High energy efficiency thanks to IE4 motor and optimized hydraulics
Very wide frequency converter control range (25 Hz to max. 60 Hz) extends the range of applications
High reliability through a variety of protection functions, including overload protection, dry run protection and automatic shutdown.
With the SCe control unit, the system is easy to set up and easy to operate thanks to the LCD display and the green adjusting button.
Ready for integration into building automation system with SCe control unit via Modbus protocol

Type

Pressure booster system with 2 to 4 vertically arranged normally aspirated MVIE 70 or 95 series centrifugal pumps, connected in parallel. Each pump is equipped with a built-in air-cooled frequency converter. The system is equipped with the Smart Controller SCe.

Application

• Fully-automated water supply and pressure boosting system for domestic, industrial and civil applications (e.g. accommodation, office and administration buildings, hotels, hospitals, industrial facilities, water supply companies). According to DIN 1988 and DIN EN 806 a back-up pump is included.
• Permitted to be pumped is generally water that does not have aggressive chemical and mechanical effects on the materials used and does not contain abrasive and long-fibre constituents, such as
  • Drinking water (depending on drinking water tolerances, see Materials section)
  • Clean water
  • Cooling water
  • Process water
  • Extinguishing water (except water for fire extinguishing systems according to DIN 14462; with the approval of the local fire department)

Equipment/function

• 2 to 4 pumps per unit Helix MVIE series (70 or 95), with speed control via integrated frequency converter on each pump.
• The SCe control unit provides automatic regulation and control of the pressure boosting unit.
• Fully assembled on a height adjustable galvanized steel base frame.
• All parts in contact with the pumped liquid are corrosion resistant.
• On the pressure side:
  • Shut-off valves.
  • Non return valve
  • Non return valve at each pump
  • Expansion vessel 8 l diaphragm tank, PN 16
  • Pressure sensor 4...20 mA
  • Pressure gauge
• On suction side
  • Shut-off valve
  • Pressure sensor 4...20 mA
  • Pressure gauge
