Abstract
A front-discharge fluid end for a reciprocating pump. The fluid end is distinguished by an outlet valve which is positioned substantially coaxially with the pump plunger and generally facing a longitudinally outer end thereof. The outlet valve is held in place by a valve retainer which includes an outlet port and is connectable to an outlet line. For retrofitting prior pump cylinders, a plug assembly is disclosed for plugging the original outlet valve pocket.
Claims17
A pump fluid end for a plunger pump used for pumping two-phase slurries, said pump fluid end comprising:
- housing means for forming a cylinder having a plunger bore therein and defining an outlet valve pocket at an end of said cylinder, said outlet valve pocket having an annular shoulder therein, said housing means also defining an inlet valve pocket;
- plunger means for reciprocating within said cylinder;
- inlet valve means disposed in said inlet valve pocket for allowing a portion of the slurry to enter said cylinder;
- outlet valve means disposed in said outlet valve pocket and generally facing an end of said plunger means for allowing said portion of said slurry to be discharged from said cylinder in response to movement of said plunger means, said outlet valve means comprising:
- a seat carrier disposed in said outlet valve pocket and having a portion adjacent to said shoulder in said outlet valve pocket, said seat carrier defining a central opening therethrough and having a seat carrier shoulder therein;
- and
- an outlet valve assembly disposed in said central opening of said seat carrier adjacent to said seat carrier shoulder;
- and
- retainer means for engaging said seat carrier and clamping said seat carrier toward said shoulder in said outlet valve pocket and for engaging said outlet valve assembly and clamping said outlet valve assembly toward said seat carrier shoulder.
A pump fluid end for a plunger pump used for pumping two-phase slurries, said pump fluid end comprising:
- housing means for forming a cylinder having a plunger bore therein and defining an outlet valve pocket at an end of said cylinder, said outlet valve pocket having an annular shoulder therein, said housing means also defining an inlet valve pocket;
- plunger means for reciprocating within said cylinder;
- inlet valve means disposed in said inlet valve pocket for allowing a portion of the slurry to enter said cylinder;
- outlet valve means disposed in said outlet valve pocket and generally facing an end of said plunger means for allowing said portion of said slurry to be discharged from said cylinder in response to movement of said plunger means, said outlet valve means comprising:
- a seat carrier disposed in said outlet valve pocket and having a portion adjacent to said shoulder in said outlet valve pocket, said seat carrier defining a central opening therethrough and having a seat carrier shoulder therein;
- and
- an outlet valve assembly disposed in said central opening of said seat carrier adjacent to said seat carrier shoulder;
- retainer means for engaging said seat carrier and clamping said seat carrier toward said shoulder in said outlet valve pocket and for engaging said outlet valve assembly and clamping said outlet valve assembly toward said seat carrier shoulder;
- and
- sealing means for sealing between said seat carrier and said outlet valve assembly pocket and sealing between said outlet valve assembly and said seat carrier.
A pump fluid end for a plunger pump used for pumping two-phase slurries, said pump fluid end comprising:
- housing means for forming a cylinder having a plunger bore therein and defining an outlet valve pocket at an end of said cylinder and also defining an inlet valve pocket, said housing means further defining an original outlet valve pocket transverse to said plunger bore;
- plunger means for reciprocating within said cylinder;
- inlet valve means disposed in said inlet valve pocket for allowing a portion of the slurry to enter said cylinder;
- outlet valve means disposed in the first mentioned outlet valve pocket and generally facing an end of said plunger means for allowing said portion of said slurry to be discharged from said cylinder in response to movement of said plunger means;
- and
- plug means for closing said original outlet valve pocket.
