摘要
A packing assembly for sealing a space between a pump plunger (130) and a pump body of a reciprocating plunger pump with a plunger (130) having a pumping end (180) with an outer perimeter. At least one seal (170) is disposed around the pumping end of the plunger and a securing member (195) having a first end (210) capable of attachment to the pumping end of the plunger. A second end (200) having a flange with an outer perimeter greater than the outer perimeter of the pumping end of the plunger is also provided, such that when the first end of the securing member is attached to the pumping end of the plunger, the second end maintains the at least one seal (170) disposed around the pumping end of the plunger.
