Tough conditions call for Grindex drainage pumps

The ideal drainage pump is one that performs reliably in the toughest of conditions, so operators do not need to waste time checking constantly on its performance. The Grindex range from Integrated Pump Technology offers this, and more. T ough pumping applications, such as on mine and construction sites, need a proven range of drainage pumps that are heavy-duty but

offer low total cost of ownership. These characteristics have been well proven in Grindex units. The Grindex range of drainage pumps handles water with abrasive solids up to 12 mm in size, and with high pH values from five toeight. Distributed locally by authorised southern African agent Integrated Pump Technology, Grindex submersiblepumps have a heritage going back over 60 years – with more than 400 000 pumps delivered. Drainage pumps are most suitable when users need to pump large quantities of dirty water, but still need to achieve heads of up to 200 m, or flow rates of up to 350 ℓ/s. These Grindex pumps deliver all that, and conve- nience besides. This is according to Integrated Pump Technology sales manager Jordan Marsh, who says the unique valve on Grindex drain- age pumps enables air cooling of the motor so they can run dry without a problem – and therefore don’t need babysitting. On the small end of this pump range, the Micro, Milli andMini models are all compact, lightweight and ultraportable. The Micro model’s lowpower consumptionmakes it ideal when running on a generator. The Milli looks similar to theMicro, but enables low suction, down to only a fewmillimetres, thanks to the unique non-return valve. Inthemediumsectionof theGrindex range are theMinex, Minette, Minor, Major, Master and Matador. Their revolutionary hydraulic design ensures high wear resistance, which dramatically reduces any performance drop that may result from long-termwear. “With their internal starter, SMARTmotor protector and optional level regulator, these pumps provide fully automatic protection and control without the need for an external starter,” Marsh says. “The soft starter means smoother motor acceleration, thereby pro- tecting the pump while reducing equipment wear and mechanical stress.” There are also two large Grindex drain- age pumps – the Magnum and the Mega. The Magnum, with its high quality and reliable design combinedwith ease ofmaintenance, is relied on for the toughest jobs. Made of cast

iron, the Mega is ideal for operating in deep excavations where very high-head pumping is needed. Designed to handle pH levels from

six to 13, it can also be fittedwith zinc anodes for additional protection. www.pump-technology.com
