:: Refurbished Flotation Wear Components Save Costs
With a cradle to grave approach to flotation components, it is no surprise that Multotec Flotation is actively involved in the refurbishment of flotation wear components.
Craig Walters, product manager at Multotec Flotation, says there is a definite trend towards refurbishment of flotation wear components such as rotors, stators, impellers and diffusers. He attributes the increase in this sector of the market to the significant cost savings being realised as refurbished components cost between 20 to 25% less than new flotation wear components.
Explaining the company's cradle to grave business philosophy, Walters says that flotation wear components generally comprise an inner steel part or carcass around which the polyurethane is cast or moulded.
"Generally refurbishment refers to the restoration of a component from a worn out state back to its former optimum working condition," Walters says. "In the case of polyurethane coated components this means replacing the old polyurethane with new polyurethane in the correct form."
At Multotec Flotation the polyurethane is removed by mechanical means and the steel carcass inside becomes exposed. It is cleaned, treated and repaired if this is deemed to be necessary. The steel carcass is then inserted into the applicable production casting moulds which form or shape the polyurethane to specification.
The refurbished components are subjected to the stringent quality testing throughout the process in accordance with Multotec Flotation's ISO 9001:2000 accreditation. The Multotec Group is in the process of becoming ISO 14001 accredited which envelops the cradle to grave concept.
