Series description

Special features/product advantages

  • Sturdy system with Helix VE stainless steel high-pressure circulation pumps with integrated frequency converter that can be controlled from 25 Hz to 60 Hz
  • High-efficiency pump hydraulics
  • Entire system is pressure-loss optimised
  • Integrated dry-running detection with automatic deactivation via the motor control electronics
  • Maximum degree of control using the CCe control device with additional functions, micro-computer control and touch display

Design type

Highly efficient water-supply unit ready for connection (non self-priming). With 2 to 6 vertically arranged Helix VE series stainless steel high-pressure centrifugal pumps in glanded version switched in parallel; every pump is equipped with an integrated air-cooled frequency converter, including Comfort Controller CCe

Application

  • Fully automatic water supply and pressure boosting in residential, commercial and public buildings, hotels, hospitals, department stores and for industrial systems.
  • 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

  • 2-6 pumps per system of the Helix VE 4 to Helix VE 16 series, with IE4-equivalent standard motors and variable auto control with integrated frequency converter for each pump
  • Automatic pump control via Comfort Controller CCe
  • 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 valve on the suction and pressure sides of each pump
  • Non-return valve on the pressure side of each pump
  • Diaphragm pressure vessel 8 l, PN16, pressure side
  • Pressure sensor, pressure side
  • Pressure gauge, pressure side
  • Optional low-water cut-out switchgear with pressure gauge, suction side
