Series description


Highly efficient water-supply unit ready for connection with one vertically arranged non-self-priming high-pressure multistage centrifugal pump of the Helix VE series with integrated air-cooled frequency inverters.


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 (a standby pump to be provided to comply with DIN 1988 and DIN EN 806).

Approved fluids are generally waters which do not attack the materials used, neither chemically nor mechanically, and do not contain any abrasive or long-fiber constituents like:

  • Drinking water (check drinking water approvals in materials section)
  • Cooling water
  • Process water
  • Firefighting water (apart from fire-extinguishing systems in accordance with DIN 14462 and with the approval of the local fire safety authorities)


1 pump of the Helix VE 2 to Helix VE 52 series, with IE4-equivalent standard motor speed controlled via integrated frequency inverter mounted on galvanized steel height adjustable base frame.

All components in contact with fluid are corrosion resistant.

On pressure side:

  • Shut-off valve
  • Non return valve
  • Check-valve
  • Diaphragm pressure vessel 8 l, PN 16
  • Pressure sensor 4..20mA
  • Pressure gauge
  • On suction side
  • Pressure sensor 4..20mA
  • Pressure gauge

Scope of delivery
