Tough conditions call for Grindex drainage pumps so they can run dry without a problem – and therefore don’t need babysitting.

The ideal drainage pump is one that per- forms reliably in the toughest of conditions, so that operators do not need to waste time checking constantly on its performance. The Grindex range from Integrated Pump Technology offers just this, and more. The Grindex range of drainage pumps handle water with abrasive solids up to 12 mm in size, and with high pH values from five to eight. Distributed locally by autho- rised southern African agent Integrated Pump Technology, Grindex submersible pumps 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 litres a second. These Grindex pumps deliver all that, and convenience besides. This is according to Integrated Pump Technology sales manager, Jordan Marsh who say the unique valve on Grindex drain- age pumps enables air cooling of the motor

933 projects this year. They commented: “GHH creates excitement with a more sleek and sophisticated look than we’re used to seeing in this category. The opera- tors’ compartment is comfortable and ergonomically designed and there are a number of excellent safety features (mul- tiple fire extinguishers, low slip surfaces and strong LED lighting). The fact it also has best in class power, turning radius and tipping angle indicates a clear focus on designing a product that sets new class standards. Overall, this is a really impres- On the small end of the range – com- prising the Micro, Milli and Mini models – these pumps are compact, lightweight and ultraportable. The Micro model’s low power consumption makes it ideal when running on a generator. The Milli looks sim- ilar to the Micro, but enables low suction down to only a few millimetres, thanks to the unique non-return valve. In the medium section of the Grindex range are the Minex, Minette, Minor, Major, Master and Matador. The revolution- ary hydraulic design ensures high wear resistance and dramatically reduces any performance drop that may result from long-time wear. “With their internal starter, SMART motor protector and optional level regulator, these pumps provide fully automatic protection and control without the need for external starter,” Marsh says. “The soft starter means smoother motor acceleration, thereby pro- tecting the pump while reducing equipment

sive example of design and engineering and a standout project.” GHH presented the MK-42 a year ago. The prime dump truck in the manufacturers product range carries 45 tonnes of payload with a volume of up to 24 m³. The economic aim during development was high produc- tivity paired with low operating costs, told GHH. Indeed, if you put a lot of effort into it, you almost inevitably create a result that exudes recognisable competence. A clear design has become kind of a trade mark for GHH: everything is exactly where you can find it immediately, even in the harsh and hectic daily routine.  There are two large Grindex drainage pumps – the Magnum and the Mega. The Magnum is relied on for the toughest jobs, with high quality, reliable design combined with the ease of maintenance. 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 fitted with zinc anodes for extra protection.  Grindex drainage pumps offer heavy-duty performance at low total cost of ownership. wear and mechanical stress.”

The MK-42 dump truck from GHH has been well received in the market. Design prizes such as the Red Dot and, most recently, the Good Design Award show that even aesthetes are impressed. The award from Good Design Australia came as a surprise to the German machine manufacturer. The MK-42 had taken part in the competition for 2021. Australia is one of the most important markets for GHH, one of the leading brands of heavy machinery for mining, tunnelling and special civil engineering.
