The deciding factor for the availability and efficiency of pump and blower stations in the water industry is the drive technology. Therefore a reliable long-term and continuous operation is a requirement. In other words: The absolute failure-free operation is essential, as well as the highest efficiency. Since drives that run continuously, energy costs are a very high priority.

Our portfolio for the water industry includes motors and drive converters with a power rating of a few Watts up into the high double-digit Megawatt range, low-voltage drives as well as medium-voltage drives.

MOTOX: Geared motors

Our MOTOX series of geared motors have output torques up to 20,000 Nm and higher rated gear unit torques than conventional geared motors but with the same envelope dimensions. All gear unit types are available in the power range from 0.09 kW to 200 kW – from helical through offset shaft, helical bevel and helical worm up to worm geared motors. They are best suited for applications such as longitudinal and rotary scrapers, rakes, mixers or spiral conveyers.

Micromaster, Sinamics, Perfect Harmony: Frequency Converters

Flow rates can be controlled far more precisely and faster with variable-speed drive systems than when using mechanical control concepts – and can be adapted to the actual demand. The advantage: A significantly higher degree of reliability and quality for water and wastewater systems. Further, variable-speed operation opens up enormous cost-saving potential depending on the charachteristic up to 50%, in extreme cases up to 705 this is the reason that a drive converter often has a payback time of just a few months.

With SINAMICS, Siemens is offering an innovative family of drives that sets standards in the range from 0.37 kW up to 1500 kW in every perspective. In addition to a standard and simple operator control philosophy, the members of the SINAMICS family all use the SIZER engineering tool for selecting and dimensioning as well as STARTER for commissioning and diagnostics.

The MICROMASTER family of drive converters addresses drive applications in the power range from 0.12 kW to 250 kW and distinguishes itself as a result of the extremely easy handling – from installation & mounting through commissioning up to operation.

ROBICON Perfect Harmony rounds off our drive portfolio in the medium-voltage level. It is the undisputed No. 1 worldwide in medium-voltage drive converters regarding both market share as well as installed power. With this drive unit, low-voltage cells are connected in series so that a medium-voltage drive converter is created that can be extremely precisely scaled – over a wide voltage and power range. Presently, this drive unit is considered to be the most compact medium voltage drive converter in the market.
