CronoLine-IL is a glanded pump in in-line design with a flange connection.

It is used for pumping heating water (in accordance with VDI 2035), water-glycol mixtures and cooling and cold water without abrasive substances in heating, cold water and cooling water systems.

This single-stage, low-pressure centrifugal pump features:

  • Mechanical seal
  • Flange connection with pressure measuring connection R 1/8
  • Lantern
  • Coupling
  • IEC standard motor

Key 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

Technical data

  • Permissible temperature range -20 °C to +140 °C
  • Mains connection 3~400 V, 50 Hz (others on request)
  • Protection class IP 55
