How do Rotary Vane pumps work?
Rotary vane pumps work by having a rotor with two adjusting vanes continuously rotating and exhausting air or any other molecules in the occupied space. The four stages which a rotary vane pump undergo are shown below:

Single Stage vs Two Stage Vacuum Pump:
BVV VE Series pumps are a Rotary Vane Pump style that come in either Two Stage or Single Stage. Two stage pumps have two rotors and two sets of vanes that work together to full pull a medium vacuum (1st stage) and then pull a better vacuum (2nd stage). Two stage pumps are used to pull a deeper vacuum when compared to single stage pumps. Our Best Value Vacs VE115 comes as a single stage vacuum pump that outperforms other industry vacuum pumps.

This unit is intended for LEGAL purposes only, to be used in accordance with local laws and ordinances.
Use only in well-ventilated areas!

• Customers using solvents such as stabilization resins (MinWax™, Gator Venom™ etc.), alcohol and other polar solvents must use the vacuum pumps in conjunction with a cold trap for evacuations in excess of 5 minutes. (Excludes Cactus Juice™)
• If the consumer is using the pump for prolonged periods of time exceeding 5 minutes we require that a cold trap is used or the pump warranty is void.
• These stabilization resins have the ability to break down the internal components of the pump that are plastic resulting in a seized motor voiding all warranties.
• When evacuation exceeds 5 minutes these solvents begin to vaporize and then re-condense in the vacuum pump reservoir. Once enough solvent re-condenses in the pump displacing the oil the plastic internal components may begin to warp, melt or seize. The use of a cold trap will condense the vapors prior to making their way to the vacuum pump preventing pump damage due to excessive use. Furthermore, Minwax Wood Hardener™ is not to be used with any vacuum pumps, EVER. (A seized motor will result within the first use.)
• To prevent these issues from happening to your process, change the Oil after each vacuum pump use, Even if the use time is only 5min.
