Execution
Energy saving variable speed circulating pump driven by a permanent magnet synchronous motor (pm) controlled by on board inverter.
Applications
The energy-efficient circulation pump is designed for water circulation in heating systems.
Underfloor heating systems
Single-pipe systems
Two-pipe systems
Pumping liquid:
Clean, non-aggressive and non-expolosive liquids, not containing solid particles, fibers or mineral/vegetable oil
In heating systems, water must meet the requirements of accepted standards of water quality in heating systems.
