A fluid end comprising a plurality of fluid end sections positioned in a side-by-side relationship. Each fluid end section is releasably attached to a connect plate. Each connect plate is attached to a power source using a plurality of stay rods. Each fluid end section comprises a housing in fluid communication with a pair of intake manifolds and a discharge conduit. A fluid routing plug is installed within each housing and is configured to route fluid throughout the housing. A plunger is installed within stuffing box attached to each housing. A number of features, including the location of seals within bore walls and carbide inserts within valve guides, aid in reducing or transferring wear.

A lubricator package for intermittently delivering a lubricant to lubrication points on packing on a high-pressure reciprocating pump, a frac pump is described. A preferred package includes a large (e.g., 10 gallon) capacity reservoir; a three or five outlet pump; a common manifold receiving oil from the large capacity reservoir and supplying oil or grease to the pumps; a mounting stand supporting the large capacity reservoir and the five outlet pump; and an optional a control package providing low level monitoring of lubricant flow and controlling the pump providing a pump stroke counter or timer.

A submersible pump assembly includes a pump, a motor, and a seal section connected between. A shaft passage in the seal section has an outboard end that is open to the pump intake and an inboard end that is in fluid communication with motor lubricant in the motor. A drive shaft extends axially within the shaft passage. An outboard bearing at the outboard end of the shaft passage receives the shaft to provide radial support. An inboard bearing at the inboard end of the shaft passage receives the shaft to provide radial support. A shaft seal in the shaft passage receives and seals around the shaft. The shaft seal is located between the outboard bearing and the inboard bearing and seals motor lubricant in the shaft passage from well fluid in the shaft passage.
