Advanced technology heavy drives are being custom-engineered by Bonfiglioli for clean and robust service in applications where they are mounted vertically to aerate or mix liquids.
One of the latest locally engineered HD drives integrates 55kW six-pole motors with an HDP helical parallel series drive, featuring dry well construction and OP2 lubrication pump.
The motors – specified for 55kW power and 10 kNm torque – incorporated the OP2 lubrication pump to ensure optimum bearing performance in vertical mountings.
They were also epoxy coated for corrosion protection, cleanliness and durability.
The drives incorporate dry well construction to safeguard against oil leaks into process liquids as seals age and wear.
“These particular drives were for aerators at a wastewater treatment plant, but many of the features apply equally well to other process applications involving food and beverage manufacturing or minerals processing liquids,” says the Managing Director, Bonfiglioli Transmission (Australia) Pty Ltd, Mr Malcolm Lewis.
“For example, drive bearings were engineered to accept the greater loads generated when used on the long shafts found in aerators.”
One of the outstanding flexibility features of Bonfiglioli’s new Australasian production and testing line for HD drives is that the company can adapt specific drives to particular applications.
HD drive combinations are particularly suited to conveyor drives and materials handling applications across a wide range of industries, including manufacturing, mineral processing, primary processing, resources, energy and water and waste water, says Mr Malcolm Lewis.
