Abstract

A plunger clamp is disclosed that includes a body comprising a first end and a second end, wherein the body comprises a threaded portion that facilitates coupling and decoupling of the first and second ends, and 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.

Claims (22)

1. A plunger clamp, comprising:

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

2. The plunger clamp of claim 1 , wherein the second end includes a central through hole.

3. The plunger clamp of claim 2 , wherein the central through hole is threaded.

4. The plunger clamp of claim 2 , wherein the center retainer includes a retainer plate having a central opening formed therein.

5. The plunger clamp of claim 1 , wherein the threaded portion of the clamp connector comprises female threads.

6. The plunger clamp of claim 1 , wherein the threaded portion of the center retainer comprises a fastener.

7. The plunger clamp of claim 1 , wherein both of the first end and the clamp connector includes a plurality of blind holes formed on a respective perimeter thereof.

8. A plunger clamp, comprising:

a body comprising a first end and a second end, wherein the body comprises a threaded portion that facilitates coupling and decoupling of the first and second ends, and wherein at least one of the first end and 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, wherein at least one of the first end or the second end includes a threaded central through hole.

9. The plunger clamp of claim 8 , wherein the body includes a retainer plate having a central opening formed therein.

10. The plunger clamp of claim 8 , further comprising a collar that couples between the first end and the second end.

11. The plunger clamp of claim 8 , wherein one or both of the first end and the second end includes a central through hole.

12. A fluid end, comprising:

a fluid 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 body comprising a first end and a second end, wherein the body comprises a threaded portion that facilitates coupling and decoupling of the first and second ends, and 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, wherein one of the first end or the second end includes a threaded central through hole.

13. The fluid end of claim 12 , wherein the body includes a retainer plate having a central opening formed therein.

14. The fluid end of claim 12 , further comprising a collar that couples between the first end and the second end.

15. The fluid end of claim 12 , wherein both of the first end and the second end includes the threaded central through hole.

16. The fluid end of claim 12 , wherein both of the first end and the second end includes the plurality of blind holes formed on a respective perimeter thereof.
