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. Three-phase AC motor with frequency converter
Design:
Single-stage low-pressure centrifugal pump with one-piece shaft
Spiral housing, in-line design
PN 16 flange – drilled according 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 for water feed up to T=120 °C. A glycol admixture of 20 to 40% by vol. is permitted up to Tmax = +40 °C. Other mechanical seals or other fluids/temperatures on request.
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
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 dual pump operation (main/standby operation, parallel operation)
Configuration of operating parameters
Fault acknowledgement
Pump display for displaying:
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” (effective only in dual pump operation), analogue input 0–10 V, 2–10 V, 0–20 mA, 4–20 mA for control mode (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-Module Modbus, BACnet, CAN, PLR, LON for connecting to the building automation, configurable, potential-free fault and operating/ready message, interface for dual pump communication
Adjustable time interval for pump cycling (in dual pump mode)
Integrated full motor protection
Different operating modes for heating mode (HV) or air-conditioning mode (AC)
Access disable
Different operation levels: Standard / Service
