Series description
Wilo-CO/T-1 Helix V.../EC

Design

Water-supply unit with system separation and a non-self-priming high-pressure multistage centrifugal pump

Application

  • Fully automatic water supply including break tank for indirect connection to the public water supply network
  • 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

  • 1 Helix V series pump
  • Maximum number of stages: 14
  • PE break tank, atmospherically ventilated (150 l)
  • Corrosion-resistant components in contact with the fluid
  • Shut-off valve, on the discharge side
  • Non-return valve, on suction side
  • Break tank including float valve and float switch (low-water signal transmitter)
  • Diaphragm pressure vessel 8 l, PN 16, on the discharge side
  • Low-water cut-out switchgear
  • EC-control with IP54 plastic housing, consisting of an internal power supply unit, microprocessor, analogue and digital input and output modules
