Description
Compact pressure-boosting system according to DIN 1988 and DIN EN 806, for direct or indirect connection. Consisting of non-self-priming, parallel-connected, vertically mounted, stainless steel high-pressure multistage centrifugal pumps in glanded versions, for which each pump is fitted with a frequency converter. Ready for connection with stainless steel pipework, mounted on a base frame, including control device with all necessary measurement and adjustment equipment.
For fully automatic water supply and pressure boosting in residential, commercial and administrative buildings, hotels, hospitals, department stores and for industrial systems.
For pumping drinking water, process water, cooling water, firefighting water (apart from fire-fighting systems in accordance with DIN 14462 and with the approval of the local fire protection 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.
- Heavy-duty system that fulfils all the requirements of DIN 1988 (EN 806)
- WRAS/KTW/ACS approval of the pumps for all parts that come into contact with the fluid (EPDM version)
- Helix VE series high-efficiency pump hydraulics, combined with IE5 IEC standard motors, with air-cooled integral frequency converters
- Pressure-variable (pv) control mode ensures optimum pump load adjustment and parallel synchronous speed control increases energy savings
- Energy-saving thanks to superproportionally large frequency converter control range of 25 Hz up to a maximum of 60 Hz
- 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
- The spacer coupling enables the mechanical seal to be replaced without dismantling the motor (from 7.5 kW)
- Hydraulics of entire system are pressure-loss optimised.
