Pump drive

Abstract

1. Pump drive 2.1 Known pump drives, to the extent that they can be separated from their pumping mechanism, must be set onto the pumping mechanism with two hands, because of their weight. Connecting the drive with the pumping mechanism, which is done by way of a flange or a screw connection, is therefore difficult for one person to handle. Therefore the invention is based on the task of creating a pump drive that makes possible simple and, at the same time, effective connection of the pump drive with a container pump. 2.2 This task is accomplished by the pump drive according to the invention, by means of a locking mechanism activated by way of handles, by means of which the user can, at the same time, hold, position, and unlock or lock the drive. 2.3 Operation of container pumps

1 . Pump Drive having a housing ( 1 ), in which a motor ( 11 ) is disposed to drive a pumping mechanism ( 9 ), in such a manner that the drive shaft ( 2 ) of the motor ( 11 ) passes through the housing wall, a driving mechanism ( 8 ) for non-positive-lock coupling onto a pump shaft is assigned to the drive shaft ( 2 ), on the outside wall of the housing, and the housing ( 1 ) has at least one handle ( 4 ) that puts a locking mechanism ( 3 ) into engagement with a holder recess of the pumping mechanism ( 9 ) in a locked position.  
   
   
       2 . Pump drive according to  claim 1 , wherein the housing ( 1 ) has two handles ( 4 ), whereby these handles ( 4 ) are disposed distributed over the circumference of the housing ( 1 ) in such a manner that the pump drive can be operated with two hands.  
   
   
       3 . Pump drive according to  claim 1 , wherein, the handles ( 4 ) have a contract edge ( 13 ) that is in contact with the housing ( 1 ) in the locked state, the contact edge ( 13 ) has a turning end ( 14 ) and a locking end ( 15 ), the turning end ( 14 ) is articulated onto the housing ( 1 ) by way of a pivoting connection, preferably by way of an articulated lever connection, and the locking end ( 15 ) can be connected with the housing ( 1 ).  
   
   
       4 . Pump drive according to  claim 3 , wherein each handle ( 4 ) has a safety locking mechanism ( 6 ) on its locking end ( 15 ) and the housing ( 1 ) has catches ( 10 ) in the region of the contact points of the handles ( 4 ), to produce a releasable connection of the locking end ( 15 ) with the housing ( 1 ).  
   
   
       5 . Pump drive according to  claim 1 , wherein the pump drive, set onto a container pump and/or onto a container in accordance with its intended purpose, is mounted so as not to rotate, at least because of the locking engagement.  
   
   
       6 . Pump drive according to  claim 1 , wherein the motor ( 11 ) has a speed of rotation setter assigned to it, in such a manner that the speed of rotation can be adjusted from outside the housing ( 1 ).  
   
   
       7 . Pump drive according to  claim 6 , wherein the speed of rotation setter can be set by way of a turning handle ( 5 ), which is integrated into the housing ( 1 ) with a positive lock, on the side of the pump drive that lies opposite the driving mechanism ( 8 ), whereby preferably, the turning handle ( 5 ) has handle depressions ( 7 ) distributed over its circumference.  
   
   
       8 . Pump drive according to  claim 1 , wherein a foam insert ( 12 ) surrounds the motor ( 11 ), within the housing ( 1 ), in such a manner that the former is accommodated in the housing ( 1 ) with a positive lock.  
   
   
       9 . Pump drive according to  claim 1 , wherein an extraction tap is integrated into the housing ( 1 ) in such a manner that the tap forms a continuous feed channel with the container pump to be connected and/or the container to be connected.  
   
   
       10 . Pump drive according to  claim 9 , wherein the locking mechanism ( 3 ) forms a sealing connection in its locked state, in the region of the connection between extraction tap and container pump and/or container.  
   
   
       11 . Pump drive according to  claim 8 , wherein an air channel is formed between foam insert ( 12 ) and housing ( 1 ), whereby the air that is drawn in enters into the housing ( 1 ) in the region of an air entry opening, is guided between housing wall and foam insert ( 12 ) to one side of the motor ( 11 ), can be drawn through the motor ( 11 ) using a fan ( 16 ), and the air can be passed out of the housing ( 1 ) through exit openings ( 17 ).
