Multiquip 1992000110 Volute Casing Closed 4 Post - OEM Replacement Part

The volute casing is the core housing component of your Multiquip trash pump that converts the rotational energy of the impeller into fluid pressure and directs water flow from the suction inlet to the discharge port. This closed 4-post design features integrated mounting points for the clean-out cover assembly, allowing quick access to the pump cavity for debris removal and maintenance. The volute's engineered shape is critical for maintaining the QP3TB series pump's 396 gallons per minute maximum capacity and 95-foot maximum head performance specifications.

This genuine OEM volute casing is designed specifically for 3-inch trash pump applications, accommodating solids up to 1.50 inches in diameter. The four-post configuration provides secure mounting for the locking knobs and clean-out cover system, which is essential for routine inspection and clearing of debris that can accumulate during high-volume pumping operations. Proper volute integrity is critical for maintaining the pump's maximum suction lift of 25 feet and preventing performance loss.

Compatible with the following Multiquip pump models:

• QP3TB
• QP3THX
