ABSTRACT:
A positive displacement pump has a cylinder closed at one end and a plunger projecting from the opposite end reciprocable therein. Rings and packing are inserted at the opposite end to guide the plunger and are designed to provide that the plunger has a material clearance from the cylinder walls. To use a different sized plunger the rings and packing are designed for easy removal at the end of the cylinder and for replacement by rings and plunger corresponding to the new plunger section. A convenient manual linkage is provided for manual operation of the pump with the cylinder upright. A convenient horizontal frame is provided for the pump with a drive means for the pump used with the cylinder in a horizontal position.
