Circulation pump SPM25-6-130A

Circulation pump SPM25-6-130A

Energy-efficient SPM25-6-130A circulation pump, equipped with a synchronous motor with a permanent magnet rotor. Intended for the circulation of water or glycol-containing liquids in heat pumps, as well as in adjustable heating systems, including variable flow systems.   Circulation pump SPM25-6-130A. Advantages and features:

• 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:
  • Universal impeller allows easy replacement of most Grundfos circulation pump models.
