Recommended standard receiver tank dimensions: Diameter: 8¨/ DN200Length: 580 mm / 22.8 inchIf a receiver tank is not available, a standard pipe (size 3¨/ DN80) can be used as condensate reservoir.Use the following pipe length:
Features 1. Small compact pumping trap for condensate recovery.2. As there is no electricity needed to return the condensate, the
pumping trap can be used in hazardous areas.3. The pumping trap will work with a low filling head of only 120 mm.4. Air or saturated steam can be used as motive medium.5. The internal parts are manufactured of high quality stainless steel.
A special spring snap mechanism between the motive medium inlet valve and the venting valve secures a long life time of the internal mechanism.
Applications- Condensate return from low pressure installations- Condensate return to places located higher than the condensate
vessel- Condensate return from vacuum system

Steam Traps
Pumping Trap SERIES G
GL81 Features 1. Pumping trap for the recovery of large condensate amounts.2. As there is no electricity needed to return the condensate, the pumping trap
can be used in hazardous areas.3. The pumping trap will work with a low filling head of only 150 mm.4. Air or saturated steam can be used as motive medium.5. The internal parts are manufactured of high quality stainless steel. A special
spring snap mechanism between the motive medium inlet valve and the venting valve secures a long life time of the internal mechanism.
Applications- Condensate return from low pressure installations- Condensate return to places located higher than the condensate vessel- Condensate return from vacuum system
