Drive Units for the Wastewater and Water Treatment Industries
DBS Manufacturing drive units work effectively in many wastewater and water treatment processes. Our products produce consistent rotation speeds in all environments while minimizing energy consumption. In addition, our engineers focus on increasing reliability while reducing required maintenance, saving your company time and money over the life of the product. Drive units power a wide variety of water and wastewater treatment activities including primary and secondary sludge clarifiers and thickeners, wastewater grit hydro-separators, oxidation ditches, anaerobic flocculation, and trickling filtration.
Our flexible, customer-first engineering process ensures you get a component that will work for your industry and your specific processes. Our standard products work on a wide variety of components, and we can easily modify standard design drives to give you an optimal component at a reduced cost.
Torque Gauge
The DBS large-diameter, stainless steel gauge accurately shows the drive unit’s torque in Newton-meters or foot-pounds. Other manufacturers use percentages or color systems, but with DBS you get the exact numbers you need to determine unit performance. For remote torque monitoring and process control, you can add an optional 4-20 mA torque transducer.
Bridge-Mounted Aerator
Used in oxidation ditches
The DBS NSA Bridge-Mounted durable Aerator is cost competitive with high-speed aerators while offering the efficiency and power savings of low-speed aerators. Power savings can be significant, around 20% to 30% or more. The planetary gearbox is mounted directly in the aerator rotor. A high-efficiency, backwards-curved radial blade rotor increases oxygen transfer efficiency.
Bridge-Mounted Drive
Used in primary and secondary clarifiers and thickeners
The DBS Bridge-Mounted Drive is a low-speed, high-torque, totally enclosed gear drive with positive overload protection. The drive unit has a central output shaft to drive the rakes, and is supported by a bridge completely spanning the tank. It is typically used on tank sizes from 10 to 100 ft (3 to 30 m) in diameter.
Bridge-Mounted Dual Drive
Used in primary and secondary clarifiers and thickeners
The DBS Bridge-Mounded Dual Drive has two concentric output drive drums: the rake drive and the turbine drive. The rake drive section has an external rotating drive drum with attachment points for the rake cage. 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.
Floating Aerator
Used in lagoon aeration
The DBS NSA Floating Aerator is a low-speed aerator. This durable aerator combines the efficiency and power savings of low-speed aerators with the affordability of high-speed aerators. Power savings can be significant, in the range of 20% or more.
A planetary gearbox drives the aerator rotor. This mass-produced gearbox provides the DBS NSA Floating Aerator with its impressive power/cost ratio. Choose from a traditional high-efficiency backward-curved radial blade rotor or a DBS dynamic draft tube rotor.
Grit Chamber Drive
Used in wastewater grit hydroseperators
DBS manufactures custom drives for applications such as flocculators, mixers, vacuum filters, rotating biological contact units, and other industrial applications. Our grit chamber drives allow the flow in your grit chamber tanks to properly slow.
Hyperbolic Mixer
Used in anaerobic flocculation
The DBS Hyperbolic Mixer rotor is specifically designed to operate at the bottom of a mixing basin where the rotor will efficiently draw water down and discharge it in a horizontal direction. This induced flow will circulate the water in the tank from bottom to top to maintain all solids in suspension. DBS Hyperbolic Mixers are available in configurations from 1 HP (0.75 kW) to 30 HP (22 kW). We also build custom Hyperbolic Mixers for industrial applications.
Mixers and Flocculators
Used in flocculation, suspension, homogenization, and subsurface aeration
DBS Manufacturing provides custom solutions for many unique flocculator and mixer applications for a variety of industries. Flocculators, agitators, and mixers are made for OEM applications and to retrofit existing equipment. They are easy to install and require minimal maintenance.
All DBS Manufacturing mixers and flocculators are powered by high-efficiency, severe-duty, inverter duty-rated electric motors up to 100 HP. They also come with high-efficiency, severe-duty gear reducers with a high service factor for reliable, long life.
Pier-Mounted Drive
Used in primary and secondary clarifiers and thickeners
Most frequently used as a clarifier drive, the DBS Pier-Mounted Drive is a low-speed, high-torque, totally enclosed gear drive with positive output torque overload protection. The drive unit has an external rotating drive drum with attachment points for the rake cage. It is supported by a column in the center of the tank, and tank sizes typically range from 40 ft to 300 ft (12 m to 100 m) in diameter.

The drive unit has an external rotating drive drum with attachment points for the rake cage. It is supported by a column in the center of the tank, and tank sizes typically range from 40 ft to 300 ft (12 m to 100 m) in diameter.
Rake-Lifting Mechanism
Used in blast furnace scrubber recyclers, BOP thickeners, hot strip mill recyclers, scrubber recyclers, water recyclers, coal fines tailings thickeners, and paste thickeners
Almost all DBS drive units can be provided with a lifting mechanism that can raise and lower the rakes up to 36 inches (900 mm). Rake lifts operate by raising the output shaft into the drive unit on S-series models and raising the entire drive unit on D-Series models. The lift mechanism is fully contained within the drive unit.
Rotary Distributor Mechanism
Used in trickling filtration
DBS Rotary Distributor center mechanisms are available in 2, 3, 4, or 6 arm configurations as a rotary reaction type (hydraulically driven) or motorized type (motor driven). They can be constructed using stainless steel or aluminum. DBS Rotary Distributors are designed for all standard influent pipe sizes from 8 inches to 48 inches (200 mm to 1200 mm).
