Technical data
Tender text

Glanded twin-head pump with in-line design for pipe installation or installation on a base with built-in frequency converter for electronic control for constant or variable differential pressure (Δp-c/Δp-v), among other things.

Design:

  • Single-stage low-pressure centrifugal pump
  • Spiral housing in in-line design (suction and pressure ports with the same flanges in one line), flanges PN 16 – drilled acc. to EN 1092-2
  • Pressure measuring connections (R 1/8) for mounted differential pressure sensor (version ...-R1 without differential pressure sensor)
  • Pump housing and motor flange with cataphoretic coating as standard
  • Mechanical seal S1 recommended for water-glycol mixtures with glycol proportions up to max. 50% by volume and a fluid temperature of -20 °C up to max. +110 °C and also for oil proportions in the water-glycol mixture.

Accessories:

  • Mounting brackets for fixing to the foundation
  • IR-Monitor
  • IF module PLR
  • IF module LON
  • IF module Modbus
  • IF module BACnet
  • IF module CAN
  • Control systems VR-HVAC/CCe-HVAC/SCe-HVAC
  • Differential pressure sensor (DDG) sets 0-10 V for pumps in version ...-R1

Standard equipment:

  • One-button manual operation level for:
    • Pump On/Off
    • Setpoint and speed adjustment
    • Selecting the control mode: Δp-c (constant differential pressure), Δp-v (variable differential pressure), PID controller, n-constant (constant speed)
    • Selection of operating mode in twin-head pump operation (main/standby operation, parallel operation)
    • Configuration of operating parameters
    • Fault acknowledgement
  • Pump display for indication of:
    • Control mode
    • Setpoint (e.g. differential pressure or speed)
    • Error and warning messages
    • Actual values (e.g. power consumption, actual value of the sensor)
    • Operating data (e.g. operating hours, energy consumption)
    • Status data (e.g. status of SSM and SBM relay)
    • Device data (e.g. pump name)

Additional functions:

  • Interfaces: Control input "Overriding Off", "External pump cycling", analogue input 0–10 V, 2–10 V, 0–20 mA, 4–20 mA for constant speed (DDC) or for remote setpoint adjustment, analogue input 0–10 V, 2–10 V, 0–20 mA, 4–20 mA for actual value signal of the pressure sensor, Infrared interface for wireless communication with the operating and service unit Wilo-IR-Stick/IR-Monitor, plug-in position for Wilo IF modules for connecting to the building automation, configurable, potential-free fault and operating/ready message, interface for twin-head pump communication
  • Three-phase AC motor with frequency converter
  • Integrated dual pump management
  • Adjustable time interval for pump cycling
  • Integrated full motor protection
  • Different operating modes for heating (HV) or air-conditioning (AC) applications
  • Access disable
  • Different operation levels: Standard/service
