Diffusion Vacuum Pump
扩散真空泵
Coating plants and vacuum furnaces needing very high speed at high vacuum still rely on diffusion pumps. This range reaches 10⁻⁶–10⁻⁹ mbar at 100–50,000 L/s, with 0.3–5 kW boilers and DN 100–DN 400 inlets. It needs backing below 0.1 mbar, 1–5 L/min of cooling water and a cold trap. Tell us your chamber size.
