Energy-efficient pump drive solutions Permanently full speed? Not such a good idea for pump drives! Speed control balanced to actual requirements greatly enhances the energy efficiency of pump systems. NORD DRIVESYSTEMS supplies complete pre-assembled distributed drive units for a wide performance range to 22 kW. In addition to energy savings of up to 60%, users benefit from reduced noise emissions, low wear, and increased plant service life as well as the ecological advantages. Illustration: NORD DRIVESYSTEMS integrated pump drives can store up to four operation modes that can be displayed and changed directly at the control unit The SK 200E series comprises reliable and economical frequency inverters especially tailored to pump applications that precisely adjust power output as required. They are compatible with mains voltages worldwide. NORD configures complete drive systems for various application areas (IP55/IP66, ATEX zone 22/3D). Integrated process and PI controller functions enable the fully automated control of process variables and compensation of disturbances ¨C in stand-alone and mobile applications as well as in complex setup with several drives. Thanks to two analog inputs, the inverters can directly process sensor data such as pressure or flow rate. Optional signal and power plug connectors facilitate handling and ensure compatibility. A programmable energy-saving function automatically reacts to partial load operation ¨C increasing efficienc and significantly reducing running costs. Operation is straightforward and flexible via control terminals, bus, or via an optional potentiometer that enables adjustments directly at the inverter. Up to four operation modes can be stored, saving setup time; for instance during cleaning cycles or media changes. The customized parameters can be quickly exported to other units via a pluggable storage module, the system bus, or Ethernet interfaces. With control cabinets no longer required, the decentralized option minimizes cabling effort for users, and since the inverter is supplied pre-assembled the electrotechnical effort during installation is minimal. Company Background A developer and manufacturer of drive technology, NORD DRIVESYSTEMS employs some 3,000 people and is one of the world's leading suppliers of full-scale, comprehensive drive solutions. NORD's portfolio ranges from standard drives to customized solutions for demanding application requirements, e.g. based on energy-efficient or explosion-protected drives. Gross sales amounted to approx. EUR 450 mn in the 2012 business year. Founded in 1965, the company has grown to include over 35 subsidiaries around the world today. NORD has established an extensive distribution and service network to ensure minimal lead times and provide customer-oriented services wherever needed on short notice. NORD's wide variety of gear types covers torques from 10 Nm to 250,000 Nm and more. The company also manufactures motors delivering outputs from .12 kW to 200 kW, and power electronics ranging from frequency inverters to servo controllers. NORD's inverter line-up features conventional models for installation in control cabinets as well as design types for fully integrated drive units in decentralized automation environments. www.nord.com Getriebebau NORD GmbH & Co.
