Multiquip 1936FS0750N Bearing Bracket - OEM Replacement Part for Submersible Pumps

The bearing bracket provides critical structural support for the motor shaft assembly in Multiquip ST-series submersible pumps, serving as the mounting interface between the pump casing and seal bracket. This component works in conjunction with the dual mechanical seal system (lower silicon carbide vs silicon carbide, upper carbon/ceramic) housed in the oil-filled chamber, ensuring proper alignment and support during high-capacity pumping operations.

During impeller removal and seal maintenance procedures, the bearing bracket must be accessed by removing the four bolts and lock washers that secure the pump casing to the seal bracket assembly. This bracket maintains precise motor shaft alignment critical for the dynamically balanced chrome steel impeller, which operates at maximum capacities of 423 gallons per minute and heads up to 138 feet. Proper installation of this bracket is essential for preventing premature wear on the dual mechanical seals and maintaining the oil chamber integrity that protects against seal failure in demanding industrial conditions.

Compatible with the following Multiquip submersible pump models:

• ST41230 (4" discharge, 230V three-phase)
• ST41460 (4" discharge, 460V three-phase)
