When cold traps are provided just above the pump throat so that oil vapors passing this point are condensed and returned to the pump, the pump will then be able to reach a lower pressure than would otherwise be possible. Vacuum cold traps condense harmful vapors into a liquid before they can reach and damage your vacuum pumps. A tube port is a more permanent fixture for a vacuum trap. In either case, severe loss of efficiency and poor vacuum levels result. Rotary vane vacuum pumps are oil-sealed pumps that feature sliding vanes that rotate in the cavity of the pump. After selecting a cold vacuum trap, the next factor that must be considered is whethera liquid nitrogen or dry ice trap is needed. Plot No. No. 5 year bumper to bumper warranty! Due to hydrogen bonding, water has a very low vapor pressure, and so most substances will have a higher vapor pressure than water. This is due to the fact that they allow the operator to avoid coming in contact with the effluent.
