A system comprising an objective apparatus and a reciprocation pump, the reciprocation pump comprising: a supply liquid-side pumping chamber configured to supply a liquid from a source to the objective apparatus; a waste liquid-side pumping chamber configured to discharge a waste liquid discharged from the objective apparatus to the outside; a reciprocation means being able to reciprocate between the supply liquid-side pumping chamber and the waste liquid-side pumping chamber, the reciprocating motion of the reciprocation means performing suction and discharge of the liquid to and from the supply liquid-side pumping chamber as well as suction and discharge of the waste liquid to and from the waste liquid-side pumping chamber; and a driving source for driving the reciprocation means; the reciprocation pump adapted to supply the liquid from the source to the objective apparatus with the supply liquid-side pumping chamber and to discharge the waste liquid from the objective apparatus with the waste liquid-side pumping chamber to the outside; the reciprocation pump further comprises a supply liquid-side sub-pumping chamber (P1a) for containing and sending out liquid adapted to be communicated with the supply liquid-side pumping chamber and interlocked with the reciprocation means to vary its volume reversely to that of the volume variation of the supply liquid-side pumping chamber; and a waste liquid-side sub-pumping chamber (P2a) for containing and sending out liquid adapted to be communicated with the waste liquid-side pumping chamber and interlocked with the reciprocation means to vary its volume reversely to that of the volume variation of the waste liquid-side pumping chamber; and that the reciprocating motion of the reciprocation means enables the liquid to be supplied to the objective apparatus through the supply liquid-side pumping chamber and the supply liquid-side sub-pumping chamber (P1a) as well as enables the waste liquid from the objective apparatus to be discharged to the outside through the waste liquid-side pumping chamber and the waste liquid-side sub-pumping chamber (P2a); wherein the supply liquid-side pumping chamber comprises a supply liquid-side inlet port and a supply liquid-side outlet port and the supply liquid-side sub-pumping chamber (P1a) comprises connection ports (1a and 1b), and the waste liquid-side pumping chamber comprises a waste liquid-side inlet port and a waste liquid-side outlet port and the waste liquid-side sub-pumping chamber (P2a) comprises connection ports (1c and 1d). a supply liquid-side pumping chamber configured to supply a liquid from a source to the objective apparatus;
