Abstract: An intermittent flushing plunger packing assembly is described herein. The packing assembly includes a plurality of annular seals disposed about the plunger configured to reciprocate along a linear axis within the fluid bore of the pump, and an annular packing nut disposed circumferentially about the plunger and configured to retain the plurality of annular seals and adjust a combined height of the plurality of annular seals. A selected one of the plurality of annular seals proximate to the fluid cylinder of the pump has a flushing fluid chamber in fluid communication with a flushing fluid port coupled to a first one-way check valve allowing a pressurized flushing fluid to be introduced and retained within the flushing fluid chamber and creating a fluid barrier to prevent frac fluid in the fluid cylinder from bypassing the annular seals.

Abstract: A linear pump includes a centrally-disposed drive system and a plunger having a center portion coupled to the drive system, and first and second fluid ends disposed at the first and second ends of the plunger. The pump further includes first and second packing seals each being disposed about the plunger to isolate fluids within the respective first and second fluid ends. First and second adapters are disposed at an interface between the drive system and respective first and second fluid ends, each adapter incorporating an angled deflector configured to deflect and redirect high-pressure fluids escaping past the respective packing seal toward the drive system.
