Additional Information

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.

Pump Warranty Information

• Customers using solvents such as stabilization resins (Cactus Juice™ 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. 
• 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.
