Devices {pump, machine}| can receive fluid from one opening, take fluid part, and force fluid out another opening.
types
Pumps {piston pump} can use pistons in cylinders to suck fluid in as they go down, while keeping outlet check valve closed by pressure, and then force fluid out as they go up, while keeping inlet check valve closed by pressure.
Piston pumps {axial piston pump} can use a circle of pistons. Rotating wedges {wobble plate} can press and release pistons as they turn.
Pumps {gear pump} can have two gears, one rotating clockwise and one counterclockwise, which squeeze fluid between teeth and housing and push fluid out one side.
Pumps {vane pump} can have rotors with spring-loaded sliding vanes. Vanes sweep fluid around housing from inlet to outlet.
priming
Fluid fills pumps to start them working {pump priming, fluid}.
