Highly efficient, non-self-priming, high-pressure multistage centrifugal pump in vertical design with in-line connection, equipped with electronically controlled EC motor with energy efficiency class IE5 according to IEC 60034-30-2. The pump and motor shafts are connected via clamp coupling. A special lantern ball bearing ensures optimum admission of axial thrusts. Special, built-in lifting eyes allow the pump to be easily installed. The pump is suitable for the water supply, water distribution and pressure boosting, for industrial circulation systems, process water, closed cooling circuits and heating applications. It can also be used in washing systems as well as for irrigation. Control modes: *Constant speed n-c: manually with the green button or using an external signal *Constant pressure p-c, constant differential pressure ∆p-c, variable pressure p-v, variable differential pressure ∆p-v: Pressure control via sensor, setpoint configuration with the green button or using the external signal *PID control: Other constant control variables (temperature, volume flow, pressure etc.) with sensor, setpoint configuration with the green button or using the external signal The electronic module offers various functions: *Maximum pressure for limit detection *Minimum pressure for limit detection *Low-water detection through suction sensor *Zero-flow test (open circuit) *No-Flow Stop (closed circuit) *Dry-running detection *Calculation of the volume flow with the help of a differential pressure sensor *Pump kick *Error and warning codes *Overload protection *Slot for Wilo CIF module PLR, LON, BACnet MS/TP, Modbus RTU, CANopen, Ethernet Multi-protocol (Modbus TCP, BACnet/IP) for connection to the building automation *A green LED indicates pump status *A blue LED indicates that the pump is controlled externally via an interface *Access barrier Analogue input: *IN (AI 1): Input, sensor signal 4–20 mA, 0–10 V, 0–20 mA or 2–10 V *IN (AI 2): Input, setpoint 0–20 mA, 0–10 V, 4–20 mA or 2–10 V Digital input IN (DI 1): *External OFF *Low-water detection due to binary input Dual pump management (two single pumps) *Main/standby operation *Pump replacement in main/standby operation after 24 hours or automatic fault-actuated switchover *Wired connection via Wilo Net Special features/Product advantages *IE5 EC motor and integrated frequency converter combined with highly efficient Helix hydraulics *2" LCD colour display, Wilo Green Button Technology and soft button with back function. The well-arranged pump menu allows the pumps to be conveniently set up. *Analogue and digital interface and CIF module *Intelligent control with different control modes including integrated dual pump management *Efficiency-optimised, laser-welded and highly efficient 2D/3D hydraulics (with volume flow and degassing optimisation) *Corrosion-resistant impeller, guide vane and stage housing *Hydraulics with volume flow and degassing optimisation *Pump housing optimised for volume flow and NPSH *Easy maintenance design *Drinking water approval for pumps with parts made of stainless steel that come into contact with the fluid (EPDM version) Scope of delivery *Helix2.0-VE high-pressure multistage centrifugal pump *Installation and operating instructions *Helix2.0-VE 2 – 16 (PN 16 version with oval flange): Stainless steel counter flanges with the corresponding screws, nuts and gaskets Notes on the design *Depending on the version, the Helix2.0-VE series is equipped with a user-friendly mechanical gasket (X-Seal) in cartridge design as well as a standard gasket for easy maintenance or a standard mechanical seal. *For PN 16 and PN 25 version pumps, round counter flanges made of grey cast iron or stainless steel, screws, nuts and gaskets are available as accessories. *The spacer coupling enables the mechanical seal to be replaced quickly and easily without removing the motors (from 5.5 kW and higher). *Optional plug-in Wilo CIF modules PLR, LON, BACnet MS/TP, Modbus RTU, CANopen, Ethernet Multi-protocol (Modbus TCP, BACnet/IP) for connection to the building automation *Optional connection for M12 RJ45 CIF Ethernet *Sensors are available as accessories: Differential pressure set 4–20 mA and relative pressure set 4–20 mA *Bypass kits are available as accessories
