Busch RA 0180 C 461 ZZXX 3 phase vacuum pump, This is one of 2 pumps of this type that we have available, it was pulled from a working environment due to the closure of the Bridgestone tyre factory, in addition we also have 14 smaller Busch units of the same general type and a liquid ring unit.
I think the free air displacment of this pump is 180 cubic m/hour or around 107 CFM, its a serious vacuum pump.
This type of oil sealed vane vacuum pump is known to be very rugged, relatively easy to rebuild and has good operational life in less than ideal conditions compared to many pumps.
