Tender text

Highly efficient, non-self-priming high-pressure multistage centrifugal pump in horizontal design, equipped with electronically controlled EC motor of energy efficiency class IE5 in accordance with IEC 60034-30-2.

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

Control modes:

  • Constant speed n-c: manually with green button or via external signals
  • Constant pressure p-c, constant differential pressure ∆p-c, variable pressure p-v, variable differential pressure ∆p-v: 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 functions:

  • Max. pressure limit detection
  • Min. pressure limit detection
  • Lack of water detection by suction sensor
  • Zero-flow test (open loop)
  • No-Flow Stop (closed loop)
  • Dry-running detection
  • Volume flow calculation by using differential pressure sensor
  • Pump kick
  • Error and warning codes
  • Overload protection
  • Plug-in position for Wilo CIF modules PLR, LON, BACnet MS/TP, Modbus RTU, CANopen, Ethernet Multi-protocol (Modbus TCP, BACnet/IP) for connection to the building automation
  • Green LED indicates the pump status
  • Blue LED indicates that the pump is influenced externally via an interface

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):

  • Extern OFF
  • Lack of water detection by binary input

Dual pump management (2 x single pumps)

  • Main/standby operation
  • Pump cycling main/standby operation after 24 hours or automatic fault-actuated switchover
  • Wired connection via Wilo Net

Special features/product advantages
