Product detailed description

GRUNDFOS SOLAR 25-40 circulation pump for solar systems

The specialized GRUNDFOS SOLAR 25-40 circulation pump is suitable for circulating water in solar heating systems in households.  The circulation pump ensures circulation of the medium (e.g. a mixture of water and glycol) in systems with solar collectors. GRUNDFOS SOLAR 25-40 pumps have a rotor encapsulated by an insulating can, meaning the pump and motor form a compact unit with no stuffing box, fitted with only two sealing rings.

The GRUNDFOS SOLAR range of pumps is specially designed for use with standard high-flow solar collectors. The GRUNDFOS SOLAR 25-40 pump has a long service life and excellent resistance to extremely high operating temperatures.
