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.

NORD DRIVESYSTEMS integrated pump drives can store up to four operation modes that can be displayed and changed directly at the control unit

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.

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 – in stand-alone and mobile applications as well as in complex setups 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 – increasing efficiency 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.

About us :

NORD DRIVESYSTEMS develops, produces and sells drive technologies with around 3.000 employees, and is one of the international leaders in the industry. In addition to standard drives, NORD supplies application-specific concepts and solutions, even for special applications, for example with energy-saving drives or explosion-protected systems. Gross sales amounted to approx. EUR 450 mn in the 2012 business year. The company founded in 1965 now has over 35 subsidiaries worldwide. The closely meshed sales and service network ensures optimum availability for short delivery times and customer-oriented services. NORD produces a wide variety of drive units for torques from 10 to 200,000 Nm, electric motors with powers from 0.12 kW to 200 kW as well as the necessary power electronics in the form of frequency inverters and servo controllers. Inverter solutions are available for classical installations in the switch cabinet and for decentralised and fully integrated drive units.
