Description
Highly efficient water supply unit ready for connection (non self-priming).
-
Advantages
- Heavy-duty system featuring stainless steel high-pressure multistage centrifugal pump from the Helix VE series with integrated frequency converter with a super proportionally large control range from 25 Hz to a maximum of 60 Hz
- High energy savings due to pressure-loss optimised hydraulics and optimum load adjustment via variable pressure control (p-v) and parallel synchronous speed control
- High reliability through integrated protection functions such as overload protection, dry-running protection and WMS with automatic deactivation as well as control and leakage detection via optional interface to SCADA connection
- Maximum degree of control performance thanks to use of an SCe control device with LCD display, simple navigation and adjustment using rotary knob
- Integration into building automation via standard Modbus RTU
- Suitability for drinking water for all components in contact with the fluid

Technical Features
Design
Highly efficient water supply unit ready for connection (non self-priming). With 2 to 4 vertically arranged Helix VE series stainless steel high-pressure centrifugal pumps in glanded version switched in parallel; every pump is equipped with an integrated air-cooled frequency converter, incl. Smart Controller SCe.
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, process water, cooling water, fire water (apart from fire-fighting 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 from the Helix VE 2 to Helix VE 52 series, with IE5-equivalent standard motor and speed control via integrated frequency converter on each pump.
SCe switchgear ensures automatic control of the complete pressure-boosting system.
Complete assembly mounted on galvanised steel, height-adjustable base frame.
All components in contact with fluid are corrosion- resistant.

- 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 are used from the series Helix VE 2 to Helix VE 52, switched in parallel. 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 parts that come in contact with the fluid are made of stainless steel for the Helix VE 2 to Helix VE 16 series or of stainless steel/grey cast iron with cataphoretic coating for the Helix VE 22 to Helix VE 52 series; 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 device with DVGW approval mark and on the pressure side with a DVGW/KTW-approved non-return valve.
- Diaphragm pressure vessel: 8 l/PN 16 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
- Pressure sensor: 4 to 20 mA, located on the discharge side for controlling the central Comfort Controller SC
- Pressure indication: pressure gauge (ø 63 mm) arranged on the discharge side; additional digital indication of the discharge pressure in the alphanumeric LC display of the Smart Controller SC
- Control device/controller: The system is equipped with a Smart Controller SC as standard
