SIBOOST PC 2 HELIX2.0 VE 404-EM

Compact Multi Pump pressure-boosting system in accordance with DIN 1988 and DIN EN 806, for direct or indirect connection to Main Supply. Consisting of non-self-priming, switched in parallel, vertical stainless steel high-pressure multistage centrifugal pumps. Ready for connection with stainless steel pipework, mounted on a base frame, including integrated control by the frequency converter with all necessary measuring and control devices.

For fully automatic water supply and pressure boosting in residential, commercial and public buildings, hotels, hospitals, department stores and for industrial systems.

For pumping drinking water, process water, cooling water or other service water, which does not affect the materials used, neither chemically nor mechanically, and does not contain any abrasive or long-fibre constituents.

Special features/product benefits

• Heavy-duty system that fulfils all the requirements of DIN 1988 (EN 806)
• REG4 (KIWA/WRAS/KTW/ACS) approval of the pumps for all parts that encounter the fluid (EPDM version)
• Helix2.0 VE series high-efficiency pump hydraulics, combined with IE5 EC motor drives, with air-cooled integral frequency converters
• Pressure-variable (pv) control mode ensures optimum pump load adjustment and parallel synchronous speed control increases energy savings
• Disproportionately large frequency converter control range of 25 Hz up to a maximum of 60 Hz saves energy
• Integrated dry-running detection with automatic cut-out in event of low water via performance characteristics of the motor control electronics
• Bidirectional mechanical seals in the pumps for easy maintenance
• The flexible lantern design enables direct access to the mechanical seal
• Hydraulics of entire system are pressure-loss optimised
• Parts that encounter the fluid are corrosion-resistant
• Ready for integration into building automation via standard-equipped Modbus TCP and BACnet IP (native), Modbus RTU and BACnet MS/TP via adapter from USB to RS485
• Factory testing and presetting to optimum working range

Equipment/function

• Helix2.0 VE2 to Helix2.0 VE16 series stainless steel high-pressure multistage centrifugal pump
