The pumps SOGEVAC SV 10 B,<br />
SV 16 B and SV 25 B are equipped<br />
depending of their Part No. without or<br />
with a permanent gas ballast.<br />
The pumps SOGEVAC SV 16,<br />
SV 25, SV 40 B, SV 65 B, SV 100 B,<br />
SV 500 B(F), SV 630 B(F) and<br />
SV 750 B(F) are equipped depending<br />
of their Part No. without or with a<br />
manual, permanent or solenoid gas<br />
ballast.<br />
The SV 1200 is equipped as standard<br />
with two manual gas ballast valves.<br />
The gas ballast valve may also easily<br />
be retrofitted to the SV 40, SV 65,<br />
SV 100, SV 200 and SV 300 (either<br />
standard, large or solenoid).<br />
The thermal switch is installed at the<br />
hottest point of the pump module. It<br />
responds as soon as the temperature<br />
of the pump exceeds the maximum<br />
operating temperature. This accessory<br />
is recommended when operating the<br />
pump at high ambient temperatures.<br />
Ratings for the normally closed<br />
contact:<br />
25 V AC, 50 Hz - 5 A<br />

The SV 500, SV 630, SV 750 B(F) and<br />
SV 1200 include this switch as a<br />
standard.<br />
