RW series air-operated diaphragm pump of our company is a latest
model of fluid transportation equipment, which is currently one of
the most innovative pumps in china. Using compressed air as the
power source, it can pump various fluids drastically, whether
corrosive, volatile, flammable, poisonous liquid or fluids with
particles and high viscosity.
Our diaphragm pumps have totally six specifications. The sizes for
import/export are 1/4", 1/2", 3/4", 1", 1.5", 2", 3" and 4". The
components which contact with the fluids are usually made of
aluminum alloy, nodular cast iron, polypropylene, stainless steel.
Depend on the varied applications, and the materials of diaphragm
can be styrene rubber, neoprene, polythene, polyether rubber,
fluorine rubber, Teflon and PVDF, so that it can meet the
requirements of different fluid mediums.
