Wilo-COR Helix VE2.0…/ECe

Highly efficient water-supply unit ready for connection with 2 to 3 vertically arranged, non-self-priming, stainless-steel high-pressure multistage centrifugal pumps from the Helix2.0-VE series, connected in parallel; each pump is equipped with an integrated air-cooled frequency converter. The system is equipped with an Easy Control ECe switchgear.

Fully automatic water distribution and pressure boosting, 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, trade and industrial companies, water supply companies).

Approved fluids are generally waters which do not attack the materials used, neither chemically nor mechanically, and do not contain any abrasive or long-fibre constituents. For example:

• Drinking water (drinking water approval in Check Material section)
• Cooling water
• Process water

2-3 pumps per system from the Helix2.0-V 6 to Helix VE 10 series, with IE5-equivalent standard motor, speed-controlled via integrated frequency converter on each pump.

ECe switchgear ensures automatic control of the complete pressure-boosting system.

Completely mounted on galvanised steel, height-adjustable base frame

Base frame: Galvanised steel, with height-adjustable vibration absorbers for comprehensive insulation against structure-borne noise as well as integrated lifting points and cable guides.

Pipework: Entire pipework made of stainless steel; suitable for the connection of conventional pipe materials. The pipework is designed pursuant to the overall hydraulic performance of the pressure-boosting system.

Pumps: 2 to 3 pumps from the Helix2.0-VE 6 up to Helix VE 10 series connected in parallel are used. The air-cooled frequency converters mounted on the pump motor enable continuous control between 25 Hz and a maximum of 60 Hz for all pumps from this series.

• For pumps Helix2.0-VE 6, 10: All pump parts in contact with the fluid are made of stainless steel with KTW/WRAS/ACS approval.

Valves: Each pump is fitted on the suction and discharge side with a standard shut-off unit with DVGW approval mark and on the discharge side with a DVGW/KTW-approved non-return valve.

Diaphragm pressure tank: 8 l/PN 16 arranged on the discharge side with a diaphragm made of butyl rubber, with DVGW/KTW approval, completely safe in accordance with food safety laws; for testing and inspection purposes, with a ball valve with drain and flow-through fixture with DVGW/KTW approval in accordance with DIN 4807.

Pressure monitoring: 2 pressure sensors: 4 to 20 mA, arranged on the discharge side and on the suction side.

Pressure indication: Pressure gauges arranged on the suction and end pressure side.

Switchgear: Easy Control ECe standard-equipped with LCD display.
