Drive control for pumps and ­agitators

September 2018 Motion Control & Drives

Nord Drivesystems, designed by German precision engineers Getriebebau Nord, and assembled locally by BMG, encompass efficient drive configurations to ensure optimum performance of mechanical speed control for specific applications, in almost every industry.

“Nord drive solutions, which meet stringent local and international quality standards, are known for reliability, energy-efficiency, low noise levels, extended service life and reduced maintenance,” says Mark Barbour, business unit manager electromechanical division, BMG. “These modular systems incorporate advanced drive technology and special design features to meet the exact requirements of every operation. In the processing sector for example, Nord Drivesystems are engineered with reinforced bearings and increased bearing spacing, especially for agitator, pump and mixer applications.

“Reinforced and larger output shaft bearings allow the gear unit to absorb the high radial and axial bearing loads that occur during the agitating process. An important benefit of this design is the extended service life of the gear units.”

To enhance efficiency, an agitator version (VL2 bearing) with increased bearing spacing and reinforced bearings, as well as a drywell version (VL3) with an additional oil drip plate and leakage or oil sensors, are available from BMG. The bearing spacing of VL2 and VL3 versions is increased with attachments, while the gear unit size remains unchanged.

Advantages of large oversized output bearings include quick assembly, large bore capacities, high radial load capacity and extended service life.

Modular Nord Drivesystems are easy to expand or upgrade, using a minimum of different types and sizes of components. Local assembly enables prompt delivery of drive and readily availability spare parts.

Included in BMG’s Nord range are drives for torques from 10 Nm to over 250 kNm, electric motors in the power range from 0,12 kW to 1000 kW and frequency inverters with the required power electronics up to 160 kW. Inverter solutions are available for conventional control cabinet installations, as well as for decentralised, fully-integrated drive units.

BMG has made a substantial investment to ensure assembly and spares holding are in line with international standards. A team of technicians with extensive experience in gearing offers a technical advisory and support service tailored to meet the precise specifications of contractors, designers and end-users.
