Economy CO/T-1 Helix V 610/EC

Compact pressure-boosting system, with break tank for system separation (drinking water / drinking water or drinking water / non-drinking water) in accordance with DIN 1988 and DIN EN 1717 (fluid category 5) for indirect connection. Consisting of break tank, float valve, float switch as dry-running protection signal transmitter and a non-self-priming, vertical stainless steel high-pressure multistage centrifugal pump in glanded version. Ready for connection with pipework mounted on PE baseplate, including control unit with all necessary measuring and control devices.

For drinking water separation as well as 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-extinguishing 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.

Special features/product benefits

• Drinking water approval of the pump for all parts that come in contact with the fluid (EPDM version)
• Highly efficient pump hydraulics of the Helix V series in conjunction with IEC standard motors
• Integrated low-water detection with automatic deactivation via dry-running protection relay
• Bidirectional mechanical seal for pumps
• Flexible lantern design permits direct access to the mechanical seal
• Parts that come in contact with the fluid are corrosion-resistant
• Break tank made of polyethylene (PE) with service overflow (HT) and overflow slot according to DIN EN 13077 (can be optionally extended with an

overflow box including dirt guard)

• Calmed inlet valve, mounted in a twist-proof manner at the factory
• Pressure-loss optimised hydraulics of the entire system
