Double Diaphragm Pump

In hydraulic pump the process liquid is isolated from plunger by hydraulic oil and a diaphragm. Normally Teflon is used as a diaphragm material due to its flexibility and corrosion resistivity. domestic and industrial diaphragm type dosing pumps, hydraulic diaphragm pumps, shaped diaphragm pumps and air-operated double diaphragm pumps.When the liquid being is highly corrosive, the backup diaphragm will keep the liquid out of pump body in the primary diaphragm, allowing the diaphragm to be replaced before the pump is damaged.
