Series description

Special features/product advantages

  • Heavy-duty system featuring stainless steel high-pressure multistage centrifugal pump from the Helix EXCEL series with integrated frequency converter from 25 Hz to a maximum of 60 Hz
  • High-efficiency EC motor (energy efficiency class IE5 in accordance with IEC 60034-30-2
  • Pressure-loss optimised overall system with high-efficiency pump hydraulics
  • Optimum load adjustment of system to overall system through extra control mode Δp-v
  • Improved monitoring and leakage detection via optional interface with SCADA connection
  • Maximum degree of control thanks to use of SCe control device with LCD display, simple navigation and setting using rotary knob
  • Integrated dry-running detection with automatic deactivation via the motor control electronics

Design type

Highly efficient water-supply unit (non self-priming) ready for connection with 2 to 4 vertically arranged Helix EXCEL stainless steel high-pressure centrifugal pumps switched in parallel; each pump is equipped with an integrated air-cooled, high-efficiency frequency converter and an EC motor, including Smart Controller SCe. Valves and sensors are protected for safe and reliable installation

Application

  • Fully automatic water supply and pressure boosting in residential, commercial and public buildings, hotels, hospitals, department stores and for industrial systems.
  • Pumping of drinking water and 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.

Equipment/function

  • 2-4 pumps per system of the Helix EXCEL 4 to Helix EXCEL 52 series, with high-efficiency EC motor and variable speed control via integrated frequency converter on each pump
  • Automatic pump control via Smart Controller SCe
  • Parts that come in contact with the fluid are corrosion-resistant
  • Base frame made of 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
  • Diaphragm pressure vessel 8 l, PN16, pressure side
  • Pressure sensor, pressure side
  • Pressure gauge, pressure side
  • Removable cover for protection of system components (not for Helix EXCEL 52 series)
  • Optional low-water cut-out switchgear with pressure gauge, suction side

Scope of delivery

  • Factory-mounted, connection-ready pressure boosting system checked for functionality and impermeability
  • Packaging
  • Installation and operating instructions

Description/construction

  • Base frame: galvanised steel, with height-adjustable vibration absorbers for comprehensive insulation against structure-borne noise as well as an integrated lifting device; other versions on request
  • Pipework: complete pipework made of stainless steel, suitable for the connection of all conventional piping materials; the pipework is dimensioned according to the overall hydraulic performance of the pressure boosting system
  • Pumps: 2 to 4 pumps parallel-switched of the Helix EXCEL 4 to Helix EXCEL 52 series. The air-cooled frequency converters mounted on the pump motor enable infinitely variable control between 25 Hz and a maximum of 60 Hz for all pumps of this series. All pump parts which come into contact with the fluid are made of stainless steel; other versions on request. KTW/WRAS/ACS approval for all parts that come in contact with the fluid
  • Valves: Each pump is fitted on the suction and pressure side with a standard shut-off valve with DVGW approval mark and on the pressure side with a DVGW/KTW-approved non-return valve.
  • Diaphragm pressure vessel: 8 l/PN16 arranged on the discharge side with a diaphragm made of butyl rubber, with DVGW/KTW approval, completely safe in accordance with food safety laws; for testing and inspection purposes, with a shut-off ball cock with drain and throughflow fitting with DVGW/KTW approval in accordance with DIN 4807
