Pump for circulating hot water
in closed and pressurized or open tank systems. Also suitable
for solar power systems. single body comprising bronze hydraulic
unit and wet rotor motor . Die-cast aluminum motor casing Techno
polymer impeller. tempered stainless steel driving shaft mounted
on graphite bearings lubricated by the pumped liquid stainless
steel protective rotor sleeve, stator sleeve and closing flange. |
|
Two-pole asynchronous motor
with squirrel cage rotor designed to work at three speeds, by means of a
special selector located on the terminal board, in order to adapt the
operation of the circulator to the characteristics of the system. |
|
An automatic clapet type valve
is incorporated into the delivery mouth of the twin version in order to
prevent water from recirculating while the unit is not working. No
overload protection required. |
