Reciprocating Pumps - Diaphragm, Piston, Plunger
These pumps have a diaphragm, piston or plunger which is
reciprocating back and forth through a fixed stoke length. The
diaphragm pumps use a circular semi-flat membrane that is flexed
from a concave to a convex shape within a sealed chamber. There is
no actual sliding contact of parts in the pumping chamber and
therefore these pumps can handle solids, slurries, fibrous and very
thick liquids quit well. Most diaphragm pumps are air operated, but
electric do exist. Electric models are typically very small with
several individual diaphragms working in series being driven by a
rotating angled cam or a single diaphragm being driven by a
mechanical connection to a solenoid. In this case, they are
typically designed as metering pumps. Piston pumps like the name
implies have a piston, ceramic typically, reciprocating within a
very tight tolerance cylinder. Because of their materials of
construction and mechanical design, they produce extremely high
discharge pressures. By making them with several pistons working
together in a single head a semi-steady flow can be obtained. With
any of these pumps special consideration must be given to the
cyclic pressure or hydraulic pulsation’s which
naturally occur.Typical Positive Displacement Reciprocating pumps
include AODD, single diaphragm, electric diaphragm, metering or
proportioning and piston to name a few.
