Profile: Myers Vacuum Repair Services, Inc. specializes in vacuum systems. Our product line includes vacuum stills, pumps, gauges and sensor tubes, thermistor sensor and vacuum pot degasser. Our KSM 200 oil diffusion ejector is featured with high throughput over wide range 300 liters / second from 10-2 to 10-4 torr range, efficient heat transfer, replaceable heaters, fast pump down times and cooling equipments. The KSM-200 is a three stage, non-fractionating diffusion-ejector pump. It is equipped with 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 rugged electronics are designed for longevity and occasional accidental misuse. The two analog scales allow the user to take vacuum measurements from atmosphere to 1x10-3 torr. A separate meter scale for the 1 to 100 milliliter range provides increased readability in this critical area. Our gauge has a leak detection unit, a recorder to measure the pressure range. The entire gauge is nickel plated steel with a maximum bake out temperature of sensor envelope.
