  Features 1.Very high safety of operation. Mechanical actuate diaphragm. Changeable eccentric drive 2.Power off seal,no leakage,with security delivery device,simple maintance 3.It can transport high-viscosity mediums, corrosive liquid and dangerous chemical goods. 4.The flow can be controlled via adjusting the length of stroke or the motor frequency. 5.The diaghragm is made from multilayer complex structure to promote the life span, the first layer is Teflon anti-acid diaphragm, the second is EPDM stretch rubber, the third is 3.00 mm thick SUS304 that supporting the iron corn. The fourth is also the EPDM stretch rubber to cover all of the body.   Purpose Widely used in petroleum, chemical industry, electric power, metallurgy, mining, shipbuilding,light industry, agriculture, national defense department and etc.
