Siemens Whole Shop liquid ring vacuum pump system. Massive! MUST SELL Make Offer

Description

When Boeing moved out of their Wichita facility I bought many items they chose to part with vs moving to Seattle.  Everything I bought that day was in daily service at that time and so far, everything I have tested, has worked perfectly.
As you can imagine, Boeing goes beyond the extra mile to properly maintain machinery so I am pretty sure this unit was very well taken care of and is very likely in good working order. I just don't have any way of demonstrating it.
I do see a pipe large (6"?) fitting connection on top that appears to need a new gasket or possibly more. It looks like it will leak if not addressed. Otherwise, this machine looks good.
Sorry, but I know practically nothing about these vacuum units. I am happy, however, to answer questions the best I can,
----  * (my ph # is in the last pic),  ----   and to provide you with additional pics or details from the numerous ID plates.
This giant vacuum pump system also comes with three BIG wall mounted electrical control boxes that look like new.
Make me a reasonable offer and it's yours. I am long retired and have recently sold my warehouse, so this big thing has to go!
I can forklift load into/onto any truck or trailer you dispatch. Crating, if needed, will be extra.
Thanks
