Tender text

Vertical version of highly efficient high-pressure multistage centrifugal pump with in-line connections, IEC motor with motor efficiency class IE5 and integrated, air-cooled frequency converter. The integrated frequency converter enables variable speed, pressure and PID control.

Control modes

  • Speed control: Manually via Green Button or an external signal
  • Constant or variable pressure: Pressure control via sensor, setpoint configuration via Green Button or external signal
  • 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 offers various protective functions including overload protection, low-water recognition as well as safeguards for mains under or overvoltage, high ambient temperature, phase failure, blocked pumps and short-circuits. Error messages are output to 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:

  • Voltage output (+24 V) with max. contact strength of 60 mA
  • Potential-free collective run and fault signals
  • External On/Off mode.
  • Slot for Wilo-IF modules Modbus, BACnet, CAN, PLR, LON for connection to the building automation

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 use in water distribution and boosting, industrial circulation systems, process water circulation systems 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 and highly efficient 2D/3D hydraulics (with flow and degassing optimisation)
  • Corrosion-resistant impeller, guide vane and stage housing
  • Hydraulics with flow and degassing optimisation
  • Pump housing optimised for volume flow and NPSH
  • Easy maintenance design
  • Potable water approval for pumps with stainless steel parts that come in contact with the fluid (EPDM version)

Scope of delivery

  • Wilo-Helix VE high-pressure multistage centrifugal pump
  • Installation and operating instructions

Notes on the design

  • The Helix VE series is equipped with a user-friendly mechanical seal (X-Seal) in a cartridge design and an easy maintenance standard seal or a standard mechanical seal. Different shaft seal versions and rubber material available on request.
  • The spacer coupling enables the mechanical seal to be replaced quickly and easily without removing the motor (from 5.5 kW and higher).
  • Round DIN counter flange made of grey cast iron or stainless steel, screws, nuts and gaskets are available as accessories.
  • Optional plug-in IF module
  • Sensors are available as accessories.
  • Bypass sets are available as accessories.
