Abstract
An objective is to provide a reciprocating pump kept from lowering its performances, while restraining the cost from increasing. Collarsmade of a material more excellent in resistance to corrosion than a manifoldare interposed between the manifoldand sealing membersfor liquid-tightly sealing the manifold, so as to prevent the parts in contact with the sealing membersfrom being corroded by a liquid for use, and fully exhibit sealing functions, thereby preventing leakage from occurring in a pump chamberand the pressure oscillation from being increased by the leakage, while the collarsmade of the material excellent in resistance to leakage are used only in the parts in contact with the sealing members
