Comfort-Vario COR/T-1 Helix2.0 VE...-GE

Design

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

Application

• Fully automatic water distribution and 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 and administrative buildings, workshops, industrial and agricultural enterprises, water supply companies).
• Pumping of drinking water and process water, cooling water, fire water (apart from fire-fighting 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

• One pump of the Helix2.0-VE 4 or Helix2.0-VE 6 series with IE5-equivalent standard motor and continuous control mode with integrated frequency converter
• PE break tank, atmospherically ventilated (150 l) for direct connection to the public water supply network. System separation takes place in accordance with DIN EN 1717, "Free drain", type AB in accordance with EN 13077
• 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
