A pump piston without a valve. Also called plunger lift.
Webster 3rd
The pump barrel, or cylinder, in which a solid piston or plunger works.
Also called pole case. Fay
A washer in which water is forced upward and then downward through a
screen by the action of a plunger in an adjoining compartment. Although
these machines are still in use, the term "jig washer" is now applied to
the fixed-screen, air-pulse jig, which is directly descended from the
first Baum washer used in 1892. See also:jig washer; pneumatic jig.

a. Reciprocating pump used for moving water or pulp, in which a solid
piston displaces the fluid. Pryor, 3
b. A displacement-type pump may be of various types, such as: (1) the
triplex pump, a vertical or horizontal, single-acting plunger type for
small heads with three single-acting cylinders in the pump frame driven by
a motor mounted on the outside of the frame and connected to the
crankshaft of the pump through gearing; (2) the quadruplex or quintuplex
pump, a pump having four or five cylinders; and (3) the duplex pump, a
crank-and-flywheel type for high heads, with double-acting plungers.

b. Pertaining to rocks formed by any process at great depth.
Syn:abyssal; deep seated; hypogene. AGI
Deep-seated regional metamorphism at high temperatures and pressures,
often accompanied by strong deformation; batholithic intrusion with

differential fusion or anatexis) is characteristic.
CF:injection metamorphism
Collectively, the major group of ore deposits of magmatic origin that have
been formed under abyssal conditions. Schieferdecker
Igneous rock formed deep within the Earth under the influence of high heat
and pressure, hypogene rocks; distinguished from eruptive rock formed at
the surface. Hess
A series of different igneous rocks that evolved from the same original
magma through various differentiation stages.
a. The obsolete belief that all of the rocks of the Earth solidified from
an original molten mass. CF:neptunism
