Pumps for Abu Dhabi

KSB Group received an order for four large water pumps in the million-euro range to be installed in the Shuweihat pump station in the Abu Dhabi emirate. At this station, 10 pumps of the same type series which KSB delivered in 2003 are in operation.

Each of the RDLO 600-1200 B pumps weighing around 20 tonnes will handle 5746 cubic metres of water per hour at a head of 190 m. To ensure optimum corrosion protection, the casings, impellers and shafts are made of duplex stainless steel. The pump sets’ hydraulic efficiency will be at least 87%.

Once complete, all four pump sets will be submitted to a so-called string test by specialists at a KSB factory. Unlike common practice with pumps of such size, the pumps will be tested using the original drive components instead of the test field motors. To this effect, the transformer and frequency inverter, as well as the motor belonging to the individual pump, are set up to be tested as one complete unit.
