PURPOSE: To make a carrier fluid carrying no pulstion flow and excellent in quantitative characteristics feedable as well as to cause air bubbles to be hardly produced there, besides ease of maintenance, by driving two plungers, whose sectional area is in the ratio 2:1 each, for reciprocating motion, while coupling all ranges from a discharge port of one side pump head to a suction port of the other side pump head.
CONSTITUTION: From the point that suction of 12a and discharge of 12b are all over, a connecting rod 10 gets moving to the left at a fixed speed (-v) while a carrier fluid stored in a first pump head is discharged from piping 13 at a fixed flow rate 2g0 but at this time, simultaneously a plunger 11b is as well pulled back to the left side at the fixed speed (-v) so that half of the fluid in the total carrier fluid fed out of the piping 13 is stored inside a cylinder in a second pump head 12b at a fixed flow rate g0 and the rest half of the carrier fluid is fed to a separation column 7 at the fixed flow rate g0 by way of piping 15.
