Multiquip 6391651004 Driven Coupling DPS90SSJ

The Multiquip 6391651004 is a genuine OEM Driven Coupling DPS90SSJ designed for the DPS-90SS submersible pump. As a direct OEM replacement, this coupling is manufactured to the same specifications as the original component, ensuring a correct installation with no fitment guesswork. Verified for the DPS-90SS, this part gives you confidence that you are installing exactly what the machine was built with. Order from DHS Equipment for fast fulfillment of genuine Multiquip parts.

Key Features

• Genuine OEM Construction — Manufactured to the same coupling tolerances and material grade as the original DPS90SSJ component, maintaining correct torque transfer characteristics throughout the drivetrain.
• Direct-Fit Installation — Engineered to align and connect exactly as the original driven coupling, so installation proceeds cleanly without reworking mounting interfaces.
• Confirmed DPS-90SS Fitment — Sourced specifically for the Multiquip DPS-90SS submersible pump; reference part number 6391651004 to confirm compatibility before ordering.
• Restored Drive Efficiency — A correctly functioning driven coupling transfers rotational force from the motor to the pump impeller without slippage or vibration; a worn coupling causes power loss, erratic flow, and accelerated wear on surrounding components.
• Extended Service Life — OEM-grade materials resist the mechanical stress and moisture exposure typical of submersible pump operation, holding up through demanding dewatering and transfer applications.

The driven coupling is the mechanical link between the motor shaft and the pump's impeller assembly, transmitting rotational energy to generate flow. When this coupling is intact and correctly seated, the pump delivers consistent output and smooth operation. As the coupling wears or fractures, drive engagement becomes inconsistent — resulting in reduced pumping performance, unusual vibration, and potential damage to the motor and impeller if left unaddressed.
