[7 January 2013] Clean water with flexible communication

Producing drinking water can be a complicated process, but in Halmstad on the Swedish west coast, it is surprisingly easy. In fact, the groundwater from the eskers of Halmstad is so clean that it is possible to use it directly as drinking water.

[29 June 2005] Providing flush pumps with flow control

The flush pump system at the Lith drinking water production plant, a division of Brabant Water, recently underwent an overhaul. This system comprises two 55 kW centrifugal pumps driven by electric motors. They produce a combined output of 0 – 2000 m3/hour

[29 June 2004] Great savings through improved pump control

Extended service life for the high-pressure pump, no need for motor-operated valves plus reduced pipe-installation dimensions all contribute to savings of over SEK 50,000 when renovating a pump in a pump station.
