I think @Beaker breaks down why we use dual vane rotary pumps over other pumps in this thread

Oil-Free Vacuum

Hi folks, I have an equipment/engineering question: Why is everyone using oil-sealed vacuum pumps? Vacuum pumps are among the most diverse in terms of equipment choices: rotary piston, ejectors, rotary cane, mechanical boosters, chemical dry pumps, diffusion pumps, the list is quite expansive. So why is everyone using oil-sealed, rotary cane Edwards pumps for distillation purposes? I’d love to see response and see if I can’t propose alternatives
