Circulation pump SPM25-4-130A

Energy-efficient SPM25-4-130A circulation pump, 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.

Circulation pump SPM25-4-130A. Advantages and features

• Operating modes:
  • Fixed speed (n-const).
  • Automatic modes:
    • Δp-v (proportional pressure).
    • Δp-c (constant pressure).
    • Signal control SHIM 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 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:
  • Support for external SHIM signal control (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.

Compatible accessories (to be ordered separately):

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