Type key

 

Example IL 40/160-4/2
IL In-line pump
40 Nominal diameter DN of the pipe connection
160 Nominal impeller diameter
4 Nominal motor power P2 in kW
2 Number of poles

 

Special features/product benefits

  • High-efficiency motors as standard; from 0.75 kW nominal motor power: motors with IE2 technology
  • Reduced life cycle costs due to optimised efficiency
  • Standard condensate drainage holes in the motor housings
  • Can be used flexibly in air-conditioning and cooling systems, with application benefits due direct draining of condensate via optimised lantern design (patented)
  • High corrosion protection thanks to cataphoretic coating
  • Bidirectional mechanical seal with forced flushing
  • High worldwide availability of standard motors (according to Wilo specifications) and standard mechanical seals
  • Easy to install due to feet with threaded holes on pump housing
