Abstract: A packing assembly to be disposed within a stuffing box defined by a fluid end of a body of a reciprocating plunger pump includes an elastomeric component and a wear component. The elastomeric component has an at least partially tapered inner diameter and an outer diameter and, in use, engages the stuffing box on the outer diameter and is axially compressed within the stuffing box. The wear component sealably engaging the elastomeric component across the at least partially tapered inner diameter and dynamically contacts the plunger to form a dynamic seal.

Abstract: The water misting system includes a stationary member 3, 4 having a flow path therein for transmitting water, the rotary swivel 5 in fluid communication with the stationary member, and one or more conduits 6, 7 in communication with the stationary member and extending radially outward from the swivel. A misting nozzle 8, 9 is provided at an outer end of each respective conduit, and has a central nozzle axis angled with respect to a central axis of a respective conduit for discharging mist while producing a tangential thrust for rotating the one or more conduits and the misting nozzle about the stationary member. According to the method of the invention, angling of the central nozzle axis of each misting nozzle with respect to a central axis of the respective conduit produces the tangential thrust to rotate the conduits and thereby mist a large area.
