ることを特徴とする往復動ポンプ。In the cylinder part that supports the plunger that performs the main pump operation, a flush pipe is installed behind the maximum retracted position of the plunger where it comes into contact with the liquid handled by the pump, and a flushing area is formed on the side of the pump chamber in front of this flush pipe, and The reciprocating pump is configured such that the flush liquid cleans the surface of the plunger by providing a backing on the drive source side and connecting the reciprocating pump for flush liquid supply to the flush pipe. The rotational phase difference of the pump is set to 180', so that the ratio of the amount of flush liquid mixed in to the flow rate of the main pump handling liquid (dilution ratio) is always constant regardless of the pump rotation speed, and the amount of flush liquid supplied is reduced as the plunger retracts. A reciprocating pump characterized in that the main pump and the reciprocating pump for flush liquid supply are connected to a common drive source so that the speed increases or decreases in proportion to the magnitude of the speed.
