Wet Vacuum Switchable Pump System

Abstract

The wet vacuum switchable pump system includes a pump having a suction port and a pressure head port. A valving system controllably couples the suction port and the head port with a valved output port coupled to an upper port on an elongated tank laid upon its side. The valving system includes an exhaust line and a feed line. The valving system, in one modality, communicably couples the suction port and the valved output-tank whilst independently communicably coupling the pressure head port with the exhaust line. In a second modality. the head port is in communication with the valved output-tank concurrent with a second independent communication between the suction port and the feed line. The tank includes a lower port coupled to a hose and nozzle combination for suction/expulsion of fluid and slurry.

1 . A wet vacuum switchable pump system comprising: 
 a pump having a suction port and a pressure head port, said pump, when activated, respectively generating a vacuum at said suction port and a pressure head at said pressure head port;    a valving system coupled to said suction port and said head port and having an exhaust line and a feed line and an valved output port, said valving system having a first modality establishing a first communication between said suction port and said valved output port concurrent with a first independent communication between said head port and said exhaust line; and having a second modality establishing a second communication between said head port and said valved output port concurrent with a second independent communication between said suction port and said feed line;    an elongated tank laid upon its side with an upper port in its upper region and a lower port in its lower region, said upper port coupled to said valved output port; and,    a hose and nozzle combination coupled to said lower port of said tank;    wherein, when said valving system is in said first modality, said pump and tank system draws fluid therein and, in said second modality, said pump and tank system expels fluid therefrom.    
   
   
       2 . A wet vacuum pump system as claimed in  claim 1  wherein said valving system includes an operator control to change the modality of said valving system from said first modality permitting system suction via said hose and nozzle combination and said second modality permitting fluid expulsion from said hose and nozzle combination.  
   
   
       3 . A wet vacuum pump system as claimed in  claim 1  including a vertical tube mounted intermediate said lower port of said tank and said hose and nozzle combination, said vertical tube extending at least the height of said elongated tank laid upon its side to limit backflow into said tank.  
   
   
       4 . A wet vacuum pump system as claimed in  claim 1  wherein said valving system includes a first and a second valve, said first valve coupled to said suction port and defining said feed line, said first valve having a first valve output port coupled to said upper port of said tank, said second valve coupled to said head port and defining said exhaust line and having a second valve output port coupled to said upper port of said tank, valving system includes operator controls to change the modality of said first and second valves of said valving system from said first modality permitting system suction via said hose and nozzle combination and said second modality permitting fluid expulsion from said hose and nozzle combination.  
   
   
       5 . A wet vacuum pump system as claimed in  claim 4  wherein said operator controls are ganged to cause said first and second valves to change modalities concurrently.  
   
   
       6 . A wet vacuum pump system as claimed in  claim 1  including a frame upon which is mounted said elongated tank laid upon its side and said pump further mounted on said frame, said frame coupled to wheels enabling tank, pump and frame mobility.  
   
   
       7 . A wet vacuum pump system as claimed in  claim 2  including a vertical tube mounted intermediate said lower port of said tank and said hose and nozzle combination, said vertical tube extending at least the height of said elongated tank laid upon its side to limit backflow into said tank.  
   
   
       8 . A wet vacuum pump system as claimed in  claim 7  wherein said valving system includes a first and a second valve, said first valve coupled to said suction port and defining said feed line, said first valve having a first valve output port coupled to said upper port of said tank, said second valve coupled to said head port and defining said exhaust line and having a second valve output port coupled to said upper port of said tank, said operator control includes two operator controls, one for each of said first and second valves, to change the modality of said first and second valves from said first modality permitting system suction via said hose and nozzle combination and said second modality permitting fluid expulsion from said hose and nozzle combination.  
   
   
       9 . A wet vacuum pump system as claimed in  claim 8  wherein said operator controls are ganged to cause said first and second valves to change modalities concurrently.  
   
   
       10 . A wet vacuum pump system as claimed in  claim 9  including a frame upon which is mounted said elongated tank laid upon its side and said pump further mounted on said frame, said frame coupled to wheels enabling tank, pump and frame mobility.
