Warning
We recommend to install the dust filter horizontally using the T-piece (3/13) or
the elbow (3/14). This ensures that when removing the filter no particles fall
into the intake port.
When pumping vapo u rs, we recommend installing condensate traps on the
intake and exhaust sides (see § 1.3).
By pumping of dangerous gases, inlet line must be tight.
No particles or liquids may enter in 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, pressure relief valves open and the filters are
bypassed. As a result, the proportion of oil in the exhaust gas as well as the
pump oil consumption rise.
This situation must be resolved by changing the exhaust filters. It is under
user’s responsability to assure maintenance on materiel to avoid any
trespassement of the limits autorised by regulations.
Check in the individual case whether an exhaust line is necessary and/or
prescribed. Volatile substances can 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.
Observe the safety precautions that apply to your application and process
gases. The pump’s exhaust port also has an internal thread . A hose can be
connected via a suitable screwing nipple (see § 1.3).
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 may
occur in the pump.
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 (see § 1.3). if several pumps are connected to
one exhaust line, ensure an adequate cross-section and a non-return valve at
the exhaust of each pump.
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 open and that the exhaust line is not obstructed.
By pumping of dangerous gases, exhaust line must be tight.
The maximum exhaust pressure must not exceed 1,15 bar (absolute). Also
reliably prevent the occurrence of any blockage in the exhaust line. Exhaust
filter, accessories and the tubing must be rated according to the maximum
throughput. The maximum throughput is equivalent to the pumping speed of
the pump.
Should a fored ventilation extraction be installed, the pressure in the exhaust
pipe shall not be lower than atm.pressure minus 50 mbar.
