Technical data
Tender text

Compact pressure-boosting system with break tank for system separation in accordance with DIN 1988 and DIN EN 1717 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 a PE base frame, including control device with all of the 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, 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.

Special features/product benefits

  • WRAS/KTW/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 conjunction with IEC standard motors
  • Integrated dry-running detection with automatic deactivation in the event of low water via a dry-running protection relay
  • Bidirectional mechanical seals in the pumps for easy maintenance
  • Flexible lantern design permits direct access to the mechanical seal
  • Parts that come in contact with the fluid are corrosion-resistant
  • Hydraulics of entire system are pressure-loss optimised
  • Fully electronic Economy controller (CE+) with microprocessor and LEDs to indicate the system status, analogue and digital inputs and outputs
  • Factory inspection and default setting at optimum operating range (incl. inspection certificate in accordance with EN 10204 - 3.1)


  • Stainless steel high-pressure multistage centrifugal pump of the Helix V series
  • Base frame made of polyethylene (PE)
  • Shut-off device on the pressure side
  • Non-return valve on the pressure side
  • 8 litre diaphragm pressure vessel, PN 16 including throughflow fitting in accordance with DIN 4807, pressure side
  • Pressure switch (6/10/16 bar), pressure side
  • Pressure gauge, pressure side
  • Automatic pump control by means of a fully electronic

Economy controller (CE+) in a light grey polycarbonate enclosure (direct start) or sheet metal enclosure painted RAL 7035 (star-delta starting), protection class IP54, consisting of internal control voltage supply unit, microprocessor, analogue and digital inputs and outputs

Operation/ display

  • Fully electronic Economy controller (CE+) consisting of an internal power supply unit, with microprocessor and LEDs to indicate the system status, analogue and digital inputs and outputs
  • Configuration of operating parameters via potentiometer
  • Configuration of pump operating mode and acknowledgement of fault signals via H-0-A switch
  • LED display (3x7 segments, alphanumeric) to indicate the set pressure, controller parameters and error messages
  • LEDs for display of the system status (mains voltage/operation/fault/low water)
  • Lockable main switch


  • Fully automatic control for a fixed speed pumps by means of setpoint/actual value comparison
  • 4 – 20 mA sensor signal (with conductivity test) for control variable actual value
  • Operating mode of the pump freely selectable (manual, off, automatic)
  • Automatic pump test run (pump kick):
    • Can be activated by means of DIP switch
    • Time between two pump test runs is six hours
  • Zero-flow cut-off over pressure and time
  • H-0-A (manual-zero-automatic) switch: Preselection of the operating mode of the pump and manual operation in the event of a controller fault Manual (emergency/test mode available at mains power, motor protection available, automatic resetting), 0 (pump switched off – cannot be switched on via the controller) and Auto (pump enabled for automatic mode via the controller)


  • Conductivity test of the sensor cable
  • Phase failure monitoring
  • Motor current monitoring via converter in devices for direct start
  • Protection of the pump mains power feeds in devices for direct starting is provided via circuit breakers; in devices for star-delta starting it is provided via safety fuses and a contactor/motor protection relay combination
  • Monitoring of maximum and minimum system values with adjustable time delays and limits
  • Protection against low water level via contact e.g. for float switch or pressure switch
  • Input for thermal winding contact (WSK) or fault message contact (SSM) of the pump in systems for star-delta starting
  • Pipe burst monitoring


  • Potential-free contact for collective fault signal (SSM)
  • External on/off via contact for deactivation of the system automatic mode (function can be activated via DIP switch)

Recommended accessories (to be ordered separately)

  • Flexible connection pipes or compensators
  • Diaphragm expansion tank
