This is a 10 gallon electropolished pressure vessel with a Lightnin magnetic mixer in bottom of tank.  The magnetic mixer has a removable impeller in the tank with no physical shaft coming through the bottom of the tank for a perfect seal.  The gearhead motor under that tank transmits its power to the impeller with magnets.  This unit was removed from a custom made system and has little to no use on it.  We tested the motor with a DC controller and it worked well as can be seen in the test video.   A motor controller is not included but it only needs a very simple 90VDC controller to power the motor and to make the system variable speed.  

The tank is manufactured by Alloy Products Corp and it resembles their 10 gallon 316 stainless general purpose electropolished tank.  The magnteic mixer is manufactured by Lightnin and it is their MBI410 Magmixer model that was welded to the bottom of the tank by the Alloy Products Corp.
