Multiquip 0203050002 Friction Disc - OEM Replacement Part for Submersible Pumps

The friction disc is a critical wear component in the mechanical seal assembly of submersible pump systems, providing precise surface contact and sealing pressure to prevent oil leakage from the dual silicon carbide mechanical seal chamber. This disc works in conjunction with the oil-bathed seal system to maintain the 180cc oil capacity that protects the motor bearings and seal faces from water intrusion during continuous submersible operation.

Designed for the ST3050D 3-inch submersible trash pump, this friction disc operates under demanding conditions including maximum submergence depths of 32.1 inches, pumping capacities up to 264 gallons per minute, and liquid temperatures up to 104°F. The dual mechanical seal system protected by this component is essential for the pump's ability to handle solids up to 2 inches in diameter while maintaining reliable performance at 3,550 RPM motor speed. Regular inspection of friction disc wear is critical during routine mechanical seal maintenance, especially in applications involving construction site dewatering, excavation drainage, and well casing operations where grit and debris can accelerate seal component degradation.
