Bauer motors for water treatment plants
July 2019
Motion Control & Drives
According to Bearings International (BI) electric motors product manager Lewis Hiepner, the arduous operating conditions at water-treatment plants mean that the motors specified not only have to be high-efficiency, but must also be IP65-rated for corrosion resistance. This is where Bauer motors come into their own, applied mainly to drive pumps and aerators. 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. BI chains and gears product manager Frikkie Ras explains: “We are able to supply a complete solution for water, sewage and effluent plants, including couplings, pulleys and belts, gearboxes and bearings, which ensure that such plants operate optimally and with minimal downtime.”
Highly-engineered chain products for water-treatment plants cater for different pitch sizes and construction materials, including grades 314 and 316 stainless steel. Here the most common sizes used are three-, four- and six-inch chain. Other BI products ideal for the water-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.
“What gives BI the leading edge in the water-treatment industry is not only the premium product range we supply, but the fact that we offer free plant inspections and maintenance checks to ensure that the products are installed and applied correctly for maximum efficiency,” adds Ras.
BI also has a dedicated water industry specialist to provide technical advice and help customers to resolve specific problems or issues, as well as optimise existing facilities with the latest equipment.
“We are able to visit a plant to assess its specific requirements, which forms the basis of a complete solution,” concludes Ras. “Product training is also provided for plant engineers, workshop foreman, or general staff, which goes a long way to assist with preventative maintenance.”
