Multiquip 1036FS0750N Pump Casting - OEM Replacement Part

The pump casting is a critical structural component that houses the impeller and sealing assembly in centrifugal submersible pumps, providing the pressure chamber necessary for efficient water displacement and flow. This cast iron component features precision-machined surfaces to maintain proper tolerances for the chrome steel impeller and double mechanical seal system, ensuring reliable performance in high head applications up to 138 feet and flow rates up to 423 gallons per minute.

Designed for the ST Series 4-inch submersible pumps, this casting works in conjunction with the rigid stainless steel outer casing to provide structural strength and maximum cooling effect on the 10 HP motor. The casting includes the integrated 4-inch NPT male discharge port threading and maintains the narrow 12.48-inch overall diameter required for fitting into 14-inch pipes and well casings. Replacement may be necessary when experiencing seal leakage, impeller wear, or structural damage from debris exceeding 0.6 inches in clear water applications.

Compatible with the following Multiquip models:

• ST41230 (230V Three-Phase)
