Electrical Information
 

Rated current and speed

  • Standard information on the motor data can be found directly with the respective product in the data sheet.


Starting currents 

  • Generally, the starting currents for IE3 motors are 9-11 x IN


IE3 

  • As of 01.01.2017, motors (≥ 0.75 kW) built and sold within the EU must comply with the new IE3 standard.
     

NEMA and other international standards

  • As of 01.07.2016, motors (≥ 1 HP) manufactured or distributed in the USA must comply with the current NEMA Premium Standard.
    The standard is documented via a CC number from the DOE.
  • We also offer solutions for other international standards. You can find these under Downloads in the Technical Information "Electrical". 
    On request, we offer solutions with standard motors.

Mechanical Information
 

Pump curves

  • Pump curves are based on water with a viscosity of 1cSt.
  • In our characteristic curve fields, the pressure is plotted against the volume flow rate.
    The conversion from bar to mFs can be done simplified with the factor 10. 1 bar corresponds to approx. 10 mFs.
  • When using higher viscosity fluids, e.g. oil, the pump curve for centrifugal pumps generally decreases.
    Please contact our Sales Department for a characteristic curve related to your specific application.

  
Weights and measures 

  • All weights and dimensions can be found in our Catalogs.

  
Direction of rotation
