Abstract
A stuffing box assembly for a fluid end of a hydraulic fluid pump includes a first stuffing box member having a first plunger bore configured to receive a plunger of the hydraulic fluid pump and a plurality of seals. The first stuffing box member further comprises a first bore spaced apart from the plunger bore. A second stuffing box member has a threaded stuffing nut bore configured to receive a stuffing nut of the hydraulic fluid pump. The second stuffing box member further comprises a second bore spaced apart from the stuffing nut bore. A fastener is configured to extend through the first and second bores to secure the first stuffing box member to the second stuffing box member.
Claims21
A stuffing box assembly for a fluid end of a hydraulic fluid pump, the stuffing box assembly comprising:
- a first stuffing box member having a plunger bore configured to receive a plunger of the hydraulic fluid pump and a plurality of seals, the first stuffing box member further comprising a first bore spaced apart from the plunger bore and a third bore that is spaced apart from the first bore;
- a second stuffing box member having a stuffing nut bore configured to receive a stuffing nut of the hydraulic fluid pump, the second stuffing box member further comprising a second bore spaced apart from the stuffing nut bore;
- a first fastener configured to extend through the first bore and the second bore to secure the first stuffing box member to the second stuffing box member;
- and
- a second fastener configured to extend through the third bore and into the fluid end to secure the first stuffing box member to the fluid end, wherein the second stuffing box member extends over the third bore to preclude access to the third bore when the first stuffing box member is secured to the second stuffing box member.
