Compact pressure-boosting system, for direct or indirect connection. Consisting of a non-self-priming, vertical stainless steel high-pressure multistage centrifugal pump in glanded version. 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, 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, firefighting water (apart from fire-fighting 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 benefits

WRAS/ACS approval of the pump for all parts that come in contact with the fluid (EPDM version)
High-efficiency pump hydraulics of the Helix V series in connection with IE3 standard motor, including 0.75 kW and larger (optional for smaller motor power)
Bidirectional mechanical seals in the pumps for easy maintenance
Flexible lantern design permits 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
Components that come in contact with the fluid are corrosion-resistant
Easy commissioning and operation with the Easy Controller
Factory testing and presetting to optimum working range
