Wilo-Economy CO-Helix V…/CE

Series description

Special features/product advantages

  • Heavy-duty system which satisfies all the requirements of DIN 1988 (EN 806)
  • WRAS/ KTW/ ACS approval of the pumps for all parts that come in contact with the fluid (EPDM version)
  • High-efficiency pump hydraulics of the Helix V series in conjunction with IE3 IEC standard motors
  • The spacer coupling enables the mechanical seal to be replaced without dismantling the motor (from 7.5 kW)
  • Parts that come in contact with the fluid are corrosion-resistant
  • Easily adjustable and operationally reliable due to the CE control device used
  • Factory inspection and default setting at optimum operating range (incl. inspection certificate in accordance with EN 10204-3.1)

Design type

Pressure-boosting system with 2 to 4 parallel-switched, non self-priming, vertical high-pressure multistage centrifugal pumps made of stainless steel. Ready for connection with stainless steel pipework, mounted on a base frame, including control device with all necessary measurement and adjustment equipment.

Application

  • Fully automatic water supply and pressure boosting in inlet mode, either from the public water supply network or from a tank, for domestic, commercial, industrial and municipal applications (e.g. residential, office, administration buildings, hotels, hospitals, trades, industry, water supply companies).
  • Pumping of drinking water and process water, cooling water, fire water (apart from fire-extinguishing systems in accordance with DIN 14462 and with the approval of the local fire safety authorities) or other types of industrial water that do not attack the materials either chemically or mechanically and do not contain abrasive or long-fibre constituents.

Equipment/function

  • 2-4 pumps per system of the Helix V 4 to Helix V 52 series with IE3 standard motor
  • Automatic pump control by means of Economy CE control
  • Parts that come in contact with the fluid are corrosion-resistant
  • Zinc-coated steel base frame with height-adjustable vibration absorber for insulation against structure-borne noise
  • Pipework made of 1.4301 stainless steel
  • Shut-off device on the suction and pressure sides of each pump
  • Non-return valve on the pressure side of each pump
  • Pressure sensor, on the discharge side
  • Optional pressure gauge (suction side)
  • Pressure gauge (discharge side)
  • Optional low-water cut-out switchgear

Scope of delivery

  • Factory-mounted, ready-for-connection pressure-boosting system checked for functionality and impermeability
  • Packaging
  • Installation and operating instructions
