The Multiquip 335412000 Output Gear is a genuine OEM component designed for MQD2H, MQD3H, MQD2HA, and MQD3HA diaphragm pumps. Sourced directly from Multiquip, this output gear meets the exact specifications of the original part installed at the factory. If your diaphragm pump is exhibiting drive irregularities, loss of pumping rhythm, or visible gear wear, replacing the 335412000 is a direct path back to correct operation. DHS Equipment stocks this part so you can get your pump back in service without extended delays.
Key Features
- Genuine OEM Gear Tolerancing — Machined to the precise tooth profile and hardness spec of the original, ensuring smooth mesh and consistent torque transfer through the drive train.
- Direct Drop-In Fitment — Matches the original mounting interface and gear geometry, so installation seats correctly without modification to the gear housing or shaft.
- Confirmed Compatibility — Verified fitment for MQD2H, MQD3H, MQD2HA, and MQD3HA Multiquip diaphragm pump models.
- Sustained Pumping Cadence — A properly functioning output gear delivers consistent rotational force to the diaphragm drive mechanism, maintaining steady flow rate and pump output pressure.
- Long Service Life Under Load — OEM gear material and heat treatment resist wear even under the continuous cyclic loading that diaphragm pump operation demands.
The output gear is a core drivetrain component in a diaphragm pump's mechanical drive system. It transfers rotational power from the engine or motor to the eccentric mechanism that drives the diaphragm back and forth, creating the pumping action. When the output gear wears or loses tooth integrity, the drive becomes inconsistent, resulting in reduced flow, irregular pumping stroke, or complete loss of pump function. Replacing a worn 335412000 Output Gear restores the correct mechanical link between the power source and the diaphragm, returning the pump to full rated performance.
