Dencil pumps & systems manufactures fix stroke duplex hydraulic operated diaphragm pumps for handling corrosive liquids and those containing abrasive solid suspensions. These diaphragm pumps are available in two sections separated by a diaphragm where in one section; a piston or plunger operates in a cylinder in which non-corrosive fluid is displaced. The pumps are equipped with flexible diaphragm to transmit the movement of the fluid to the liquid to be pumped. The valves of these diaphragm pumps are the only moving parts that come in contact with the liquid and these can be specially designed to handle the material. In some cases diaphragm movement produced by direct mechanical action or the diaphragm may be actuated. Ptfe diaphragm of the diaphragm pumps hermetically separates wetted area from the hydraulic chamber that balances the stroke during the discharge. The diaphragm operation is aided by the mechanical coupling during the section stroke. This combined principle of these diaphragm pumps offers an extraordinary suction lift capability.
