Abstract

A multi-pump apparatus can include a pump unit including two or more motorized pumps, wherein each of the two or more motorized pumps can include a stator and a stator exit. The multi-pump apparatus can further include a plurality of stator exits including each stator exit of each stator of the two or more motorized pumps, and a group of adjustable hoses, wherein the two or more motorized pumps of the pump unit are operable to inject a dense fluid from the plurality of stator exits through the group of adjustable hoses.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A multi-pump apparatus, comprising:
 a pump unit comprising at least two motorized pumps, wherein each of the at least two motorized pumps includes a stator and a stator exit;   a plurality of stator exits including each stator exit of each stator of the at least two motorized pumps; and   a plurality of adjustable hoses, wherein the at least two motorized pumps of the pump unit are operable to inject a dense fluid from the plurality of stator exits through the plurality of adjustable hoses.   
     
     
         2 . The multi-pump apparatus of  claim 1  wherein the pump unit including the at least two motorized pumps provides for a multiple discharge. 
     
     
         3 . The multi-pump apparatus of  claim 1  wherein the pump unit including the at least two motorized pumps provides for a placement of the dense fluid. 
     
     
         4 . The multi-pump apparatus of  claim 1  wherein the pump unit including the at least two motorized pumps provides for a multiple discharge and a placement of the dense fluid. 
     
     
         5 . The multi-pump apparatus of  claim 1  wherein the at least two motorized pumps of the pump unit are operable to inject the dense fluid from the plurality of stator exits through the plurality of adjustable hoses. 
     
     
         6 . The multi-pump apparatus of  claim 3  wherein the dense fluid is injected through the plurality of adjustable hoses into a cavity located between a base and the pump unit. 
     
     
         7 . The multi-pump apparatus of  claim 1  wherein the at least two motorized pumps of the pump unit are operable to inject the dense fluid from the plurality of stator exits through the plurality of adjustable hoses into a cavity located between a base and the pump unit. 
     
     
         8 . The multi-pump apparatus of  claim 1  wherein the dense fluid comprises an epoxy grout material. 
     
     
         9 . The multi-pump apparatus of  claim 7  wherein the base comprises a concrete base. 
     
     
         10 . A method of operating a multi-pump apparatus, comprising:
 providing at least two motorized pumps of a pump unit; and   operating the at least two motorized pumps of the pump unit to inject a dense fluid from a plurality of stator exits through a plurality of adjustable hoses, the at least two motorized pumps including a stator and a stator exit, the plurality of stator exits including each stator exit of each stator of the at least two motorized pump.   
     
     
         11 . The method of  claim 10  wherein the at least two motorized pumps provides for a multiple discharge. 
     
     
         12 . The method of  claim 10  wherein the at least two motorized pumps provides for a placement of the dense fluid. 
     
     
         13 . The method of  claim 10  wherein the pump unit including the at least two motorized pumps provides for a multiple discharge and a placement of the dense fluid. 
     
     
         14 . The method  claim 10  wherein the at least two motorized pumps of the pump unit are operable to inject the dense fluid from the plurality of stator exits through the plurality of adjustable hoses. 
     
     
         15 . The method of  claim 14  wherein the dense fluid is injected through the plurality of adjustable hoses into a cavity located between a base and the pump unit. 
     
     
         16 . The method of  claim 10  wherein the at least two motorized pumps of the pump unit are operable to inject the dense fluid from the plurality of stator exits through the plurality of adjustable hoses into a cavity located between a base and the pump unit. 
     
     
         17 . The method of  claim 10  wherein the dense fluid comprises an epoxy grout material. 
     
     
         18 . The method of  claim 16  wherein the base comprises a concrete base. 
     
     
         19 . A multi-pump apparatus, comprising:
 a pump unit comprising at least two motorized pumps, wherein each of the at least two motorized pumps includes a stator and a stator exit;   a plurality of stator exits including each stator exit of each stator of the at least two motorized pumps; and   a plurality of adjustable hoses, wherein:
 the at least two motorized pumps of the pump unit are operable to inject a dense fluid from the plurality of stator exits through the plurality of adjustable hoses; 
 the pump unit including the at least two motorized pumps provides for a multiple discharge and a placement of the dense fluid; and 
 the at least two motorized pumps of the pump unit are operable to inject the dense fluid from the plurality of stator exits through the plurality of adjustable hoses into a cavity located between a base and the pump unit. 
   
     
     
         20 . The apparatus of  claim 19  wherein the dense fluid comprises an epoxy grout material and the base comprises a concrete base.
