A series of simple booster pumps operating as positive displacement pumps driven by either pneumatic or hydraulic power cylinders simply attached to the respective pump chambers which receive piston rods upon each cylinder stroke, controllable as to its length by an adjustable stop-plug thereby displacing fluid from pump chamber at pressures proportional to the ratios of rod diameters versus piston diameter, with or without integral check valves in the inlet or outlet ports of the pump chamber, with a shuttle valve built-in in the inlet port of the design for handling aerated fluids such as grease, eggnog or the like, and a built-in outlet check valve in the same pump chamber, and appropriate seals separating the actuation power cylinder from the pressurization pump chamber by a threaded connection representing the only means for connecting actuator to the pump chamber and providing simple booster pump construction with provisions for capacity change by virtue of interchanging cylinders from one size of a given maximum capacity to another size with completely different boosting and volume control capabilities, all with extreme easiness and simplicity, mandatory in pollution control equipment manufacture, among other vital applications.
