Rubber

For example, rubber diaphragms are molded from natural rubber, with artificial additives added to the rubber to improve the diaphragm's chemical resistance and flexibility.performance.

Neoprene(Neoprene)……Applied to inexpensive ordinary diaphragms for non-corrosive liquids.

Nitrile rubber (Buna-U)……Inexpensive diaphragm for petroleum/oil-based liquids.

EPDM rubber(EPDM)……Good flex life under extremely low temperature conditions.

Fluorinated rubber(Viton)……Good flex life under extremely high temperature conditions, used to transport aromatic or chlorinated hydrocarbons and acidic liquids.

PolytetrafluoroethyleneF46 (Teflon Teflon)
Teflon is considered the most chemically stable synthetic material. Yangtze River Pump Industry Co., Ltd. manufactures patented Teflon diaphragms with reinforcing ribs to control the bending shape of the diaphragm and extend its life. The innovation of using this Teflon diaphragm improves cost-effectiveness, while greatly expanding the application range of diaphragm pumps. Teflon is not an elastic material and has no elasticity, so there is a support diaphragm to provide support and extend life.
