Trivac D 16BCS

TRIVAC B, Two-Stage Rotary Vane
The TRIVAC BCS –Production of semiconductors and
in the area of chemistry



The TRIVAC BCS pumps are oil sealed vacuum pumps operating according to the rotary vane principle . Oil which is injected into the pump chamber is used for sealing, lubrication and cool- ing purposes

The pump body is assembled from individual parts without sealing compo- nents . The parts are pinned in order to ensure easy disassembly and reassem- bly of the parts

The motor is connected to the pumping section via an elastic coupling 

In addition, the TRIVAC BCS is ready for system integration (adaptable to dif- ferent applications)
