Gap Vax HV-57:
The unit is in process of being converted from a secondary liquid ring pump to a 14 gpm triplex water pump.  Little giant PD pump is mounted and coupled to power w/relief valve.  Piping is incomplete.  Set up for a pressure washer coil and burner.  The debris tank is 15 cu yds and has a 400 gal water tank built into the front of the tank.  Tank raises and rear gate opens to dump debris and material from cyclones and bag house.  Rear doors latches were removed and rebuilt.  Was set up to switch w/air operated valves from liquid ring pump to big vac pump.  Much of that piping and valves remains.  Removed liquid ring pump and piping are included in the sale if desired.  The main pump is a Hibon 8702 which requires 300hp to operate and is driven by a power divider after transmission.  All air operated butterfly valves for switching systems. (Liquid ring pump to main vac pump) are still in place and controlled at the main panel.  Rear door has an auger for unloading certain pelletized material (needs work).  Has a separate hyd system with tank, filter, pump and cooler with fan, for raise and lower of debris tank, open and close end of debris tank, rear door latches, aux auger, etc.  The unit was designed to handle all types of material wet or dry and filter out dust and particulates, with mufflers to quiet operation.  Filtering is by cyclones on the right side and bag house on the left side 40 60” bag filters. Full set of build spec are available for gap vac unit. 
Included with sale:
Removed liquid ring pump and piping - new weld in sections for cyclones. New seal for debris gate - if needed spare tire and wheel.
We bought this unit to rebuild, but I am old, fight health issues and don’t have the time to finish this project.  There is a lot of quality equipment on this truck.  The original owner paid just over $300,000.00 for it to be built in 2002.
 $75,000.00 as is            $70,000.00 if remove pd pump
