Pleuger Industries, the Hamburg-based quality manufacturer of submersible motor pumps, will be exhibiting in the Germany Pavilion of Asia Pacific’s International Mining Exhibition 2019 (AIMEX) from August 27 to 29, 2019.  At this show a new energy-efficient synchronous motor with permanent magnet drive will be presented.

The synchronous motor with permanent magnet rotor has up to 14 % higher efficiency compared to conventional induction motors.  Since 90 % of a submersible motor pump’s life-cycle costs are attributable to power consumption, the latest technology provides enormous power saving potential. The hermetically sealed rotor is also protected against corrosion and mechanical influences and contributes to maintenance-free operation.

At the production site in Hamburg, the R&D department creates tailor-made unique alternatives for mining companies around the world. These include iron ore mines in Western Australia, copper mines in Chile, uranium mines in Niger and opencast lignite mining in Germany.

Pleuger’s pump range includes standard and special units from 4 to 50 inches, depending on the pump operator’s requirements. Pressure jacket pumps that do not require dynamic seals and are therefore considered particularly reliable are used to increase the pressure in pipelines.
