lighter base frames, as well as putting less stress on pump parts and the whole pump unit assembly, according to Kamat. In addition, the G pumps are optimized for the use with VSDdriven motors and with diesel engines, allowing them to be run at between typically 20 and 100% of nominal speed. The range retains the advantage of straight-forward maintenance and wear-part replacement seen on earlier Kamat pumps. Kamat's K50000M-5G, five-plunger pump is designed for even more demanding applications. With a maximum power input of 530 kW, the mining version can handle up to 763 liter/minute, and up to 640 liter/minute without the need for booster pressure. Aside from its longwall pumps, Kamat produces pumps for dust-suppression in underground mining, for descaling in foundries, smelters and steelworks, and for high-pressure cleaning. Becker Mining Systems: Underground Infrastructure Expertise Describing itself as a system solution provider of mining infrastructure, with its headquarters in Friedrichsthal, Becker Mining Systems AG sells its products to the leading mining companies around the world. In addition to Germany, it has subsidiaries in France, Poland, Russia, China, South Africa, Australia, the U.S., Canada and Chile. The company claims to be the only worldwide supplier of complete energy distribution, automation, communication and transport systems for underground mining. While its main markets are currently in the coal, gold and platinum industries, 2013 • VDMA MINING SUPPLEMENT its products can be used in all types of mining operations, and are designed to meet the highest demands for use in explosive atmospheres. Becker points out that a safe, flexible supply of energy is absolutely essential in underground mining, and that it offers complete, tailor-made energy infrastructure solutions that yield maximum output, even under the most difficult conditions.Its energy-distribution products include transformers and switchgear that can be handled flexibly and quickly because of the modular technology that it has developed. In the area of automation, Becker offers flexible solutions it says guarantee the comprehensive control and monitoring of all work processes at all levels of a modern mine. This in turn leads to higher efficiency and greater safety, it adds. Communication is an important growth area for the company, which has a range of mobile radio solutions that provide uninterrupted communication throughout an entire mine. Since the company was founded in 1964, Becker has been developing transport systems for men and materials underground. The product portfolio ranges from floor-mounted traprail systems and overhead monorails to chair lifts and pumps. In addition, the company produces hydraulic and mechanical roof-support systems for securing longwall faces and roadways during and after excavation. Becker recently introduced its BRS 2 belt-rip detection system, which it has developed to help increase the productivity of conveyor belts by detecting belt rips as soon and as reliably as possible. The system uses inductive loops that are embedded in the belt. Once installed, it detects the loops on the conveyor, VDMA VDMA 17
