Record efficiency during test run

At the beginning of March 2007, three high-pressure pumps destined for use in the Dhekelia seawater desalination plant in Cyprus passed their performance tests on KSB´s Frankenthal test stand with flying colours.

Witnessed by representatives of the Spanish plant engineering contractor and the Cypriote plant operator, an inspector from "Lloyd's Register Inspection Ltd." certified one of the best efficiencies ever reached by a multistage high-pressure pump with cold water.

Each of the three HGM-RO 8/3 achieved an efficiency of 87 per cent pumping water of 20 °C. At its best efficiency point, this radially split ring-section pump type handles 1100 m³/h at a discharge head of 615 metres and a pump input power of around 2.1 MW.

The tested units are part of a supply package totalling 25 pumps from different series which will help the operating company reduce the operation costs of the seventeen-year-old desalination plant. Compared with their predecessors, KSB´s high-pressure pumps feature better efficiency and markedly lower energy consumption.

The desalinated water produced in the plant will be pumped to a national water reservoir close-by. As the Spanish engineering contractor has a prominent international profile and has successfully built seawater desalination plants all over the world, this first order placed with the German pump manufacturer represents a significant reference contract.
