Abstract

A plunger clamp is disclosed that includes a body comprising a first end, a second end, and a clamp connector disposed between the first and second ends, wherein the clamp connector comprises a threaded portion that interfaces with one or both of the first and second ends facilitating relative rotation with, and separation from, the first and second ends and the clamp connector.

Claims (48)

1. A plunger clamp, comprising:

a body comprising a first end, a second end, and a clamp connector disposed between the first and second ends, wherein the clamp connector comprises a threaded portion that interfaces with one or both of the first and second ends facilitating relative rotation with, and separation from, the first and second ends and the clamp connector, wherein the clamp connector comprises a circular retainer member that is disposed in a groove formed in the second end to couple the clamp connector and the second end together.

2. The plunger clamp of claim 1 , wherein the threaded portion of the clamp connector comprises female threads that engage male threads formed on the first end to couple the clamp connector and the first end together.

3. The plunger clamp of claim 2 , wherein the male threads are broken by recessed portions.

4. The plunger clamp of claim 1 , wherein the first and second ends include recessed portions corresponding to positions of fastener holes formed therethrough.

5. The plunger clamp of claim 1 , wherein the first end or the second end includes a plurality of blind holes formed on a perimeter thereof that extend in a direction orthogonal to a longitudinal axis of the body.

6. A plunger clamp, comprising:

a body comprising a first end, a second end, and a clamp connector disposed between the first and second ends, wherein:

the clamp connector comprises a threaded portion that interfaces with one or both of the first and second ends;

the clamp connector includes a plurality tool interfaces formed on a perimeter thereof that extend in a direction orthogonal to a longitudinal axis of the body; and

at least one of the first and second ends include recessed portions corresponding to positions of fastener holes formed therethrough.

7. The plunger clamp of claim 6 , wherein the clamp connector comprises a circular retainer member that is disposed in a groove formed in the second end to couple the clamp connector and the second end together.

8. The plunger clamp of claim 6 , wherein the clamp connector comprises a retainer.

9. The plunger clamp of claim 6 , wherein the threaded portion of the clamp connector comprises female threads that engage male threads formed on the first end to couple the clamp connector and the first end together.

10. The plunger clamp of claim 9 , wherein the male threads are broken by recessed portions.

11. The plunger clamp of claim 6 , wherein the clamp connector comprises left handed threads and right handed threads.

12. The plunger clamp of claim 6 , wherein the clamp connector comprises a split-ring retainer.

13. A fluid end, comprising:

a body having a plurality of bores formed therein that intersect at a junction;

a plunger disposed in one of the plurality of bores; and

a plunger clamp coupled to the plunger, the plunger clamp comprising:

a first end, a second end, and a clamp connector disposed between the first and second ends, wherein:

the clamp connector comprises a threaded portion that interfaces with one or both of the first and second ends; and

one or both of the first end and the second end, and the clamp connector, includes a plurality tool interfaces formed on a perimeter thereof that extend radially inward in a direction orthogonal to a longitudinal axis of the plunger clamp, wherein at least one of the first and second ends include recessed portions corresponding to positions of fastener holes formed therethrough.

14. The fluid end of claim 13 , wherein the clamp connector comprises a circular retainer member that is disposed in a groove formed in the second end to couple the clamp connector and the second end together.

15. The fluid end of claim 13 , wherein the clamp connector comprises a retainer.

16. The fluid end of claim 13 , wherein the threaded portion of the clamp connector comprises female threads that engage male threads formed on the first end to couple the clamp connector and the first end together.

17. The fluid end of claim 16 , wherein the male threads are broken by recessed portions.

18. The fluid end of claim 13 , wherein the clamp connector comprises left handed threads and right handed threads.

19. The fluid end of claim 13 , wherein the clamp connector comprises a split-ring retainer.

20. A plunger clamp, comprising:

a body comprising a first end, a second end, and a clamp connector disposed between the first and second ends, wherein the clamp connector comprises a threaded portion that interfaces with one or both of the first and second ends facilitating relative rotation with, and separation from, the first and second ends and the clamp connector, wherein the threaded portion of the clamp connector comprises female threads that engage male threads formed on the first end to couple the clamp connector and the first end together, and wherein the male threads are broken by recessed portions.

21. A plunger clamp, comprising:

a body comprising a first end, a second end, and a clamp connector disposed between the first and second ends, wherein the clamp connector comprises a threaded portion that interfaces with one or both of the first and second ends facilitating relative rotation with, and separation from, the first and second ends and the clamp connector, and wherein at least one of the first and second ends include recessed portions corresponding to positions of fastener holes formed therethrough.

22. A fluid end, comprising:

a body having a plurality of bores formed therein that intersect at a junction;

a plunger disposed in one of the plurality of bores; and

a plunger clamp coupled to the plunger, the plunger clamp comprising:

a first end, a second end, and a clamp connector disposed between the first and second ends, wherein:

the clamp connector comprises a threaded portion that interfaces with one or both of the first and second ends; and

one or both of the first end and the second end, and the clamp connector, includes a plurality tool interfaces formed on a perimeter thereof that extend radially inward in a direction orthogonal to a longitudinal axis of the plunger clamp, wherein the clamp connector comprises a circular retainer member that is disposed in a groove formed in the second end to couple the clamp connector and the second end together.

23. A fluid end, comprising:

a body having a plurality of bores formed therein that intersect at a junction;

a plunger disposed in one of the plurality of bores; and

a plunger clamp coupled to the plunger, the plunger clamp comprising:

a first end, a second end, and a clamp connector disposed between the first and second ends, wherein:

the clamp connector comprises a threaded portion that interfaces with one or both of the first and second ends; and

one or both of the first end and the second end, and the clamp connector, includes a plurality tool interfaces formed on a perimeter thereof that extend radially inward in a direction orthogonal to a longitudinal axis of the plunger clamp, wherein the male threads are broken by recessed portions.
