ELECTRA MINING AFRICA REVIEW

SEW-EURODRIVE’s growing local range drives entry into new markets As its exhibition presence at Electra Mining Africa showed, SEW-EURODRIVE is rolling out an even greater selection of planetary drives as part of its strategy to ‘close the loop’ in its product offerings by expanding into more industry sectors. A mong the new ranges being introduced into South Africa are its SEW PPK series and the SEW P2.e series of planetary gear units – both showcasing new opportunities for industrial gearbox users. According to Jonathan McKey, 124 kNm with ratios from 15,2:1 to 332:1. “The SEW PPK satisfies the need for a lower torque requirement, and is well suited to southern hemisphere

markets,” he explains. The ratio can be further reduced by the addition of a primary reducer before the planetary head, to reach ratios up to 10,650:1 – for a much lower speed capability. The SEW P2.e was then developed with all these benefits, but with a broader spectrum of diversity in its speed – up to 100 rpm – as well as in ratio and torque, he says. While most planetary gearboxes have a three-stage design, the SEW P2.e can also be supplied in a two-stage model. Greg Lewis, SEW-EURODRIVE Business Development Manager for Projects, points out that the company has been careful to retain the same critical dimensions as previous SEW P-series models. This allows customers to migrate seamlessly to the more versatile SEW P2.e units without altering their operating environment or infrastructure. Among the common applications in the mining sector for planetary gearboxes, says Lewis, are clarifiers, thickeners and

National Sales and Marketing Manager at SEW-EURODRIVE, these new additions to the local range highlight the company’s global engineering and applications capabilities. “The PPK series was originally developed by SEW EURODRIVE in Brazil, for instance, to serve their large and thriving sugar sector,” says McKey. “Our design and engineering experts in Germany then further leveraged these advances when they developed the SEW P2.e series – aimed at larger applications.” He emphasises that both series built upon the key benefits that planetary gear units present to customers: a compact solution for space-constrained conditions, alongside high torque and low speed outputs. The SEW PPK series delivers 10 to 18 kNm of torque with a ratio range from 65:1 to 390:1, while the SEW P2.e series encompasses torque ratings from 24 to
