Technical data
Tender text

Compact pressure boosting system, for direct or indirect connection. Consisting of a non self-priming, vertically-mounted stainless steel high-pressure centrifugal pump in a glanded version, for which the pump is fitted with a frequency converter. Ready for connection with stainless steel pipework, mounted on a base frame, 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, 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 advantages

  • Heavy-duty system with Helix VE series stainless-steel high-pressure multistage centrifugal pumps and air-cooled integrated frequency converter
  • High-efficiency pump hydraulics in conjunction with IE4-equivalent standard motors
  • Superproportionally large frequency converter control range from 25 Hz up to a maximum of 60 Hz (version dependent)
  • Integrated full motor protection via PTC
  • Integrated dry-running detection with automatic cut-out in event of low water via performance characteristics of the motor control electronics
  • Customized systems on request


  • One pump of the Helix VE 2 to Helix VE 52 series with IE4-equivalent standard motor and infinitely variable auto control with integrated frequency converter
  • Base frame made of galvanised steel, with height-adjustable vibration absorbers for insulation against structure-borne noise
  • Parts that come in contact with the fluid are corrosion-resistant
  • Pipework stainless steel

On pressure side:

  • Shut-off valve
  • Non return valve
  • Diaphragm pressure vessel 8 l, PN 16
  • Pressure sensor 4..20mA
  • Pressure gauge

On suction side

  • Pressure sensor 4..20mA
  • Pressure gauge

Set up on galvanised base frame with height-adjustable vibration absorber with diaphragm pressure vessel (volume 8 l) including flow fitting in accordance with DIN 4807, integrated non-return valve, pressure sensors (4 - 20 mA) and pressure gauge for the automatic system control with p = constant or p = variable function. Delivery head setpoint infinitely variable by means of one-button operation available on the frequency converter. Automatic zero-volume detection and deactivation. Built-in motor protection by means of electronic current monitoring.

With LCD display for status and actual pressure display, as well as one-button operation for configuring the pressure level and all setpoint defaults, as well as potential-free contacts for the collective fault and collective run signals.

Wired and ready for connection and piped with shut-off valve on the pressure side mounted to the base frame.
