A high pressure fluid system including enhanced safety, maintenance and servicing features. The system can include a CAM assembly module, having a valve seat assembly, seal cartridge assembly and inlet manifold, that is easily installed in and removed from a frame and/discharge manifold as a single unit. A discharge manifold can isolate different pressure rated passageways of the system, and multiple rupture discs associated with the same. A discharge manifold end plate can be included to provide ease of repair of discharge outlets and to establish a plumbing system for the rupture discs. A quick coupler can facilitate connection between a plunger of the seal cartridge assembly and a cross head stub connected to a power frame. A lubrication valve assembly can provide and meter lubrication from a high pressure inlet source to a plunger and packing of the seal cartridge assembly. |

1. A high pressure fluid end system comprising:
a fluid end system frame including a front portion, a rear portion, a top portion and a bottom portion, the top portion defining a loading opening, the rear portion including a frame retainer and defining a retainer opening; a discharge manifold fixedly joined with the fluid end system frame front portion; a cartridge assembly module, including a valve seat assembly having a discharge valve and a seal cartridge assembly having a plunger adapted for reciprocal movement therein, the valve seat assembly and seal cartridge assembly fixedly secured to one another to form a single, one-piece unit, the cartridge assembly module mounted in the loading opening and projecting at least partially through the retainer opening, the cartridge assembly module being removable from the loading opening and the retainer opening with the valve seat assembly and seal cartridge assembly maintained as the single one-piece unit during the removal; and a retainer element joined with the frame retainer, the retainer element adjustable to force the cartridge assembly module into engagement with at least one of the front portion and the discharge manifold to establish fluid communication between the discharge valve and the discharge manifold, wherein the discharge manifold remains fixedly joined with the fluid end system frame front portion in a single orientation, even as the cartridge assembly module is removed from the loading opening. |
