We recommend to install the dust filter horizontally. This ensures that when
removing the filter no particles fall into the intake port.
When pumping vapors, we recommend installing condensate traps on the
intake and exhaust sides
The intake must be installed in such a way to avoid condensates flowing into
the pump.
Exhaust Side
The SOGEVAC pumps have integrated exhaust filters which, even at a high
®
gas throughput, trap the oil mist and guarantee exhaust gas free of oil mist. If
the exhaust filters are clogged, the by pass opens at 1.5 bar, (absolute pres-
sure), and the filters are bypassed. As a result, the proportion of oil in the
exhaust gas as well as the pump's oil consumption will rise. Installing new
exhaust filters will correct this problem. (See § 5.4).
Check in the individual case whether an line is necessary and/or prescribed.
Volatile substances will pass through the filter. Depending on the process
gas, we recommend connecting an exhaust line ; this is always necessary
when the exhaust gases are dangerous.
The maximum exhaust pressure must neither exceed 1.15 bar absolute
(0.15 bar relative), nor fall under atmosphere pressure minus 15 mbar.
Exhaust flanges
The SV630 B (Euro-version) and the SV750 B are not equipped with outlet
■
flange (only hole Ø 80). An outlet pipe can be connected through accessory :
Exhaust kit DN 100 PN10, 100 ISO K : Cat. Nr. 9 714 38 540.
SV630 BF is in standard equipped with outlet flange DN 100 ISO K.

The cross-section of the exhaust line should be at least the same as the
pump's exhaust port. If the exhaust line is too narrow, overpressure or
overheating may occur in the pump.
Before installing the exhaust line, remove the exhaust-flange plate and
ensure that the exhaust demister(s) are secured tightly in place. They
sometimes loosen during shipping and installation. A loose demister results
in exhaust smoke during start-up and operation. Install the exhaust line with
a downward slope to prevent condensate from flowing back into the pump. If
this is not possible, we strongly recommend installing a condensate trap.
Never operate the pump with a blocked or restricted exhaust line. Before
start-up, ensure that any blinds or similar shut-off devices in the exhaust line
on the pressure side are opened and that the exhaust line is not obstructed.
Exhaust pipe material must be resistant to pumped gases.
