Efficient pumping, mixing and agitating for wastewater and water treatment

At IFAT 2022, Nord Drivesystems will be presenting intelligent drive technology for water, wastewater, waste and raw materials management. Among other things, the spotlight will be on the patented wash-down-capable DuoDrive geared motor and the SAFOMI-IEC adapter for optimised use of MAXXDRIVE industrial gear units in mixing and agitation processes.

Pump systems, as well as mixers and agitators, are elemental components in process and wastewater and engineering systems, and ensure the smooth operation of sewage treatment plants, waterworks systems and production plants. They often have to circulate large volumes of liquid or highly viscous substances, so availability, reliability and a long service life are the top priorities.

As a system supplier, Nord offers fully matched drive systems consisting of gear unit, motor and frequency inverter that are tailored to the respective requirements of the customer application. Nord drive solutions can be networked, operate autonomously, and their functions and performance are scalable.

The patented DuoDrive geared motor in robust and hygienic wash-down design integrates a high-efficiency IE5+ synchronous motor into a single-stage helical gear unit. This not only guarantees a compact size and minimal noise emissions but also high power density and overall high system efficiency. As a system, the very compact DuoDrive concept achieves energy efficiency of up to 92%, and achieves very high efficiency in the partial load range.

Together with its simple plug-and-play commissioning, the complete DuoDrive solution results in a significant reduction in Total Cost of Ownership (TCO) compared to other drive systems.

Nord will also show the SAFOMI-IEC adapter which it developed specifically for agitators. If it is used for an agitator drive instead of a standard IEC adapter, a higher operational reliability and less maintenance will be achieved. However, its main advantage is an integrated oil expansion volume, which means that oil tanks and hoses as well as the radial shaft seal, which is subject to leakage and wear between gear unit and IEC cylinder, are not required.

SAFOMI is available for MAXXDRIVE parallel gear units in sizes 7 to 11 and covers maximum output torques from 25 to 75 kNm. Nord says the compact combination of a MAXXDRIVE industrial gear unit, the SAFOMI-IEC adapter and a drive motor is a good choice for mixer and agitator applications to reduce wearing parts and attached components.

Experts from Nord Drivesystems will give their advice on these and further drive solutions for the industry at the IFAT in Munich on stand 314 in hall A1.
