End users increasingly opting for OEM pumps

There is a marked move in the Southern African mining sector towards install- ing OEM pumps. This is according to Colin Adams, MD of Integrated Pump Technology, who says that this recent change in the market has turned the pre- vious trend of sourcing cheaper replicated pumps on its head. “It is always tempting in difficult eco-

under extreme operating conditions and its excellent controllability,” explains Wynand Kellerman, General Manager, HAW. “In addi- tion, the many control positioning options available to the operator eliminate the need to add auxiliary components and additional pipe connections.” Other benefits of the valve include its modular design. “In the case of a malfunc- tioning valve section, this design feature means that only the faulty section needs to be replaced, and this can be done on site without having to remove the entire valve,” Kellerman continues. The VDP08 load sensing valve can be ordered for use with both variable and fixed displacement pump applications.

The high cost of unplanned downtime due to a pump installation that fails can impact directly on the productivity of an operation, and therefore on its profitabil- ity, says Adams. “And this is a scenario that we have seen often over the last few years where end users have purchased pumping equipment that is not engineered to

cope with the harsh African operating conditions,” he continues. Integrated Pump Technology was established as the official Southern African distributor for the Grindex range of elec- trical submersible pumps, and later the company added the Italian manufactured Faggiolati pump brand to its product portfolio. Both are Original Equipment Manufacturer (OEM) pump brands and, as such, have strong legacies when it comes to product research and development. Product development is essential as this includes the incorporation of the lat- est hydraulic technologies and materials of construction to ensure that pumps will meet operational requirements. This is something that maintenance personnel on mines are fully cognisant of and this knowl- edge needs to be transferred to buyers and management whomay not always consider the performance and reliability approach when making the purchasing decision. An example of technology being lever- aged in Grindex pumps is the unique air valve that has been integrated into the dewatering pump range. This allows the impeller to pass air instead of water past the motor in a dry run condition. Another feature in the dewatering range which ensures optimal operational performance is the patented SMART motor protector which provides thermal overload, phase loss and phase rotation protection. The Grindex sludge range has all the advantages of the dewatering range cou- pled with a recessed vortex impeller and split hydraulics with replaceable rubber linings. This makes these pumps capable of greater solids handling with increased abrasion resistance. Integrated Pump Technology, tel (+27 11) 918-9034

Grindex pumps have a proven track record in dewatering.

Cost-effective load sensing valve introduced Hydraulics & AutomationWarehouse (HAW) recently introduced the SALAMI VDP08 load sensing valve to the hydraulic industry. The valve is said to be ideal for a wide range of applications, mainly in the mobile field, where independent flow control of actua- tors is needed without being affected by load variations.
