Abstract: A reciprocating pump includes a housing, a rod, and a bellows. The housing surrounds a bellows chamber and a displacement chamber. A portion of the rod extends through the opening in the endcap and into the bellows chamber of the housing. A cross-section of the rod includes a lobed shape. The bellows is connected to the housing and to the rod such that the bellows surrounds a portion of the rod.

Abstract: A lubrication system comprises a lubricant reservoir, a motorized pump, a follower plate, a stationary rod, a movable sleeve, and a flexible connection. The motorized pump is disposed to pump fluid from the lubricant reservoir to lubricant work lines. The follower plate is situated within the lubricant reservoir. The stationary rod has a colored indicator portion. The movable sleeve disposed concentrically about the stationary rod. The flexible connection extends between the follower plate and the stationary colored rod, such that the flexible connection pulls the movable sleeve away from the stationary rod to reveal the colored indicator portion as the follower plate drops towards a bottom of the lubricant reservoir.

Abstract: A check valve includes a ball and a seat. The seat includes a body and a hole extending through the body. The hole is smaller in diameter than the ball. The body of the seat is formed from ultra-high-molecular-weight polyethylene. The ultra-high-molecular-weight polyethylene of the seat has an ASTM D648 heat deflection temperature of 46.7° C. at 1.8 MPa.

Abstract: A series progressive divider valve comprises a valve body and pistons. A fluid inlet extends into the valve body. Stations are disposed in the valve body and extend from a first end to a second end; each station comprises piston stations extending through the valve body and a bypass station fluidly isolating the first end from the second end. The piston stations comprise a piston bore and a piston. The bypass stations comprise first and second fluid passages extending from the first and second ends to positions inside the valve body. Outlet bores extend into the valve body, and each comprises first and second sets of outlet bores. Porting forms passageways connecting the stations to each other and with the outlet bores such that when high pressure fluid is applied to the inlet the pistons reciprocates from the first end to the second end in sequence.
