ABSTRACT:
A pumping system includes a pump having a plurality of cylinders, a suction manifold and a discharge manifold. Each cylinder includes a piston connected to a pump shaft. The system also includes apparatus for rotating the pump shaft so as to move the pistons. A fluid enters the pump by way of the suction manifold, is compressed in the pump by the pistons and the compressed fluid leaves the pump by way of the discharge manifold. Equipment connected to the discharge manifold affects the discharging of the compressed fluid in accordance with the number of cylinders and the rotational frquency of the pump shaft.
