Technical data
Tender text

Compact pressure-boosting system in accordance with DIN 1988 and DIN EN 806, for direct or indirect connection. Consisting of non self-priming, switched in parallel, vertically-mounted stainless steel high-pressure multistage centrifugal pumps in glanded versions. 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 public buildings, hotels, hospitals, department stores and for 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

  • Heavy-duty system which satisfies all the requirements of DIN 1988 (EN 806)
  • WRAS/ KTW/ ACS approval of the pumps for all parts that come in contact with the fluid (EPDM version)
  • High-efficiency pump hydraulics of the Helix V series in conjunction with IE3 IEC standard motors
  • 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
  • Parts that come in contact with the fluid are corrosion-resistant
  • 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 pumps of the Helix V series
  • Base frame made of electrolytically galvanised steel, with height-adjustable vibration absorbers for insulation against structure-borne noise
  • Shut-off device on the suction and pressure sides of each pump
  • Non-return valve on the pressure side of each pump
  • Pressure sensor (4 – 20 mA), 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 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 pumps 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)

Optional accessories (factory installation or retrofitting after technical checks)

  • Manual-0-Automatic switch Preselection of the operating mode of each pump and manual operation in the event of a controller fault "Manual" (emergency/test mode available at mains power, motor protection available), "O" (pump switched off – cannot be switched on using the controller) and "Auto" (pump enabled for automatic mode via the controller)
  • Evaluation relay for PTC motor protection
  • Individual operation and fault signal, low-water signal
  • Signal converter for 0/2 –10 V to 0/4 – 20 mA
  • Soft starter for peak-load pumps
  • Connection to BMS in accordance with VDI 3814
