Circulation pump SPM25-9-130S

Circulation pump SPM25-9-130S

The SPM25-9-130S circulation pump is energy efficient and 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 SPM25-9-130S. 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 key on the front panel of the pump.
• Construction:
  • Universal impeller allows easy replacement of most Grundfos pump models.
  • Anti-corrosive surface with cataphoresis coating.
  • Ceramic shaft and bearing for long durability.
  • Status indicator and release screw on the front panel.
  • Front connection for power supply, for ease of assembly, including for installation inside boilers.
  • Easy access to the 4 fixing screws.
• Integrate:
  • Circulation pump SPM25‐9‐130S supports control via external PWM signal (Mini Superseal connector, bidirectional communication), allowing the pump to be integrated into systems controlled by controllers or smart homes.
  • Possibility to transmit data on the pump status (operating status, power consumed) to the external controller for precise performance management.

Circulation pump SPM25-9-130S. Basic control logic

• When the PWM signal is connected, the SPM25‐9‐130S circulation pump operation is controlled by the PWM signal.
• When there is no PWM signal, the operation of the water pump is controlled according to the internal control logic.

Compatible accessories (to be ordered separately):

• Quick connection set.
• Power adapter for connecting Superseal Molex or Superseal Volex connectors (150 mm).
• Signal cable for PWM signal (1000 mm).

Energy-efficient SPM25-9-130S circulation pump

— represents a reliable solution for efficient and economical operation of heating systems, ensuring a long service life and the possibility of integration into modern intelligent control systems.
