Highly efficient and compact pressure-boosting system with break tank for system separation in accordance with EN 1717 for indirect connection. Consisting of break tank, float valve, float switch as dry-running protection signal transmitter and a non self-priming, vertical stainless steel high-pressure multistage centrifugal pump in glanded version of the Helix VE series. Ready for connection with pipework mounted on a PE base frame, including air-cooled integrated frequency converter with all of the 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, firefighting 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 benefits

• Easy operation and configuration thanks to Green Button with blocking function and display
• WRAS/KTW/ACS approval of the pump for all parts that come in contact with the fluid (EPDM version)
• Highly efficient pump hydraulics from the Helix VE series in conjunction with IE4 IEC standard motors and continuous auto control with integrated frequency converter
• Disproportionately 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
• Parts that come in contact with the fluid are corrosion-resistant
• Hydraulics of entire system are pressure-loss optimised
• Customized systems on request

Equipment/function

• One pump of the Helix VE series, with IE4 equivalent standard motor and continuous auto control with integrated frequency converter
• Base frame made of polyethylene (PE)
• Shut-off device on the pressure side
• Non-return valve on the pressure side
• 8 litre diaphragm pressure vessel, PN 16 including throughflow fitting in accordance with DIN 4807, pressure side
• Pressure switch (6/10/16 bar), pressure side
• Pressure gauge, pressure side

Control modes

• Constant or variable pressure: Pressure control with sensor, setpoint adjustment with Green Button or by means of external signals
• PID control: other constant control variables (temperature, volume flow, pressure…) with sensor, setpoint adjustment with Green Button, by means of external signals

The electronic module provides various protective functions. This includes:

• Overload protection
• Detection of low water
• Network undervoltage or overvoltage
• Ambient temperature too high
• Missing phase
• Blocked pump
• Short-circuit

Error messages are issued on the display.

Input:

• In1 : Input sensor signal 4 – 20 mA, 0 – 10 V, 0 – 20 mA or 2 – 10 V
• In2 : Input setpoint 0 – 20 mA, 0 – 10 V, 4 – 20 mA or 2 – 10 V

Output:

• + 24 V voltage output with max. contact strength of 50 mA
• Potential-free collective fault and run signal
• External On/Off mode. IR communication
• Plug-in position for Wilo IF modules Modbus, BACnet, CAN, PLR, LON for connection to the building automation

The pump is suitable for water supply, water distribution and pressure boosting, industrial circulation systems, process water and closed cooling circuits. It can also be used in washing systems as well as for irrigation.
