Centrifugal pump

Abstract

A centrifugal pump is provided for use with fluids, gases and solids in connection with a drive shaft and a motor. The pump has a split housing and a split impeller mounted on the shaft within the housing. The housing has opposing inlet means on each side of the impeller and a discharge outlet. The impeller can be mounted on a split adapter which comes in various sizes on which the impeller can be mounted for use on various sized shafts.

What is claimed is:  
     
         1 . A self-priming centrifugal pump apparatus comprising: 
 a) a split housing having a top and bottom portion forming a front wall, a rear wall and peripheral side walls, a discharge outlet opening in said top portion and inlet means formed by said top and bottom portions, and means for securing said top and bottom portions;    b) a sloped split impeller within and in spaced relationship with said housing, said impeller having outwardly extending blades and formed in two parts, and means for securing said two parts together, and    c) a split adapter on which said impeller is mounted, said adapter having an opening for receiving a drive shaft, said impeller housing cooperating to discharge fluid through said discharge outlet opening in response to rotation of said impeller.    
     
     
         2 . The centrifugal pump of  claim 1  wherein said housing has a pair of aligned fluid inlet means.  
     
     
         3 . The centrifugal pump of  claim 1  including a drive shaft extending through a fluid inlet opening and through said adapter in spaced non-contacting relationship with said housing around said drive shaft.  
     
     
         4 . The centrifugal pump of  claim 1  wherein said drive shaft includes a propeller.  
     
     
         5 . The centrifugal pump of  claim 1  wherein said impeller has a slope on both sides of about 30 to 45 degrees.  
     
     
         6 . The centrifugal pump of  claim 1  including a motor associated with said housing and a drive shaft within said housing operatively connected for rotation by said motor, and means for activating said motor.  
     
     
         7 . The centrifugal pump of  claim 6  wherein said pump is immersible.  
     
     
         8 . The centrifugal pump of  claim 1  wherein said adapter comprises two hemispheres having ridges on its ends and said impeller sits between said ridges.  
     
     
         9 . The centrifugal pump of  claim 1  wherein said adapter comprises plastic material.  
     
     
         10 . The centrifugal pump of  claim 1  including a drainage port in the bottom portion of said housing.  
     
     
         11 . The centrifugal pump of  claim 1  including a lining in said housing.  
     
     
         12 . The centrifugal pump of  claim 1  wherein inlet opening on both sides of said impeller create substantially equal pressure on both sides of said impeller.  
     
     
         13 . The centrifugal pump of  claim 1  in combination with a drive shaft and a motor.  
     
     
         14 . A self priming centrifugal pump for use with fluids, gases, and solids comprising a drive shaft, a motor means for driving said drive shaft, a split housing having a split impeller mounting on said shaft in spaced relationship within said housing, inlet means in said housing about the shaft so that there is equal pressure on both sides of the impeller, and outlet means for discharging fluids, gases or solids in response to rotation of said impeller.
