The Multiquip 214000090 Crank Assembly Kit is a genuine OEM component designed for MQD2HA and MQD3HA diaphragm pumps. As an authorized Multiquip replacement part, it is manufactured to the same specifications as the original, ensuring a direct, compatible fit in your pump's drive mechanism. This kit covers everything needed to restore the crank system on MQD2HA and MQD3HA models, keeping your pump running at full output capacity.
Key Features
- Genuine OEM Construction: — Machined and assembled to original Multiquip tolerances, delivering the correct stroke geometry and load capacity critical to diaphragm pump operation.
- Complete Kit Format: — Includes all crank assembly components needed for a full service replacement, so you are not sourcing individual pieces separately.
- Confirmed Fitment: — Engineered specifically for Multiquip MQD2HA and MQD3HA diaphragm pump models — verify your model code before ordering.
- Restores Full Pump Output: — A worn or damaged crank assembly causes loss of diaphragm stroke, reduced flow rate, and uneven pumping cycles; this kit brings output back to specification.
- Durable Drive Components: — Built to withstand the repetitive eccentric load cycles that diaphragm pump cranks experience during continuous operation on demanding jobsites.
The crank assembly is the mechanical heart of a diaphragm pump, converting rotational engine power into the reciprocating motion that drives the diaphragm back and forth to move fluid. Without a properly functioning crank, the diaphragm cannot maintain a consistent stroke, leading to reduced flow, pressure loss, and eventual pump failure. Replacing a worn crank assembly with a genuine OEM kit restores the correct stroke length and ensures the diaphragm operates as intended across the full duty cycle of the pump.
