    摘要： A pump including a power end (202) and a fluid end (204). A bore (214) extends through the fluid end (204). A rod (212) is disposed in the bore (214) of the fluid end (204) and extends into the power end (202). The rod (212) includes a reduced diameter portion (222) and the rod (212) is configured to connect the power end (202) and the fluid end (204). The pump also includes a retaining apparatus (216) coupled to the reduced diameter portion (222) of the rod (212). A shoulder (218) is formed between a first inner diameter (226) of the bore (214) and a second inner diameter (228) of the bore (214). The first inner diameter (226) is smaller than an outer diameter of the retaining apparatus (216). A first end (260) of the retaining apparatus (216) is configured to contact the shoulder (218) and a second end (262) of the retaining apparatus (216) is configured to contact a contact surface formed on the rod (212) in order to restrict movement of the rod (212) within the bore (214).

    摘要： A valve stop retainer device (220) that is adapted to interface with a cross-bore fluid communication chamber (262) of a reciprocating pump (250) includes a spring retainer plate (221) and a plurality of retainer lobes (223) extending substantially away from a first side of the spring retainer plate (221). Each of the plurality of retainer lobes (223) includes an upper portion (223u) having an outer surface (223s). A shape of each of the outer surfaces (223s) and a shape of an inside surface (261) of the cross-bore fluid communication chamber (262) interfacing with the valve stop retainer device (220) substantially conform to a shape of at least a portion of a surface of revolution. The valve stop retainer device (220) is adapted to be retained inside of the cross-bore fluid communication chamber (262) by the shape of the inside surface (261).

    摘要： A system for mounting a fluid end (420) of a pump (400) to a power end (410) of the pump (400) includes an upper clamping bar (448) and a clamping assembly (460) that is adapted to removably clamp the fluid end (420) to the upper clamping bar (448). The clamping assembly (460) includes a clamp bar (462) having a first tapered clamping face (462x) that is adapted to contact a correspondingly tapered clamping face (448x) on the upper clamping bar (448) when the fluid end (420) is removably clamped to the upper clamping bar (448).

    摘要： A pump including a power end (202) and a fluid end (204). A bore (214) extends through the fluid end (204). A rod (212) is disposed in the bore (214) of the fluid end (204) and extends into the power end (202). The rod (212) includes a reduced diameter portion (222) and the rod (212) is configured to connect the power end (202) and the fluid end (204). The pump also includes a retaining apparatus (216) coupled to the reduced diameter portion (222) of the rod (212). A shoulder (218) is formed between a first inner diameter (226) of the bore (214) and a second inner diameter (228) of the bore (214). The first inner diameter (226) is smaller than an outer diameter of the retaining apparatus (216). A first end (260) of the retaining apparatus (216) is configured to contact the shoulder (218) and a second end (262) of the retaining apparatus (216) is configured to contact a contact surface formed on the rod (212) in order to restrict movement of the rod (212) within the bore (214).
