The Hoshizaki 433522-01 Modular Crescent Cuber Pump Impeller restores proper pumping performance within compatible ice-making systems. This precision-shaped rotating component mounts to the pump assembly and uses its vane geometry to move water through the circulation path at the required flow rate. By maintaining consistent water movement across the evaporator surface, the impeller supports uniform ice formation and dependable harvesting cycles. Its construction is suited to the wet, repetitive operating environment of commercial ice machines, withstand routine service demands and continuous circulation. Replacing a worn or damaged impeller can improve pump efficiency, stabilize water delivery, reduce operational interruptions, and maintain consistent ice production during demanding foodservice applications.
