Capacity and efficiency improved
At the beginning of 2010, KSB received the order to equip La Caldera pumping station in Mexico City with 24 large wastewater pumps. Each of the submersible motor pumps type Amarex KRT K 700-900 weighs around 10,500 kg and has an output of approximately 2000 L/s.
The pumps will be driven by 10-pole high-voltage motors of 4160 V and a drive rating of 680 kW. The impellers of the pumps measure around 800 mm in diameter. Thanks to their channel impellers, it is claimed that the pumps achieve efficiency upwards of 83%.
The station at La Caldera is a combined wastewater/stormwater pumping station with a total capacity of 40 m3/s. As the amount of stormwater to be handled has steadily increased in the recent past, the municipal authorities of Mexico City have started modernising various canals and pumping stations.
