Abstract
A sealing assembly for a pump includes a header ring having a tapered radially outer surface and a sloped radially inner surface. The assembly also includes a first seal configured to couple to the header ring, the first seal having a groove that receives a bead extending from the header ring. The assembly further includes a second seal axially aligned with the first seal.
Claims24
A sealing assembly for a pump, comprising:
- a header ring having a tapered radially outer surface and a sloped radially inner surface, the sloped radially inner surface extending from a planar bottom surface to a second sloped surface, the second sloped surface extending toward the tapered radially outer surface to a bead;
- a first seal configured to couple to the header ring, the first seal having a groove that receives the bead extending from the header ring;
- and
- a second seal axially aligned with the first seal.
1 more element
A pumping system, comprising:
- a housing;
- a plunger configured to reciprocate along an axis of the housing;
- and
- a packing assembly positioned between at least a portion of the housing and the plunger, the packing assembly comprising:
- a header ring having an outer surface bearing against the housing and an inner surface bearing against the plunger, the header ring having a thickness such that the plunger compresses the header ring against the housing, wherein the outer surface includes tapered portion and the inner surface includes sloped entry radius at an axially bottom portion, the sloped entry radius having a curvature that begins at the bottom portion;
- and
- a seal positioned axially higher than and coupled to the header ring, the seal having a groove configured to receive a bead of the header ring, the bead extending axially away from the bottom portion, wherein the seal includes a radially extending sealing feature along a length of the seal.
4 more elements
A packing stack, comprising:
- a header ring extending axially from a bottom to a top, the top having a bead, the header ring having an inner surface with a curved profile extending from a first sloped top entry to the bottom, a bottom thickness being less than a midpoint thickness, and an outer surface with a tapered profile extending from a second sloped top entry to the bottom, the tapered profile arranged at an angle such that a top thickness is less than the bottom thickness;
- and
- a seal extending axially from a bottom end to a top end, at least a portion of the bottom end overlapping the top of the header ring, the seal having a groove that receives the bead, an inner seal surface, and an outer seal surface, the seal being positioned axially aligned with the header ring.
