AOK80 PVDF self priming pneumatic duplex diaphragm pump can always remain efficient, not because of wear and tear and reduce efficiency. AOK80 PVDF air diaphragm pump can make 100% of the energy utilization, When the pneumatic diaphragm pump outlet is closed, the 3 inch PVDF air operated duplex diaphragm chemical pump will automatically stop. There is no equipment movement, wear, overload, heating phenomenon.
80mm plastic irrigation pneumatic duplex diaphragm pump pumping liquid medium is not only the flow of liquid, but also can transport some not easy to flow of liquid medium, 3 inch Polypropylene air driven diaphragm pump has self-priming pump, mud pump, impurities pump and other comprehensive advantages.
AOK80 food grade stainless steel air operated diaphragm water pump is a high quality pneumatic diaphragm pump, but also a high flow air membrane pump. through the diaphragm and pump body formed between the sealing chamber, the sealing is effective and reliable, the medium will not leak to the outside world.
AOK aluminum air driven diaphragm pump simple structure, less wearing parts, At the same time, the slurry double diaphragm pump is a kind of corrosion resistant pneumatic diaphragm pump, And it can transport viscosity within the range of 10000 centipores of liquid.
2 inch stainless steel pneumatic diaphragm pump is a chemical resistant diaphragm pump, and it is Suitable for medium and high viscosity fluid, is a liquid transfer air diaphragm pump.
AOK50 PVDF self priming AODD pump is easy to use, reliable and simple to operate. When the 2inch PVDF air powered diaphragm pump accident will automatically stop, with good self-protection performance. When the AOK50 pneumatic diaphragm pump everything back to normal, and can automatically start running.
2 inch plastic self priming diaphragm pump has a very strong self-priming function. The use of 2 inch pp air diaphragm pump without rotating parts, dry and wet absorption can be achieved.
Flexible Hose: Explosion-proof flexible connecting pipe is suitable for combustible dust environment, It has the advantages of fire resistance, corrosion resistance, water resistance, aging resistance, good flexibility, firm structure and reliable operation. Chemical hose: Can be widely used to transport corrosive chemical liquids and gases, excellent chemical resistance. The special construction process makes it cost-effective, light, soft, easy to operate and durable.
AOK50 High Viscosity Medium Air Operated Reciprocating Self Priming Diaphragm Pump without oil lubrication, even idling on the pump without any impact.
Stainless steel pneumatic diaphragm pump for chemical in the transportation of hazardous and corrosive liquids, the liquid can be completely separated from the outside world. It is a kind of corrosion resistant chemical diaphragm pump.
AOK40 PVDF pneumatic diaphragm pump powered by compressed air, when the 1.5 Inch Compressor Air Diaphragm Pump exhaust is an expansion endothermic process. And the AOK40 PVDF self priming pneumatic duplex diaphragm pump working temperature is reduced, no harmful gas discharge.
1.5 inch Polypropylene air operated duplex diaphragm pump polypropylene material density is relatively small, is also one of the lightest plastic diaphragm pump material. Therefore, the 1.5 inch pp pneumatic diaphragm pump is very light and convenient and has strong mobility.
316 food grade sanitary pneumatic diaphragm pump is a kind of excellent performance, has more corrosion resistance, more wear resistance, more high temperature resistance and other high-quality pneumatic diaphragm pump. For example, our sanitary pneumatic diaphragm pump can be used in the daily chemical industry.
1.5 inch AOK high performance air operated diaphragm pump can be used according to different liquid medium different materials, in order to meet the needs of different users.
Stainless steel aodd pump can be used as mobile material delivery pump. 25mm stainless steel aodd pump is not only small in size, but also easy to move, no need for foundation, small footprint, simple and economical installation.
