Wilo-SiBoost Smart Helix VE

Series description

Your advantages

  • Sturdy system with stainless steel high-pressure multistage centrifugal pumps of the Helix VE series with integrated frequency converter
  • Over-proportionally wide control range from 25 Hz up to a maximum of 60 Hz
  • Pressure-loss optimised entire system
  • Integrated dry-run detection with automatic deactivation via the motor control electronics
  • Maximum degree of control using the SCe control device with LCD display, simple navigation and adjustment using rotary knob

Construction

Highly efficient water-supply unit ready for connection with 2 to 4 vertically arranged non-self-priming stainless steel high-pressure multistage centrifugal pumps of the Helix VE series switched in parallel, each pump is equipped with an integrated air-cooled frequency inverter. The system features a Smart Controller SCe.

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). Standby pump included in accordance 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)

Equipment/function

2-4 pumps per system of the Helix VE 2 to Helix VE 52 series, with IE4-equivalent standard motor speed controlled via integrated frequency inverter on each pump.

SCe control panel ensures automatic control of the complete booster set.

All is mounted on galvanized steel height adjustable base frame.

All components in contact with fluid are corrosion resistant.
