| Diaphragm pumps are common industrial pumps
that normally use positive displacement to move liquids. These
devices typically include a single diaphragm and chamber, as
well as suction and discharge check valves to prevent backflow.
Pistons are either coupled to the diaphragm, or used to force
hydraulic oil to drive the diaphragm. Housing materials might
include aluminum, brass or bronze, cast iron, plastic and stainless
steel. Rugged diaphragm pump housings can withstand high temperatures
and may be exposed to various grades of water, oils, and other
solvents. |
