Okta 250 M / PPW22100F Overview:
Single-stage and multi-stage Roots pumps—also known as rotary lobe pumps, Roots blowers, or booster pumps—are technically dry-running, positive displacement vacuum pumps. In these pumps, the gearbox and bearings are isolated from the suction chamber. The lobes operate without contact, enabling technically dry operation.
Single-stage Roots pumps cannot operate directly against atmospheric pressure. To prevent excessive heating and thermal expansion of the lobes, it is essential to control the pressure differential between the suction and pressure flanges. As a result, these pumps require suitable backing pumps or cooling systems adapted to the pressure conditions. Alternatively, multiple Roots stages can be arranged in series to distribute the pressure difference across the stages.
The pumping speed of our Pfeiffer Okta Line Roots Pumps (Vacuum Boosters, Vacuum Blowers) ranges from 250 to 25,000 m³/h. They can be optimally employed for a wide variety of low and medium vacuum applications.
Okta250M Scope of Delivery:
- Roots Pump
- Seals for the connection flanges; for ISO flanges, centering rings are included
- Cover disks for the connecting flanges
- Screw kit for the connection flange
- 2 eye bolts for lifting the roots pump
