  • PRODUCT DESCRIPTION
Pump for circulating hot water in centralised domestic heating and air-conditioning systems of the closed and pressurised or open tank type. Also suitable for solar power installations. This pump combines a traditional circulator with an air separator. The system removes the air from the centre of the pump body in order to allow the air separator to work in ideal operating conditions. The air contained in the pumped liquid is guided by the flow to the separation chamber where the size of the chamber and the internal pressure difference separates it from the liquid. It is then automatically expelled through the relief valve. The air separator is only available with an ascending flow. Single body comprising a technopolymer hydraulic unit and a wet rotor motor. Bronze air separator. Die-cast aluminium motor casing. Technopolymer impeller. Tempered stainless steel driving shaft mounted on graphite brushings lubricated by the pumped liquid. Stainless steel protective rotor sleeve, stator sleeve and closing flange. Ceramic thrust bearing, E.P.D.M. "O" rings and brass air outlet cap. Two-pole asynchronous motor with squirrel cage rotor designed for three-speed operation by means of a special switch on the terminal board which automatically adapts performance in relation to system requirements. Motor self-protected for resistance. No overload protection required.
