ARVT Vacuum Pump

Very high volume, very low maintenance.   Evacuates 1 quart of air every 4 seconds.  Develops a minimum of 30 inches mercury vacuum.  Unlike standard vacuum pumps which are easily damaged by water vapor, and which require continual maintenance to prevent even small amounts of water incursion,  the ARVT vacuum pump remains completely unaffected by even gallons of water passing through the body of the pump.  Maintenance on this pump is very simple-  just put a quart of mineral oil at the intake of the pump.  The pump will suck the oil into its body and the pump it out within a couple of seconds.  That's it!  Originally developed by Shor R & D for the refining industry,  this pump will actually take high volumes of acid into its body without any damage whatsoever to the pump.  The ARVT pump is pneumatic and requires a minimum 1 hp compressor.
