KSM
200
The KSM-200 is a three stage, non-fractionating diffusion-ejector pump. Three umbrella type vapor stages, positioned in the vertical column, have nozzles through which jets of vapor are emitted to entrain the gas entering the pump inlet. The compressed gas is then passed on to the ejector stage in the forearm of the pump. The pump achieves peak operating pumping speed of 300 liters/second over a range from 10-2 to 10-4 Torr and has an ultimate pressure in the 10-5 Torr range. The pump has a forepressure tolerance of .6 Torr. The pump comes equipped with standard water-cooling lines with disconnect fittings. Quench lines in the boiler provide rapid cooling of oil when systems operation is stopped. Pump has four (4) 500-watt cartridge immersion heaters which insert into wells for simplified maintenance.

The
KSM-200 is a three stage, high vacuum (10-3 to 10-4
Torr range) vapor pump designed for heavy gas load applications
such as in vacuum distillation, evaporation, vacuum arc melting,
freeze drying, impregnation and casting of metals. The pump has
no moving parts which may be corroded by the acidic nature of
the material being pumped. These pumps are used in place of mechanical
roots type blower.
