Description
Circulators for domestic hot water installations. The SAN series pumps, with three speeds and threaded fittings, are designed for the recirculation of domestic hot water, both in closed and pressurized circuits, or with an open tank, as well as in solar energy installations. Thanks to their extremely silent operation, these pumps are ideal for use in homes. The pump body (made of bronze) guarantees impeccable transport of domestic water.
