n: a method of artificial lift in which a subsurface pump located at or near the bottom of the well and connected to a string of sucker rods is used to lift the well fluid to the surface. The weight of the rod string and fluid is counterbalanced by weights attached to a reciprocating beam or to the crank member of a beam pumping unit or by air pressure in a cylinder attached to the beam.

n: an undesirable whipping motion in the sucker rod string that occurs when the string is not properly attached to the sucker rod pump or when the pump is operated at a resonant speed.

n: a steel chamber with an air-charged rubber bladder (or diaphragm) inside that is mounted on a mud pumps intake (suction) line. It absorbs the impact that occurs when the smooth flow of fluid in the suction line coming out of the suction tank meets the intermittent flow caused by fast moving pump pistons.

n: in pipe laying, a type of trenching machine used on river crossings when the channel cannot be diverted or when the volume of material to be removed is large. A suction pump rapidly forces large amounts of soil into a discharge pipe for deposit on the adjacent bank. A cutterhead can also be used on a suction dredge.

n: the line that carries a product out of a tank to the suction side of the pumps. Also called the loading line. suction pit n: also called a suction tank, sump pit, or mud suction pit. See suction tank. suction pressure n: the pressure of a gas or fluid entering the suction valve of a compressor.

n: The pipeline between attachment flange at the induction port of pump and suction pit.

n: A mud tank, usually made of steel, connected to the intake of the main rig pumping system. The connection is commonly formed with a centrifugal pump charging the main rig pumps to increase efficiency. Since it is the last tank in the surface mud system, t

a steel tank containing mud, where the input line to the mud pump originates.

n: The process that liquid be sucked in piston bore.
