Simplex Oil Sealed, Air Cooled,
Two-Stage Liquid Ring
Vacuum Systems
|
SelecTORR® "OA" models are oil sealed systems that totally recirculate the sealing
oil, which is cooled by an oil to air heat exchanger. This arrangement provides
all of the benefits of liquid ring vacuum pumps, without the need for sealing or
cooling water.
The system includes a two stage liquid ring vacuum pump with motor,
discharge separator with oil mist filter, gauges, and piping, all mounted on a common
base. The systems are factory assembled, tested, painted, and crated.
