Grundfos South Africa will have something new to show attendees at the upcoming Electra Mining exhibition in Johannesburg next month, with the launch of a new generation of its CR inline multistage pumps.

The Grundfos CR pumps will increase efficiency and maximum working pressure while almost doubling maximum flow to 320 m³/h, the company said.

Grundfos will also introduce three extra-large flow sizes based on extensive research, development and testing of new hydraulic designs. These have been engineered using state-of-the-art production methods, including a fully automated and flexible production line, it said.

Niren Rohanlal, Lead Business Development Manager at Grundfos, Sub-Saharan Africa, said: “The new CR will significantly move the limits for energy efficiency, which is extra-important when
you are working with large pumps. The increases to maximum working pressure and flow will also mean that the new generation can be used even more widely.”

The new 40 bar standard working pressure is suited to applications like filtration, reverse osmosis and boiler feed, Grundfos said. “And, with its increased 320 m³/h flow capacity, the CR will even be able to take on high-flow applications – such as large waterworks – which have until now been served by other pump designs,” the company added.

Grundfos will be unveiling the new generation of pumps at its stand, H31, in hall six of the Expo Centre Nasrec on September 11 at 11am.
