Pumps for Abu Dhabi

Posted: Monday 22nd March 2010

On 1 December 2009, KSB Aktiengesellschaft, Frankenthal, Germany, 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. With the new pump sets, the local water utility provider complements the pump station in order to extend the supply system already in place. At this station, ten pumps of the same type series are in operation which KSB delivered in 2003.

Each of the RDLO 600-1200 B pumps weighing around 20 tonnes will handle 5,746 cubic metres of water per hour at a head of 190 metres. To ensure optimum corrosion protection, the casings, impellers and shafts are made of duplex stainless steel. The pump setsí hydraulic efficiency will be at least 87 percent.

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.

The German pump manufacturer was awarded the contract because the customer is completely satisfied with the other KSB pumps in use at the station and because KSB was able to guarantee very high levels of efficiency. Delivery is scheduled for the beginning of 2011.
