Optimal pump load regulation thanks to variable pressure control (pv) and parallel synchronous speed control for additional energy savings
Noise levels up to 20 dB(A) lower than in conventional systems at comparable hydraulic output
Very wide frequency converter control range: 20 Hz to a maximum of 50 Hz
Maintenance-free pump type without mechanical seals
High reliability due to various safety functions including overload protection, dry run protection and automatic shutdown
SCe control unit makes the system easy to set up and operate, thanks to LCD display and green adjusting button
Potable water tolerance for all components in contact with pumped media
Ready for integration into building automation system with SCe control unit via Modbus RTU serial protocol

Type

Low-noise, ready for connection water-supply unit with 2 to 4 vertically arranged vertically arranged normal-suction stainless steel high-pressure multistage centrifugal pumps of the MVISE range in glanded version. Each pump is equipped with a built-in water-cooled frequency converter. The system is equipped with the Smart Controller SCe.

Application

• Fully automatic water supply and pressure boosting with pumped water either from the public water mains or from a reservoir at min. 0.5 m above the pump for private, industrial and municipal applications (e.g. domestic, commercial and office buildings, hotels, hospitals, industrial facilities, water supply companies). According to DIN 1988 and DIN EN 806 a back-up pump is included.
• Approved pumped liquids are generally waters, which do not have aggressive chemical and mechanical effects on the materials used and do not contain abrasive and long-fibre constituents, such as
  • Drinking water
  • Cooling water
  • Processing water
  • Extinguishing water (apart from water for fire extinguishing systems as per DIN 14462; with the approval of the local fire authority).

Equipment/function

• 2 to 4 pumps of the MVISE range per installation with wet rotor motor and 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
