1. Oil Contamination: Many rotary vane pumps use oil for lubrication and sealing, which can contaminate the catalytic process if not properly managed. 2. Wear and Tear: The vanes and rotor can wear over time, especially when pumping abrasive or corrosive fluids. 3. Limited Pressure Range: While they are excellent for creating high vacuums, rotary vane pumps may not be suitable for applications requiring extremely high or low pressures.
