High efficiency motors for water treatment

1 April 2020 Electrical switching & drive systems & components

The arduous operating conditions at water treatment plants mean that the motors must be highly efficient and IP65 rated for corrosion resistance. This is where Bauer motors come into their own. Applied mainly to drive pumps and aerating impellers, the Bauer range for the water treatment industry features IE2, IE3 AND IE4 energy efficiency, in addition to an IP65 rating and Class H insulation, with flange-mounted vertical and horizontal options.

Apart from the motors themselves, gearboxes also have to be IP65 rated, in addition to having a special corrosion resistance coating to protect the motor casings and shafts by ensuring adequate lubrication of all internal components.

Chain products used in water treatment plants are mainly stainless steel for added durability, apart from the mild steel sprockets themselves. Bearings International (BI) is able to supply a complete solution for water, sewage and effluent plants, including couplings, pulleys and belts, gearboxes and bearings.

Other BI products ideal for the waste treatment industry are the smaller TR inline gearboxes, which are ideal to drive reticulation pumps, clarifiers, and raw water pumps. The Bauer range even includes a two stage gearbox for larger aerators.

A major advantage for BI is that it carries stock of all the above-mentioned products. “BI offers the wastewater treatment segment cost-effective solutions from a one stop supplier. All our premium brand products are also backed up with performance guarantees,” says chains and gears product manager, Frikkie Ras.
