The environmental consequence of mining in South Africa is a well-documented concern to the industry, often leading to the implementation of the ISO 14001 environmental management system.

The increase in demand for stainless-steel submersible pumps, for reasons related to environmental management, has resulted in his company designing and manufacturing a full range of these pumps, reports Hazleton Pumps marketing director Johan de Jager. The company’s Hippo stainless-steel range includes pumps ranging from 2,2 kW to 185 kW. These pumps can be used in slurry and dewatering applications. “In the standard format, the materials that are used are 316 stainless steel for the motor housing, and CD4MCu duplex stainless steel for the wet end.

“The duplex stainless steel provides improved wear properties when compared to 316 stainless steel,” says De Jager.

Since the company embarked on its stainless-steel submersible pump project, pumps of different models have been supplied to Sasol, Ingwe, Anglo Coal and Kumba Resources. The Hippo submersibles are also manufactured in other corrosion- resistant materials, such as Hasteloy, casted by local foundries.

Driven, in turn, by the application need for a heavy-duty, non-clog, solids-handling slurry pump, the manufacturer has also initiated the development of a range of Hippo Vortex vertical-spindle pumps.

“A range of eight models is envisaged at this point, although there are virtually no limits as to what can be achieved,” says De Jager.

The bearing configuration of the pump is based on the design principle that was used on the Hippo VN range of spindle pumps. “The completed models that are already in operation include the 2-10VNR, 3-11VNR and 3-14VNR. “These pumps have the ability to handle 50 mm and 75 mm solids, and models with solids-handling capabilities of 100 mm and 150 mm are currently in the pipeline, with production planned for the end of this year,” notes de Jager.

The company has recently been recognised for its various innovations.

All aspects of the company’s business were audited by a panel of specialists under the guidance of the CSIR when it was entered into the Business Day Technology Top 100 Business Awards, and the Sunday Times Small Enterprise Awards. “Besides achieving the Business Day Technology Top 100 Business Award, the company also won the award for the Sunday Times Best Small Enterprise in Gauteng, the award for Technology Excellence, as well as the Department of Trade and Industry (DTI) Manufacturing Excellence Award,” says De Jager. He tells Mining Weekly that the main factor contributing to the company’s success has been its development and manufacture of the world’s largest vertical spindle froth pump that was manufactured for a phosphate-mine in Russia.
