<p>PROBLEM TO BE SOLVED: To provide a pump having an original performance in the case where re-seal is performed by arranging a torque clip between a packing nut and a packing stack, and forming the torque clip of a material having a spring performance. SOLUTION: A reciprocating piston pump 10 is provided with a piston rod 12, a cylinder 14, a packing stack, and a packing nut, namely, a throat nut 18 for push-pressing the packing stack in a cylinder. The reciprocating piston pump 10 is provided with a torque clip, namely, a holding clip 16 which is arranged between the packing stack and the throat nut 18. The holding clip 16 is formed of piano wire. The using piano wire has an extremely high size telerance (±0.001 inches, namely±0.025 mm) and has a spring performance.</p> |
