Compact pressure boosting system, for direct or indirect connection. Consisting of a non self-priming, vertically-mounted stainless steel high-pressure centrifugal pump in a glanded version, for which the pump is fitted with a frequency converter. Ready for connection with stainless steel pipework, mounted on a base frame, with all necessary measurement and adjustment equipment.
For fully automatic water supply and pressure boosting in residential, office and administrative buildings, hotels, hospitals, department stores (systems with a standby pump are to be provided for this purpose within the scope of DIN 1988 and DIN EN 806) as well as in industrial systems.
For pumping drinking water, process water, cooling water, fire water (apart from fire-extinguishing 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.
Special features/product advantages
•Sturdy system due to MVIE series stainless-steel high-pressure centrifugal pumps with air-cooled integrated frequency converter
•Frequency converter with superproportionally large control range
•Integrated full motor protection via PTC
•Integrated dry-running detection with automatic cut-out in event of low water via performance characteristics of the motor control electronics
Equipment/function
1 pump of the MVIE (70 or 95) series with speed controlled motor via integrated frequency inverter mounted on galvanized steel height adjustable base frame.
All components in contact with fluid are corrosion resistant
On pressure side:
•Shut-off valve
•Non return valve
•Diaphragm pressure vessel 8 l, PN 16
•Pressure sensor 4..20mA
•Pressure gauge
On suction side:
•Pressure sensor 4..20mA
