Technical Features
Design
High-efficiency connection-ready water-supply unit (non-self-priming) with one vertically arranged stainless steel high-pressure multi-stage centrifugal pump in glanded version of the Helix VE series.
Application
- Fully automatic water supply in inlet mode, either from the public water supply network or from a tank
- 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
One pump from the Helix VE 2 to Helix VE 52 series, with IE5-equivalent standard motor and speed control with integrated frequency converter, mounted on height-adjustable, zinc-coated steel base frame.
All components in contact with fluid are corrosion-resistant.

Helix VE 22 to Helix VE 52
-
- Impellers, guide vanes, stage housing made of stainless steel 1.4307
- Pump housing made of cataphoretically coated EN-GJL 250 grey cast iron
- Shaft of stainless steel 1.4057
- 1.4404 shaft protection sleeve
- O-Ring gaskets made of EPDM (FKM gasket on request)
- Pipework made of 1.4301 stainless steel
Construction
- Base frame: galvanised steel, with height-adjustable vibration absorbers for comprehensive insulation against structure-borne noise
- 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: 1 pump of the series Helix VE 2 to Helix VE 52 is used. 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: The 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, arranged on the discharge side, for control of the frequency converter
