BMG’s solutions for the water, wastewater and sewage sectors, encompass the supply of quality branded drive systems, which are enhanced by the BMG team’s technical expertise and installation, condition monitoring, maintenance and engineering support capabilities.
“BMG specialists – with technical knowledge and extensive experience in water engineering – play an important role in upgrading ageing water and wastewater facilities and designing new drive systems, to ensure a dependable infrastructure,” explains Mr Kelly Mac Iver, Gears Business Unit Manager, BMG ElectroMechanical Division. “The selection of robust equipment, which can endure continuous operation under severe conditions is critical.
“It is also important to prevent unnecessary breakdowns, which is why reliability is our main focus when designing the drive systems for new and upgraded facilities. All BMG components are precisely matched to each other and to application requirements, to ensure high productivity, smooth operation and long service-life. Apart from the supply of new drive systems, the company’s broad branch network offers original spares and advanced workshop resources that ensure all repairs to drive components meet pristine OEM standards.”
BMG supplies an extensive range of drive packages from NORD DRIVESYSTEMS and Sumitomo Drive Technologies (Hansen, Paramax, Cyclo, HSM helical shaft mounts) which have been designed especially for optimum efficiency in harsh applications, including water, wastewater and sewage treatment plants.
Sumitomo’s Hansen product range includes gear units that drive aerators, water screws and brush aerators.
The internal construction of the gear unit housing allows for simple and complete oil drainage, while Hansen’s Oil-Lock and Oil-Guard systems offer a maintenance-free sealing on high-speed shaft extensions. The drywell – available on Hansen P4 gear units – prevents oil leakage on vertical down shafts. Larger units, with inspection covers above the oil level, allow for convenient inspection of internal components on site.
Standard application designs range from 13 kNm to 328 kNm torque capabilities.
BMG’s Sumitomo Paramax gear reducers, which are proven in the conveyor and materials handling industry, also offer the water treatment sector a range of gearboxes.
This range is available as right angle or parallel vertical units, with a 25 degree pressure angle tooth form, that produces stronger gearing. The mechanical oil pump requires no electricity; gears are carburised, heat-treated and finished to the highest standards of accuracy.
“NORD drives consist of gears, motors and brakes that are protected against corrosion. Special covers for the hollow shaft and motor also ensure that the drive is entirely resistant to spray from tanks and the humid and aggressive conditions to which it is exposed in sewage treatment plants,” says Deon Crous, National Product Manager, NORD Drive Systems at BMG.
A feature of these drives is the Unicase gearbox that accommodates all bearing seats within a rigid one-piece casting – no bearing seats are located on bolt-on flanges or covers. Sealing surfaces are not subjected to torque stress or overhung loads and hardened wheel bodies with specially treated teeth, ensure smooth and quiet operation at maximum load capacity.
BMG has made a substantial investment to ensure assembly, stockholdings and technical back-up for its comprehensive range of industrial geared motors. All gearboxes and electric motors are in keeping with international standards. This facility enables the quick delivery of world-class geared motor solutions in selected African countries. Full repair and maintenance services are also offered.
