      Suitable for transferring liquids of low viscosity, non-
      inflammable and non-explosive, not containing solid
      particles or fibers.
      Water supply&drainage for high-rise buildings,
      filtration and transfer at waterworks, pressure boosting
      in main pipe.
      Washing and cleaning systems, boiler feeding, cooling
      water circulation, water treatment systems, auxiliary
      system, support equipment.

      systems, separators, swimming pools.
      Agricultural irrigation: sprinkler irrigation, drip-feed irrigation.
      Food&beverage industry.
      Fire-fighting system.
    • Operating Conditions
      Low viscosity, non-inflammable and non-explosive liquids
      not containing solid particles or fibers. The liquids must not
      chemically attack the pump materials. When pumping liquids
      with a density or viscosity is higher than that of water, a motor
      with a higher output power rating shall be used.
      Liquid temperature：-20℃〜+ 120℃
      Flow ranges: 0.7-240 m3/h
      Liquid pH value：4-10
      Max.ambient temperature：+ 40℃
      Max. operation pressure: 33 bar
      Altitude: up to 1000 m
    • Motor
      IE 2 motor (IE 3 motor optional)
      Totally enclosed&fan-cooled
      Protection class：IP55
      Standard voltage ：50Hz 1×220V / 3×380V
    • Ambient Temperature
      Max.ambient temperature：+ 40℃.Ambient temperature
      above 40℃or installation at altitude of more than 1000 meters
      above sea level require the use of an oversize motor. Because
      of low air density and poor cooling effects, the motor output
      power P2 will be decreased. See the picture.
      In such cases, it may be necessary to use a motor with a higher
      output power rating.
