Abstract
A modular fluid end for a multiplex plunger pump, each module machined from a single-piece steel forging with a plunger bore intersected by a linear suction/discharge bore and pumped fluid is discharged straight out through a top of the module into a discharge manifold made up using 1502 frac iron components. A compression clamp applies a crush load to opposed sides of the modules to extend service life.
Claims19
A modular fluid end for a multiplex plunger pump, comprising:
- at least two fluid end modules arranged in a side-by-side relationship, each of the fluid end modules having a cylinder with a plunger bore that receives a plunger, an intake end and a discharge end with a linear suction/discharge bore through the intake end and the discharge end and that intercepts the plunger bore, the discharge end being connected directly to a discharge manifold;
- and
- a compression clamp comprising two compression plates and compression clamp fasteners that interconnect the two compression plates wherein the compression clamp is entirely disposed external to the at least two fluid end modules, the compression clamp applying a crush load to opposite sides of respective outermost ones of the at least two fluid end modules.
A fluid end module for a multiplex plunger pump, comprising:
- at least two cylinders, each cylinder having a plunger bore and a suction/discharge bore that intercepts the plunger bore at right angles and extends straight through an intake end on one side of each cylinder and a discharge end on the other side of each cylinder;
- a mounting plate on an inner end of each cylinder;
- a crush load transfer boss on each cylinder, the respective crush load transfer bosses being aligned with the interception of the plunger bore and the suction/discharge bore;
- and
- a compression clamp comprising two compression plates and compression clamp fasteners that interconnect the two compression plates wherein the compression clamp is entirely disposed external to the at least two cylinders, the compression clamp applying a crush load to opposite sides of respective outermost ones of the at least two cylinders.
