Circulation pump GEB32-8-180N

with PWM control, energy efficient

The GEB32-8-180N circulation pump is energy efficient and equipped with a synchronous motor with a permanent magnet rotor. It is intended for the circulation of water or glycol-containing liquids in heat pumps, as well as in adjustable heating systems, including variable flow systems.

Avantaje și caracteristici

• Operating modes:
  • Fixed speed (n-const).
  • Automatic modes:
    • Δp-v (proportional pressure).
    • Δp-c (constant pressure).
    • Signal control PWM from the heat pump controller ALTAL.
    • Water flow measurement with information display on the control panel.
    • Water flow control (with sensor).
  • Switching modes is done with a single button on the front panel of the pump.
• Construction:
  • The universal impeller allows easy replacement of most Grundfos circulation pump models.
  • Anti-corrosive surface with cataphoresis coating.
  • Ceramic shaft and bearing for durable operation.
  • Status indicator and release screw on the front panel.
  • Front connection for power supply, for ease of assembly, including for installation inside boilers.
