Classic circulation pumps for circulation of water or glycol-containing liquids for various heating systems (single- or dual-pipe heating systems, floor-heating systems, in mixing circuits of large heating systems).
BASIC / BASIC PRO pumps are equipped with a rotor, isolated from a stator by a leakproof sleeve, i. e. pump and motor become a common node without shaft sealings, using only two sealing gaskets. Bearings are lubricated with drained liquid.
