprocating motion needed to flex the pump diaphragm. By sealing this cavity, the cover keeps gear lubricant contained and prevents abrasive debris or pumped liquids from reaching the gears and bearings inside. When the cover cracks or is improperly sealed, lubricant escapes and contaminants enter, accelerating gear wear and leading to loss of pumping action or complete drive failure.
