Electronic circulation pump for water recirculation in heating and air conditioning systems in residential buildings. Efficient and reliable, equipped with a two-digit display showing the parameters. It is ideal for replacing old circulation pumps thanks to its compact dimensions and the available settings. A single button simplifies configuration by the installer. The included limescale removal cartridge keeps the motor shaft in perfect condition, preventing the formation of limescale that can be generated inside the circulation pump if there are air bubbles during the first installation.

PUMP DESIGN FEATURES Cast iron pump body with cataphoresis treatment. Technopolymer impeller. Graphite axial bearing. Brass air plug.

MOTOR DESIGN FEATURES Permanent magnet synchronous motor, stainless steel motor housing. Motor shaft and ceramic bushings. Rotor can, stator can and closing flange made of stainless steel. The motor shaft can be unblocked manually.

ELECTRONIC UNIT DESIGN FEATURES Waterproof frequency converter with IPX5 protection. Single-button configuration. You can choose from the nine available operating settings: three with proportional pressure, three with constant pressure, three with constant curve. The digital display can show power consumption in watts, instantaneous flow rate, head and the set curve. It is equipped with an automatic degassing function and protection against overload and dry running. Power connector compatible with connectors of other brands, without the need to rework the electrical connections.
