Oil-sealed
Piston Pump
Basai Piston vacuum pump is an positive displacement pump that creates a vacuum by using the back-and-forth movement of a piston inside a cylinder, Piston pump’s performance is Efficient in low-to-medium vacuum regimes.

Key features
Why the Rotary Piston Pump
- Single-stage pumps with a pumping speed of 250 m3/h (147cfm) and an ultimate pressure of 0,04 mbar (0.024 Torr)
- Two-stage pumps with a pumping speed of 200 m3/h (118 cfm) and an ultimate pressure of 5•10-4 mbar (3•10-4 Torr)
- Withstanding operation characterized by severe repetition.
- Stable and continuous operation at high pressures (low vacuum zones).
- Easy to make an inspection and maintain the exhaust valve storage
- Effective oil lubrication system for smooth and reliable operation.
- Easily maintained shaft sealing assembly.
