         6 . The lubricant pump according to  claim 2 , characterized by the fact that the first pump unit comprises a connecting region for connecting the other second pump unit such that the second pump unit does not extend beyond the connecting region in at least one direction, and by the fact that the input shaft is arranged outside of the connecting region in the first pump unit. 
     
     
         7 . The lubricant pump according to  claim 2 , characterized by the fact that the first pump element of the first pump unit is arranged on a side of the first pump unit that faces away from the second pump unit. 
     
     
         8 . The lubricant pump according to  claim 2 , characterized by the fact that the means for driving one of the pump elements comprises a swash plate. 
     
     
         9 . The lubricant pump according to  claim 2 , characterized by the fact that the means for driving one of the pump elements comprises a cam plate. 
     
     
         10 . The lubricant pump according to  claim 2 , characterized by the fact that the first pump unit comprises another input shaft, to which is assigned a transmission that can be coupled to the means for driving the pump elements. 
     
     
         11 . A machine comprising at least one lubricating point to be supplied with oil, at least one lubricating point to be supplied with grease, and a lubricant pump according to  claim 2  for respectively supplying the lubricating points with oil and grease. 
     
     
         12 . The machine of  claim 11 , wherein the machine is a baling press. 
     
     
         13 . The lubricant pump according to  claim 1 , characterized by the fact that each of the first and second pump units comprises a separate housing, and wherein the housings of the pump units can be connected into one unit in a separable fashion. 
     
     
         14 . The lubricant pump according to  claim 1 , characterized by the fact that the first and second pump units comprise mutually assigned connecting means.
