Agitators, Mixers, Aerators and Thickener

The drives used for Agitators, Aerator and Thickener applications require careful selection as many need very low speed, high torque, limiting torque and often have external forces or loads acting on the gear unit shaft or casing which must be catered for.

Technidrive have a wealth of experience in this industry and can work with customers to ensure correct drive selection is achieved to provide required performance, efficiency of the process and longevity of the drive system.

Gear unit can be selected to suit virtually any mounting position required for these applications.

Waste Water Screens & Compactors & Dissolved Air Flotation Applications

Waste water screens and compactors use a variety of drive designs and the gear unit often has to cater for the trust loads caused by the screw.

Technidrive work with customers to make sure the drive is selected correctly and operates for the design life.

Driver Replacements

In addition to calculations and drive selections for new applications Technidrive also specialise in unit replacement.

These often require application specific mounting plates, flanges and couplings along with gear unit upgrade to increase service life
