Pump device

Abstract

Pump device comprising a pump insert, without a dedicated housing, and a receiving part, wherein the pump insert is inserted in the receiving part, wherein in the receiving part the suction passage for the pump insert is designed for sucking in a fluid, wherein in the suction passage provision is made for an insertion part for optimizing fluid guiding.

1 . A pump device comprising a pump insert, without a dedicated housing, and a receiving part, wherein the pump insert is inserted into the receiving part in a housing which is in fluid communication with a suction passage of the pump insert for sucking in a fluid,
 wherein the receiving part the suction passage is produced without metal cutting, wherein in the suction passage provision is made at least partially for an insertion part for optimizing fluid guiding, which has the shape of a funnel which from an outside diameter, which corresponds to the inside diameter of the suction passage, widens to a diameter of the housing.   
     
     
         2 . The pump device as claimed in  claim 1 ,
 wherein the receiving part forms a receptacle for intake of a fluid.   
     
     
         3 . The pump device as claimed in  claim 1 ,
 wherein the receiving part is a transmission casing.   
     
     
         4 . The pump device as claimed in  claim 1 , wherein the insertion part is produced from plastic. 
     
     
         5 . The pump device as claimed in  claim 1 , wherein the insertion part is produced in a plastic injection molding process. 
     
     
         6 . The pump device as claimed in  claim 1 , wherein the pump device is designed as a vane cell pump or gear pump. 
     
     
         7 . The pump device as claimed in  claim 1 , wherein the pump insert has at least two spaced apart radial seals for sealing against the receiving part.
