Bridge-Mounted Dual Drive

Used in industrial, municipal, and mining clarifiers and thickeners.

The DBS Bridge-Mounded Dual Drive has two concentric output shaft drives: the rake drive and the turbine drive. The rake drive section has a rotating flange hub with attachment points for the output shaft. The gear drive is low-speed, high-torque, and totally enclosed. It is also designed with positive overload protection. The turbine drive section is a heavy-duty, totally enclosed gear drive that runs at a higher speed. A variable speed turbine drive is standard. The Bridge-Mounted Dual Drive is supported by a bridge that extends across the length of the tank. It is typically used on tank sizes from 10 ft to 100 ft (3 to 30 m) in diameter.

The main gear and pinion are made from forged alloy steel designed for 20 years of life (calculated per AGMA 2001-D04). The precision, four-point-contact main bearing comes with a 10-year warranty. Each unit is designed for minimum maintenance with permanently lubricated rake intermediate gearbox and dry well lubrication on turbine output.

An accurate torque gauge is integrated into every unit and can be calibrated in ft-lbf, N-m, or any units desired. This model also includes alarm and cutoff switches and maximum torque limiting via shear pin or pressure relief valve.

Bridge-Mounted Dual Drives are commonly used in the mineral processing, power, and pulp and paper industries.
