KSB nets big pumps order in Mexico
4 Mar 2010
Mexico City – KSB de Mexico, SA de CV is currently working on a new order to equip La Caldera pumping station in Mexico City with 24 large waste water pumps. Some 16 of these are among the largest waste water pumps that KSB is building at its plant in Halle, Germany.
According to KSB, each of the submersible motor pumps weighs around 10,500 kg and has an output of around 2,000 litres per second. The pumps will be driven by 10-pole high-voltage motors of 4,160 V and a drive rating of 680 kW. The pump impellers, meanwhile, measure around 800 millimetres in diameter. Thanks to their channel impellers, the pumps achieve an efficiency upwards of 83%.
La Caldera is a combined waste water/stormwater pumping station with a total capacity of 40 cubic metres per second. During heavy downpours, parts of the city are flooded by stormwater and waste water, so Mexico City authorities have started modernising various canals and pumping stations – prioritising La Caldera, which is one of the worst affected parts of the city.
KSB said it won the order against “stiff” North American and Spanish competition, in part because it could have the first pump units ready for shipment already in May of this year.
