  • General
    The series of intelligent pressure boosting system BWS-HY is
    developed based on PDI control technology, to control the pump
    pressure within a certain range according to the water consumption
    with features of complete functions, reliable quality, stable operation
    and easy maintenance.
  • About BWS
    BWS, the abbreviation of Building Water System or Best Water
    System, implies the LEO’s ambition to build up the image of best
    quality product range for water supply system in the market.
    BWS series includes WG Non-negative Water Supply System, wX
    Water Non-negative Supply System, HY Constant Water Supply
    System and ZY Boosting Water Supply System. Together with WQ
    sewage pumps, XBD firefighting pumps, LPP in-line pumps and LEN
    end suction pumps, we have full range to satisfy the applications of
    secondary water supply, drainage, fire-fighting and HVAC.
  • Product Composition
    The complete device is composed from a pump unit, a pressure tank,
    a pressure sensor, PDI and accessories. If necessary, auxiliary pumps
    or pressure tanks can be added in the device.

    • Application
      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.
      Ultra-filtration systems，reverse-osmosis systems，distillation
      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.

    • Pump
      Flow: up to 760 m3/h
      Head: up to 85 m
      Power range: 0.37 -132 kW
      Liquid temperature:0°C-+90°C
      Max ambient temperature：+ 40°C
      Max operation pressure: 16 bar
      Altitude: up to 1000 m
    • Motor
      Closed construction
      Insulation class：F
      Protection class: IP 55
      IE 2 motor as standard.IE 3 motor is available on request
    • Flange
      EN 1092 and DIN 2576 standard
    • Ambient Temperature
      Max. Ambient temperature:+40°C.Ambient temperature above40°C,or
      installation at altitude of more than 1000 m 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.
      For example, when the pump is installed at altitude of more than 3500 m
      above sea level，P2 will be decrease to 88%.when the ambient
      temperature is 70°C，P2 will be decreased to 78%.
