Wilo Helix2.0-VE407-1/16/E/S/3, Pressure Boosting Pump
Description
Multi-wheel vertical normal-suction pressure booster pump, equipped with built-in frequency converter. Highly efficient design with motor efficiency class IE5. Together with CIF module (accessory) prepared for connection to building automation via Ethernet, CAN, LON, BACnet or Modbus interfaces. High efficiency, normal suction pressure booster pump with vertical construction with inline connections, equipped with electronically regulated EC motor in the energy efficiency class IE5 corresponding to IEC 60034-30-2. The connection to the pump and motor shaft is made with a sleeve coupling. A separate lantern ball bearing ensures optimal access to axial force. Special fixed lifting eyes make the pump easy to install. The pump is suitable for water supply, water distribution and pressure boosting, for industrial circulation plants, process water, closed cooling circuits and heating. It can also be used in washing facilities and for irrigation.
Regulation method:
- Fixed speed n-c: manually with the green button or with the help of external signals
- Constant pressure p-c, constant differential pressure ∆p-c, variable pressure p-v, variable differential pressure ∆p-v: Pressure regulation with sensor and setpoint setting with the green button or with the help of external signals
- PID control: other constant control variables (temperature, flow, pressure...) with sensor, setpoint setting with the green button or with the help of external signals
The electronics module has various functions:
- Detection of maximum pressure limit value
- Detection of minimum pressure limit value
- Water shortage detection by suction sensor
- Zero amount test (open circuit)
- No-Flow Stop (closed circuit)
- Dry run identification
- Calculation of flow using a differential pressure sensor
- Pump exercise
- Error and warning codes
- Overload protection
- Connection point for Wilo CIF modules PLR, LON, BACnet MS/TP, Modbus RTU, CANopen, Ethernet Multi-protocol (Modbus TCP, BACnet/IP) for connection to building automation
- Green LED shows the pump status
- Blue LED indicates that the pump is controlled externally via an interface
