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

Product detail:

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, and 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, and 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)
