COR MHI

Design Pressure boosting system with 2 to 4 parallelswitched, non-self-priming stainless steel highpressure multistage centrifugal pumps with speedcontrolled motors
Type key
Example: Wilo-COR-3 MHIE 406/VR i COR Compact pressure boosting system with integrated speed control 3 Number of pumps MHIE Pump series 4 Rated volume flow of the single pump (m³/h) 06 Number of single-pump stages VR Control unit; VR = Vario controller
Special features/product advantages
→ Compact system with outstanding price/per formance ratio due to MHIE series stainless steel high-pressure multistage centrifugal pumps with integrated air-cooled frequency converters → Super proportionally large control range → Integrated full motor protection with thermistor sensor (PTC) → Integrated dry-running detection with automatic deactivation in the event of low water via the motor control electronics
Application
→ For fully automatic water supply and pressure boosting in residential, commercial and public buildings, hotels, hospitals, department stores and for industrial systems → Pumping of drinking water and 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.
Equipment/function
→ 2-4 pumps per system → Infinitely variable control mode through the use of pumps with integrated frequency converters → Components that come in contact with fluid are corrosion-resistant → Galvanized base frame with height-adjustable vibration damper for insulation against structure-borne noise → Shut-off valve at each pump, on the suction and pressure sides → Non-return valve, pressure side → Diaphragm pressure vessel 8L, PN16, pressure side → Pressure sensor, on the discharge side → Optional pressure gauge (suction side) → Pressure gauge (discharge side) → Optional low-water cut-out switchgear
