Pump valve fittings Commonly used diaphragms are mainly used for diaphragm pumps to meet the requirements of non-corrosive, granular and oily liquids. This product has the characteristics of fatigue resistance, friction resistance, oil resistance, etc. It is one of the commonly used pump valve accessories. Mainly include: plastic diaphragm, butyl diaphragm, PTFE diaphragm, polyether diaphragm and Teflon diaphragm.


Diaphragm sheets of different materials are suitable for different working situations. Under normal circumstances, the diaphragm valve fittings of nitrile rubber are suitable for the transportation of gas, oil and medium weak corrosive liquids. Fluorobutadiene rubber is resistant to various acidic and alkaline liquids. Fluororubber material can meet the requirements of various organic solutions such as acid and alkali, toluene and so on.


In addition, PTFE and F46 pump valve fitting diaphragms can be used to resist strong acids, alkalis and various organic solvents. These different materials can meet the needs of different users, placed in a variety of special occasions, used to pump a medium that can not be pumped by conventional pumps, have achieved satisfactory results.http://www.dmgcastings.com/
