Wilo-SiBoost Smart Helix EXCEL

Series description

Special features/product advantages

  • Heavy-duty system featuring stainless steel high-pressure multistage centrifugal pump from the Helix EXCEL series with integrated frequency converter from 25 Hz to a maximum of 60 Hz
  • High-efficiency EC motor (energy efficiency class IE5 in accordance with IEC 60034-30-2)
  • Pressure-loss optimised overall system with highly efficient pump hydraulics
  • Optimum load adjustment of the system to the overall system through the extra control mode Δp-v
  • Improved monitoring and leakage detection via optional interface with SCADA connection
  • Maximum degree of control thanks to use of an SCe control device with LCD display, simple navigation and adjustment using rotary knob
  • Integrated dry-running detection with automatic deactivation via the motor control electronics


In densely populated rural areas, the transportation of water is often associated with leakage risks. This results in high operating costs. Our solution: the Wilo-SiBoostSmart Helix EXCEL significantly reduces overall power consumption thanks to its top-quality components (hydraulics and motors) as well as a switchgear which supports leakage detection via an optional communication interface.

Design type

Highly efficient water-supply unit (non self-priming) ready for connection with 2 to 4 vertically arranged Helix EXCEL stainless steel high-pressure centrifugal pumps switched in parallel; each pump is equipped with an integrated air-cooled, high-efficiency frequency converter and an EC motor, including Smart Controller SCe. Valves and sensors are protected for safe and reliable installation


  • 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.


  • 2 – 4 pumps per system of the Helix EXCEL 4 to Helix EXCEL 52 series, with high-efficiency EC motor and continuous speed control via integrated frequency converter on each pump
  • Automatic pump control via Smart Controller SCe
  • Parts that come in contact with the fluid are corrosion-resistant
  • Base frame made of galvanised steel, with height-adjustable vibration absorbers for insulation against structure-borne noise
  • Shut-off device on the suction and pressure sides of each pump
  • Non-return valve on the pressure side of each pump
  • Diaphragm pressure vessel 8 l, PN 16, pressure side
  • Pressure sensor, pressure side
  • Pressure gauge, pressure side
  • Removable cover for protection of system components (not for Helix EXCEL 52 series)
  • Optional low-water cut-out switchgear with pressure gauge, suction side
