Tender text

High-efficiency connection-ready water-supply unit (non-self-priming) with one vertically arranged stainless steel high-pressure multi-stage centrifugal pump in glanded version of the Helix VE series.

For fully automatic water supply in inlet mode from the public water supply network or from a reservoir.

For pumping drinking water, 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.

Special features/product advantages

  • Heavy-duty system with Helix VE series stainless-steel high-pressure multistage centrifugal pumps and air-cooled integrated frequency converter
  • High-efficiency pump hydraulics in conjunction with IE4-equivalent standard motors
  • Superproportionally large frequency converter control range from 25 Hz up to a maximum of 60 Hz (version dependent)
  • Integrated full motor protection via PTC
  • Integrated dry-running detection with automatic cut-out in event of low water via performance characteristics of the motor control electronics
  • Customized systems on request

Equipment/function

  • One pump of the Helix VE series with IE4-equivalent standard motor and infinitely variable auto control with integrated frequency converter
  • Base frame made of galvanised steel, with height-adjustable vibration absorbers for insulation against structure-borne noise
  • Parts that come in contact with the fluid are corrosion-resistant
  • Stainless steel 1.4301
  • Shutting gate, pressure side
  • Non-return valve, pressure side
  • Diaphragm pressure vessel 8 l, PN16, pressure side
  • Pressure gauge, pressure side
  • Optional low-water cut-out switchgear and pressure gauge, suction side

Wired and ready for connection and piped with shut-off valve on the pressure side mounted to the base frame.
