Short text
Electronically controlled, non-self-priming high-pressure multistage centrifugal pump in vertical design, with in-line connections
Tender text
Highly efficient high-pressure multistage centrifugal pump in vertical design with in-line connections, IE4-Level-IEC motor and integrated, air-cooled frequency converter. The integrated frequency converter enables variable speed, pressure and PID control. Control modes *"Speed control" : Manually with green button or via external signals *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. They include overload protection, the detection of low water, mains undervoltage or overvoltage, high ambient temperature, missing phases, blocked pumps and short-circuits. 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 signals *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 shaft and the motor shaft of the motor are connected by means of a clamp coupling. A separate lantern roller bearing ensures optimum admission of axial thrusts. Special, permanently attached lifting eyes enable easy pump installation. The pump is suitable for water supply, water distribution and pressure boosting, industrial recirculation systems, process water and closed cooling circuits. It can also be used in washing systems as well as for irrigation. Special features/product advantages *Easy operation and configuration thanks to green button with blocking function and display *Efficiency-optimised, laser-welded 2D/3D high-efficiency hydraulics (flow and degassing optimised) *Corrosion-resistant impellers, guide vanes and stage housings *Flow and degassing-optimised hydraulics *Flow and NPSH-optimised pump housing *Easy-maintenance design *Drinking water approval for pumps with parts that come in contact with the fluid made of stainless steel (EPDM version) Scope of delivery *Wilo -Helix VE high-pressure multistage centrifugal pump *Installation and operating instructions Design notes *The Helix VE series is equipped with a user-friendly mechanical seal (X seal) in cartridge design and a standard gasket. *For pump versions PN16 and PN25, round counter flanges in cast iron or stainless steel, screws, nuts and gaskets are available as accessories *The spacer coupling makes it possible to quickly and easily exchange the mechanical seal without removing the motor (motors starting from 5.5 kW). *Optional plug-in IF-Modules *Sensors are available as accessories. *Bypass sets are available as accessories.
