SEPAC designed the Multiple Disc Wet Clutch (ERD Series) to deliver a reliable, consistent torque within an oil atmosphere. This model offers a ball bearing-supported design to ease the installation process without relying solely on the customer for bearing support. The ERD Series is virtually maintenance-free under proper operating conditions as most of the components are hardened.

The ERD’s design allows the clutch to automatically compensate for wear of the disc pack ensuring long life and the ease of installation make it ideal for a variety of applications. The unique disc design also reduces drag, as well as wear when operating de-energized. Additionally, the extraordinary reliability of the ERD Series makes it a top choice for fan clutches used in heavy and/or armored vehicles, motion control for flight system actuators, critical door operating actuators in industrial plants, or heavy duty machinery.

The magnet body of the ERD is typically installed on a motor or gearbox shaft with the option for a hub, coupling, gear, pulley or sprocket mounted to the spider or clutch cup. When current is applied to the coil, magnetic flux flows through the discs to the armature, which causes the outer discs to be squeezed between the inner discs, which transmit torque from the rotor input to the spider output. The magnet body of the ERD is held stationary by the means of an anti-rotation screw or post anchored to a hole provided. Coils are fully encapsulated in epoxy protecting them from the oil and/or harsh environment the clutch may be subjected to and a sealed connector is standard.
