Design

Highly efficient, ready for connection water-supply unit (non self-priming) with 2 to 6 vertically arranged glanded stainless steel high-pressure multistage centrifugal pumps from the Helix V series switched in parallel, including Comfort Controller CC (available with and without frequency converter)

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).
  • 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 V 4 to Helix V 52 series with IE3 standard motor, including 0.75 kW and larger (optional for smaller motor power)
  • Automatic pump control via Comfort Controller CC. The COR systems are additionally equipped with a frequency converter in the switch cabinet.
  • 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
  • Pipework made of 1.4571 stainless steel
  • 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
  • Optional low-water cut-out switchgear with pressure gauge, suction side
