NORD SK 200E pump drives

Capable of storing up to four operation modes that can be displayed and changed directly at the control unit, the SK 200E series integrated pump drives from NORD DRIVESYSTEMS are said to include reliable and economical frequency inverters, especially tailored to pump applications that require precise adjustments of power output.

NORD configures complete drive systems for various application areas (IP55/IP66, ATEX Zone 22/3 d), in powers up to 22 kW, and its integrated process and PI controller functions enable the fully automated control of process variables as well as compensation of disturbances.

Due 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 reducing running costs.

Operation is straightforward and flexible via control terminals, bus or an optional potentiometer that enables adjustments directly at the inverter.

In addition, the customised 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 decentralised option minimises cabling effort for users, and since the inverter is supplied pre-assembled the installation effort is reduced.
