WebDiffusion pumps cannot discharge directly into the atmosphere, so a mechanical forepump is typically used to maintain an outlet pressure around 1 mTorr. These Varian model HS-32 high vacuum, high throughput diffusion pumps are new and can be ordered with either a 3-phase 240, 415 or 480 VAC heaters. ... Web2. Diffusion Pump Figure 3: Diffusion Pump (Capable of reducing system pressure to the region of 10-7 torr[1]). A diffusion pump has a maximum pressure against which it can exhaust; this is usually in the mtorr region. (The maximum exhaust pressure is also known as the "tolerable forepressure".) The mechanical pump
Diffusion pumps use a high speed jet of vapor to direct gas molecules in the pump throat down into the bottom of the pump and out the exhaust. They were the first type of high vacuum pumps operating in the regime of free molecular flow, where the movement of the gas molecules can be better … See more In the late 19th century, most vacuums were created using a Sprengel pump, which had the advantage of being very simple to operate, and capable of achieving quite good vacuum given enough time. … See more The steam ejector is a popular form of pump for vacuum distillation and freeze-drying.
