Wilo-Comfort-Vario COR MVIE.../SCe

Description de la série de fabrication

Vos avantages

  • High energy system efficiency thanks to IE4 motor and optimised hydraulics
  • Disproportionately large frequency converter control range from 25 Hz up to a maximum of 60 Hz for a large field of application
  • High reliability thanks to various protective features including overload protection, dry-running protection and automatic deactivation.
  • Easy setting and operation with the SCe control panel thanks to LCD display, and green knob for adjustment.
  • Ready for building automation integration with the SCe control panel via Modbus

Conception

Pressure boosting system ready for connection with 2 to 4 vertically arranged non-self-priming high-pressure multistage centrifugal pumps of the MVIE 70 or 95 series switched in parallel. Each pump is equipped with integrated air-cooled frequency inverters. The system features a Smart Controller SCe.

Utilisation

Fully automatic water supply and pressure boosting system in inlet mode or from a tank, for domestic, commercial, industrial and municipal applications (e.g. residential, office, administration buildings, hotels, hospitals, trades, industry or water supply companies). Standby pump included in accordance with DIN 1988 and DIN EN 806.

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

  • Drinking water (depends on required drinking water approvals, please check materials section)
  • Pure water
  • Cooling water
  • Process water
  • Firefighting water (apart from fire-extinguishing systems in accordance with DIN 14462 and with the approval of the local fire safety authorities)

Équipement/Fonction

2-4 pumps per system of the MVIE (70 or 95) series with speed controlled motor via integrated frequency inverter on each pump.

SCe control panel ensures automatic control of the complete booster set.

All is mounted on galvanized steel height adjustable base frame.

All components in contact with fluid are corrosion resistant.

Description/Construction

Base frame: galvanized and provided with height-adjustable vibration absorbers for comprehensive insulation against structure-borne noise as well as integrated lifting points.

Pipework: complete pipework made of stainless steel, suitable for the connection of all piping materials used in building services. The pipework is dimensioned according to the overall hydraulic performance of the pressure boosting system

Pumps: 2 to 4 pumps from the series MVIE 70 and MVIE95 switched in parallel are used. The air-cooled frequency inverters mounted on the pump motor enable continuous auto control between 25 Hz and a maximum of 60 Hz for all pumps of these series. All pump parts in contact with fluid are made of stainless steel/grey cast iron with cataphoretic coating with ACS approval.

Valves: each pump is fitted on the suction and pressure side with a shut-off valve with DVGW approval mark or annular shut-off valves and a pressure-side DVGW-approved non-return valve.

Diaphragm pressure vessel: 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 throughflow fitting with DVGW/KTW approval in accordance with DIN 4807

Pressure monitoring: 2 Pressure sensors: 4..20 mA, located on the pressure and suction sides.

Pressure indication: pressure gauge arranged on the suction and the discharge sides.

Control panel: Smart Controller SCe as standard with LCD display.
