Abstract
A packing assembly for a pump fluid end comprising: a packing screw; a packing carrier; and a packing, wherein the packing screw, the packing carrier, and the packing are each cylindrical with a width measured along a central axis thereof that is less than a minimum spacing distance of a pump comprising the pump fluid end and a pump power end, wherein the pump fluid end comprises a reciprocating element bore in which a reciprocating element can be reciprocated via the pump power end via connection of the reciprocating element to a reciprocating element adapter coupled with a pushrod and crankshaft of the pump power end, wherein the minimum spacing distance is an axial distance measured along the central axis between a back of the pump fluid end and a front end of the reciprocating element adapter when the crankshaft of the pump power end is at top dead center.
