Pump Station Options – 2 way
A. Ball valve on the supply way (thermometer with red ring
and Scale 0-250F) with "Sola/' check ball.
B. (Ball valve on the return way (thermometer with blue
ring and scale 0-250F) with "Solar" check ball.
C. Pressure Relief Valve - The security unit, CE and TUV
approved, protects the installation from the
overpressures. It is calibrated at 6 bar, over this
pressure the security unit starts, It is also provided
with a manometer and with a connection to the
expansion vessel by a 3/4" flexible kit (optional),
see here at the right.
D. Flow meter - The flow meter allows to regulate the
flow rate to the capacity of the installation, by a 3-way
ball valve. lf the valve is closed the usual circulation
is cut off, it is possible to use the side filling tap to fill
the installation. There is also another side tap, for the
draining. The proximity of the two taps helps these
operations minimizing the distance between the
filling and the draining. The flow rate is measured
and shown by the special sliding cursor: the
measurement is immediate thanks to the proximity
to the regulation valve.
E. Circulating pump - Three speed circulating pump
with manual regulation. Thanks to the seal of the ball valves before and after the circulating pump, it can be removed
without emptying the installation.
