Electromechanical services provider Marthinusen & Coutts’ Cleveland Engineering Services Division, a division of electromechanical equipment company ACTOM, has teamed up with the Marthinusen & Coutts Kitwe facility, in Zambia, to rehabilitate medium voltage pump motors in one of the wettest mines in Africa.

An original-equipment manufacturer of pumps had approached Marthinusen & Coutts, the largest after-market service provider of electrical and mechanical rotating machines in Africa, to assess several underground pump motors. There was an urgency to the situation owing to the risk of flooding should there be any undue interruptions in pumping operations.

Investigations revealed that the motors driving the pumps were in a poor condition, with this severely affecting the availability and the performance of the pump chambers. This required the initiation of a detailed refurbishment programme, involving the procurement of spare parts, the setting up of an in situ bearings store, and taking the lead in returning the motors to full service.

Where possible, the motors were repaired in situ – thus avoiding any possible crisis of underground flooding – while others were removed for full refurbishment. The highest level of engineering practices were followed during repairs, reinstallation and commissioning.

Ongoing support is also being provided, including the training of mine maintenance staff, the development of installation and commissioning specifications, conducting of regular site inspections, management of spares, and continual engagement with mine engineering management.

Marthinusen & Coutts operates six repair and manufacturing facilities – in Johannesburg, Benoni, Sasolburg and Rustenburg, in South Africa; in Harare, Zimbabwe; and in Kitwe. Supported by a network of technically equipped partners throughout Africa, it provides services not only in Africa but globally.
