Busch Huckepack Vacuum Pump HO 0433-D 807
Once through oil rotary vane design.? In operation before being removed from service.? Leaks a little oil and could use a seal replacement.? Built in startup and shutdown cycle and knockout pot with emergency shutdown sensors. I believe it needs an air operated solenoid valve to function as intended.? These are industrial workhorses suitable for chemical and corrosive process streams.? ?
