Description

The major components of the pump models in the 7785 series 

consist of an air-operated motor and a pump tube. The air motor 
connects directly to the double-acting reciprocating pump tube.

are designed to deliver a range of greases (up to NLGI # 3) and 
operate directly from their original drums or bulk containers*.
