Pneumatic diaphragm pump ability how high temperature

diaphragm pump ability how high temperature, pneumatic diaphragm pump ability how high temperature

many users don't realize how high temperature, the diaphragm pump can either electric or pneumatic diaphragm pump diaphragm pump diaphragm pump products it is inseparable from the diaphragm attachments, diaphragm material mainly fluorine rubber, rubber road, polyether rubber, epdm rubber, ptfe, if does not consider the temperature resistance of the diaphragm pneumatic diaphragm pump adopt stainless steel material temperature ability to 600 degrees, but the diaphragm pump must use the diaphragm, so the diaphragm pump ability depends on how high temperature of diaphragm was affected by temperature, below to share it with all sorts of diaphragm pump and diaphragm pump body material heat resistance of different materials for your reference to choose the appropriate diaphragm water pump products:

if the pump body material polypropylene ( PP) Material, made of PP material pneumatic diaphragm pump can moderate corrosion resistance, good chemical resistance, low cost good commonality, polypropylene material mainly particularly adapted to the common acid and alkali liquid, made of polypropylene plastic pneumatic diaphragm pump the highest temperature only ability to 65 degrees, more than the value of polypropylene plastic deformation. body using polyvinylidene fluoride ( PVDF) Material, this series of pneumatic diaphragm pump belongs to the fluorine plastic pneumatic diaphragm pump, also known as corrosion resistant products, pneumatic diaphragm pump diaphragm liquid contact piece adopts polytetrafluoroethylene material, produced by using PVDF material of pneumatic diaphragm pumps are mainly adapted to strong corrosive, the acid and alkali, main transmission multiple chemical liquid containing solvent, resistance to corrosive effect is very good. This series of fluorine plastic pneumatic diaphragm pump the high heat resistance in 93. Less than 3 degrees. Polyformaldehyde pump body material also has a good solvent resistance and wear resistance, low friction resistance, moisture absorption and low, the highest temperature this kind of pump body in 65. Less than 5 degrees. Ptfe ( PTFE） Diaphragm corrosion resistant performance is very good, with the exception of molten metal lithium, potassium, sodium, chloride, fluoride temperature trifluoride oxygen fluorine, the velocity is high, can get almost all chemical liquid ( Which also contains concentrated nitric acid and aqua regia) The highest temperature, PTFE material ability to 176. 6 degrees, but because the diaphragm in within diaphragm pump products used for reciprocating work back and forth, we suggest within the temperature of 120 degrees to use, only if the pump body metal materials produced by pump body must be used. Plastic water pump body is PVDF material pump body heat resistance is highest in 93. Less than 3 degrees.

5, the corrosion resistance of fluorine rubber diaphragm is more ideal, can be applied to all kinds of acidic medium (usually Including the concentrations in the oxidizing acid) And alkaline liquid, salt medium, oil medium, hydrocarbon class media, etc. Fluorine rubber heat-resistant maximum temperature 176. 6 degrees, but price of fluorine rubber diaphragm is higher, if the corrosive medium temperature within 80 degrees we recommend of ptfe diaphragm teflon inside lining rubber diaphragm choose normal butyl rubber diaphragm can the qing, if conveying fluid is higher than 80 degrees within 120 degrees when we recommend contact liquid membrane of ptfe diaphragm inside lining rubber diaphragm with fluorine rubber diaphragm is the best choice.

6, mountain rubber diaphragm has good wear resistance, and corrosion resistance and heat resistance, and is generally applied to acid and alkali liquid, cannot send containing solvent liquid, can replace epdm material, rubber diaphragm maximum temperature to 104 degrees can road, we recommend that you use within 80 degree.

7, polyether rubber diaphragm has better wear resistance, mainly used in oil liquid, the qing can replace butyl rubber diaphragm, resistance to temperature at 100 degrees, also should be used within 80 degree.

8, epdm diaphragm, wear resistance and resistance to aging, but also resistant to ozone and regular soda acid liquid, high of 120 degrees heat resistance, should be used within 100 degree.

9 the qing, butyl rubber is one of the most common rubber diaphragm of diaphragm, and is suitable for conveying various no corrosive liquid, can also be used for oil medium, the highest 100 degrees of heat-resistant, suggested that medium used within 80 degree.

the above data show that the ability of the pneumatic diaphragm pump within the answer is 120 degrees, how high temperature of pump body must use metal materials of the pump body, diaphragm outer adopts teflon material lining materials using fluorine rubber or epdm materials that ability to 120 degrees within the liquid, it is important to note of 120 degrees liquid long-term use of pneumatic diaphragm pump diaphragm life will have an effect.
