Multiquip 214000001 Crank Machined MQD3H - OEM Replacement Part for Diaphragm Water Pumps

The machined crank converts rotational motion from the engine's crankshaft into the reciprocating movement that drives the diaphragm in Multiquip's high-capacity water pumps. Operating at 60 cycles per minute at maximum engine RPM (2,750), this precision-machined component is essential for maintaining the pump's alternating expansion and contraction cycle that enables pumping capacities up to 90 gallons per minute.

This crank is engineered for Multiquip's diaphragm pump series, which features a maximum suction lift of 26 feet and maximum head of 25 feet. The diaphragm pump design paired with this machined crank allows the unit to handle solids up to 1-5/8 inches in diameter, making it ideal for construction dewatering and debris-laden water applications.

Signs of crank wear include irregular pumping cycles, reduced flow capacity, excessive vibration, or unusual noise during operation. Regular inspection of the crank assembly during routine maintenance intervals helps prevent catastrophic pump failure and costly downtime.
