Mibay H / 2H Rotary Piston Vacuum Pumps

Rotary piston (sliding-valve) vacuum pumps are a rugged, long-life choice for rough vacuum on reactors, dryers, distillation, degassing and as backing for Roots boosters. They handle condensable vapour better than vane pumps.

The table below is the exporter's current programme: H (single-stage) and 2H (two-stage). Send the model and duty — we confirm capacity, motor and flanges against your process and quote with an outline drawing.
