Segregated multi fluid pump head assembly

Abstract

A high pressure pump head assembly capable of pumping multiple fluids on demand and under pressure for desired applications in association with a single high pressure pump.

1 .- 5 . (canceled) 
     
     
         6 . A pump head assembly, comprising:
 a housing defining at least two segregated pressure chambers;   a respective inlet check valve associated with each pressure chamber;   a respective outlet check valve associated with each pressure chamber;   a first conduit for fluid from a first tank to enter one of the pressure chambers through one of the respective inlet check valves; and   a second conduit for fluid from a second tank to enter another of the pressure chambers through another one of the respective inlet check valves;   wherein the first tank is configured for filling with first fluid and the second tank is configured for filling with a second fluid different from the first fluid; and   wherein the head assembly is configured for connection to one high pressure pump so as to selectively pump the first fluid into one of the pressure chambers and the second fluid into another of the pressure chambers, and to selectively pump the first fluid out of the head assembly through one the respective outlet check valves and the second fluid out of the head assembly through another of the respective outlet check valves.   
     
     
         7 . The pump head assembly of claim  1  wherein the outlet check valves are operatively connected to an apparatus to apply pressurized fluid to a surface. 
     
     
         8 . The pump head assembly of claim  1 , wherein the high pressure pump comprises either a piston pump or a plunger pump. 
     
     
         9 . A pump head assembly, comprising:
 a housing defining at least three segregated pressure chambers;   a respective inlet check valve associated with each pressure chamber;   a respective outlet check valve associated with each pressure chamber;   a first conduit for fluid from a first tank to enter the first one of the pressure chambers through the first one of the respective inlet check valves;   a second conduit for fluid from a second tank to enter the second one of the pressure chambers through the second one of the respective inlet check valves;   a third conduit for fluid from a third tank to enter the third one of the pressure chambers through the third one of the respective inlet check valves;   wherein the first tank is configured for filling with first fluid, the second tank is configured for filling with a second fluid different from the first fluid, and the third tank is configured for filling with a third fluid different from the first and second fluids; and   wherein the head assembly is configured for connection to one high pressure pump so as to selectively pump the first fluid into the first one of the pressure chambers, the second fluid into the second one of the pressure chambers, the third fluid into the third one of the pressure chambers, and to selectively pump the first fluid out of the head assembly through the first one the respective outlet check valves, the second fluid out of the head assembly through the second one of the respective outlet check valves, and the third fluid out of the head assembly through the third one of the respective outlet check valves.   
     
     
         10 . The pump head assembly of  claim 9  wherein the outlet check valves are operatively connected to an apparatus to apply pressurized fluid to a surface. 
     
     
         11 . The pump head assembly of  claim 9 , wherein the high pressure pump comprises either a piston pump or a plunger pump.
