Water / Waste water

Drive technology for the water industry: Reliable, accurate and efficient

Drive technology is crucial when it comes to the availability and efficiency of pumping stations and compressors in the water industry.
Here, Siemens offers harmonized and coordinated drive solutions for all applications in the water / waste water / water transportation sector – from just a few Kilowatts to up to more than 70 Megawatts. They optimize the reliability and quality of the water supply and water treatment plants using precise processes and maximum availability. At the same time, they guarantee low operating costs and a high degree of cost-effectiveness.

Fit for continuous use – reliable motors form the basis for a high plant availability

Equipment used both in the untreated water pumping stations, or the large Pipeline-Booster stations, the water and waste water pumping stations, or the water or waste water treatment plants must often run for long periods of time or even continuously. Our motors increase the availability of the complete system thanks to their robust design, long service lifetime as well as low maintenance and reliable operation.

Variable-speed operation results in higher efficiency

Using a drive converter is very worthwhile, especially for pump drives that are typically used in water supply and water treatment plants, or compressors for stabilizing ponds. Variable-speed operation saves up to 50 % of energy, makes processes more flexible and therefore reduces the amount of stress on the complete plant or system. Thanks to these cost savings, the pay-back time for a frequency converter drive is often just a few months. The cost-saving potential and pay-back time of such an investment can be quickly and simply calculated using our SinaSave energy-saving program.

The matching drive converters completely utilize the cost-saving potential

Siemens drive converters, such as the SINAMICS G150 for low voltage and SINAMICS GM150 and ROBICON Perfect Harmony for medium voltage, have a concept that is designed to effectively utilize the energy-saving potential. These drive converters have been specifically designed for drive applications without regenerative feedback into the line supply – especially for turbo machines such as pumps and compressors. The newest IGBT technology makes such high efficiency possible, whereby the thermal load of the installation location and the size of the necessary climate control equipment are reduced. The correct drive converters for specific customer requirements: The Sinamics S150 for low voltage enables operation with a low circuit feedback.
