Equipment/function
- 1 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
- Stainless steel 1.4301
- Shut-off valve, pressure side
- Non-return valve, pressure side
- Diaphragm pressure vessel 8 l, PN16, pressure side
- Pressure gauge, pressure side
- Optional low-water cut-out switchgear and pressure gauge, suction side

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

Consulting guide
Inlet pressure
The maximum inlet pressure (see Technical data) must be taken into account when configuring the system. The maximum permissible inlet pressure is calculated from the maximum operating pressure of the system minus the maximum pump delivery head at Q = 0.
Always observe the specifications in DIN 1988 (EN 806) when using and operating the pressure boosting system.
Pressure reducer
Fluctuating inlet pressure is compensated by the speed control integrated into the pump as long as the pressure fluctuation is not greater than the difference between the setpoint pressure value and the zero-delivery head of the single pump at minimum speed. If the pressure fluctuation is greater, a pressure reducing valve must be installed upstream of the system.
Residual-current-operated protection switch
When installing residual-current-operated protection switches in conjunction with frequency converters, bear in mind that only universal-current-sensitive residual-current-operated protection switches in accordance with DIN/VDE 0664 are to be fitted.
Wilo-WMS low-water cut-out switchgear
The series Helix VE pump being used is already equipped with an integrated dry-running detection as safety equipment for the pump.
Details about electronics/EMC
Single-pump systems up to and including 7.5 kW motor power:
- Emitted interference in compliance with EN 61000-6-3
- Interference resistance in compliance with EN 6100-6-1
Note: Systems to be used in residential buildings must be installed by personnel who have completed EMC training.
