Note:

Drinking water installations according to DIN 1988, part 5 must include a standby pump.

Selection with standby pump according to duty chart:
12-pump system
23-pump system
34-pump system
4Select system with next largest pump

If a standby pump is not necessary, the duty chart number corresponds to the number of pumps needed to achieve the calculated maximum system output.

Tender text

Compact pressure boosting system according to DIN 1988 and DIN EN 806, for direct or indirect connection. Consisting of non self-priming, switched in parallel, horizontally-mounted stainless steel high-pressure 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 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 approval of the pumps for all parts that come in contact with the fluid (EPDM version)
  • Pumps of the MHIE series in conjunction with IE2 IEC standard motors, fitted with air-cooled built-in frequency converters
  • Energy-saving thanks to a super-proportionally wide control range of the frequency converter from 25 Hz up to a maximum of 60 Hz
  • Very high degree of control and extremely simple operation with red-button technology
  • Integrated dry-running detection with automatic cut-out in the event of low water (accessories - WMS kit) via performance characteristics of the motor control electronics
  • Bidirectional mechanical seals for pumps
  • Parts that come in contact with the fluid are corrosion-resistant
  • Control device VR, with advanced functions, microprocessor and LC display (backlit) for display of the operating data, including analogue and digital inputs and outputs for control and linking of speed-controlled single pumps
  • Factory inspection and default setting at optimum operating range (incl. acceptance test certificate based on EN10204 - 3.1)

Equipment/function

  • Stainless steel high-pressure centrifugal pumps of the MHIE series
  • Base frame made of electrolytically galvanised steel, with height-adjustable vibration absorbers for insulation against structure-borne noise
  • Shut-off valve on the suction and pressure sides of each pump
  • Non-return valve on the pressure side of each pump
  • 8 litre diaphragm pressure vessel, PN16 including throughflow fitting to DIN 4807, pressure side
  • Pressure sensor (4-20 mA), pressure side
  • Pressure gauge, pressure side
  • Automatic pump control by means of a fully electronic

Vario controller (VR) in a sheet metal enclosure painted RAL 7035, protection class IP 54 consisting of an internal power supply unit, microprocessor, analogue and digital input and output modules, for controlling electronic pumps with frequency converters.

Operation/ display

  • Fully electronic Vario controller (VR) with internal power supply unit, microprocessor, analogue and digital inputs and outputs for control and linking of speed-controlled single pumps
  • Factory-preset parameters for easy commissioning/start-up
  • Configuration of setpoint, operating parameters and acknowledgement of fault signals using red-button technology
  • LC display (backlit) for display of the operating data, controller parameters, operating statuses of the pumps, actual pressure, error messages and history log
  • LEDs for display of the system status (operation/fault/low water/overpressure)
  • Lockable main switch
  • Menu navigation with symbols
  • Locking the parameter settings
  • Operation selectable with / without standby pump
  • Elapsed time indicator for each pump
  • Elapsed time indicator for entire system
  • Mains on/off counter for each system
  • Fault log for the last 9 faults

Control

  • Fully automatic control for 1 to 4 frequency-controlled pumps by means of setpoint/actual value comparison
  • 4-20mA sensor signal (with conductivity test) for control variable actual value
  • Automatic, load-sensitive cut-in of 1 to n peak-load pump(s) depending on the pressure - constant, p-c control variable
  • Pressure surge-free switching off/on of base-load and peak-load pumps thanks to adaptive PID controller
  • Operating mode of the pumps freely selectable (manual, off, automatic)
  • Automatic pump cycling:
    • The base-load pump is cycled at each new demand after system shutdowns, regardless of operating hours
    • Pump cycling dependent on operating hours, cycling of the base-load pump after six operating hours
  • Automatic pump test run (pump kick), alternately: Automatic pump test run (pump kick) in standby mode
  • H-A (manual/automatic) switch: Manual (emergency/test operation in the event of controller fault, pump speed is varied by adjusting the control voltage by means of a potentiometer) and Auto (pump enabled for automatic operation via control unit)

Monitoring

  • Actual value of the system is output via a 0-10 Volt analogue signal for external measurement / display applications, 10 Volt depending on the sensor range value
  • Conductivity test of the sensor cable
  • Protection of the pump mains power feed via circuit breaker (not for version without power element)
  • Automatic changeover to the standby pump in the event of a operating pump fault
  • Monitoring of maximum and minimum system values with adjustable limits
  • Zero-flow test for deactivation of the system if no water is extracted, the base-load pump is switched off at Q = 0, with adjustable follow-up time
  • Protection against low water level via contact e.g. for float switch or pressure switch with adjustable follow-up time
  • Potential-free contacts for collective run signals (SBM) and collective fault signals (SSM), external activation/deactivation of the system via contact
  • Optional: Individual operation and fault signal, low-water signal

Interfaces

  • Potential-free contacts for SBM/SSM collective operation and collective fault signals
  • Protection against low water level via contact
  • External On / Off via contact for deactivation of the system automatic mode
