Danfoss piston pumps run for 23,000 hours with almost no wear Danfoss piston pumps run for 23,000 hours with almost no wear

Residents of Elbow Cay, Bahamas rely on reverse osmosis for most fresh water, often supplied by fixed displacement axial piston pumps for new and retrofit installations. One Danfoss unit recently attained 23,000 hours of use – 15,000 more than its guarantee and is still in excellent shape. World Pumps talks to James Graham and Gary Ford.

Conference review: European Desalination Society Conference Conference review: European Desalination Society Conference

In May 2009 the spa town of Baden Baden, Germany, played host to the European Desalination Society’s Conference and Exhibition on Desalination for the Environment - Clean Water and Energy. Discussions focussed on the problems that many countries face in providing water for their populations, industries and agriculture. Bryan Orchard reports.

Materials technology for seawater pumps

Corrosion is the greatest problem encountered in stainless steel structures widely used in seawater pumps - even specialised brine pumps such as those used in desalination, oil & gas, chemical, thermal and nuclear power plants. Here, M Miyasaka and H Yakuwa of Ebara discuss the solutions currently on offer for surmounting crevice corrosion and take a look at the latest advances in this field.

Ebara seawater pumps for multi-stage flash evaporation Ebara seawater pumps for multi-stage flash evaporation

Throughout the Middle East and Arabian Gulf, multi-stage flash evaporation desalination is very much the preferred technology for the production of potable water. Several factors contribute to this, the key ones being the abundance of waste heat and the corrosive nature of the region's seawater. Bryan Orchard looks at how one company, Japan's Ebara, has addressed the issue of seawater intake pumping.

High-pressure solution for reverse osmosis applications High-pressure solution for reverse osmosis applications

Modern reverse osmosis desalination plants operate with high base load capacity and therefore the mechanical reliability and efficiency of high-pressure membrane feed pumps deserve thorough consideration. Production losses due to mechanical failure or higher energy consumption due to lower hydraulic efficiency can be significant factors in the plant operating costs. Miguel Angel Rivas, product portfolio manager for Sulzer Pumps, discusses the options available.
