Abstract
An air-operated reciprocating pump is designed for use with a wide variety of materials having widely varying viscosities. The pump has a stroke which is adjustable so that the piston can operate either entirely within the cylinder or can extend out the bottom end of the cylinder at the end of the stroke for materials having an extremely high viscosity. The stroke adjustment is easily accessible in the area between the pump and the air motor.
