QBY3 Pneumatic Diaphragm Pump using compressed air as the power source, for all kinds of corrosive liquid, liquid with particles, high viscosity, volatile, flammable, highly toxic liquid, can be pumped up, especially suitable for flammable and explosive field.Product operation, safe and reliable, corrosion resistance, durable, with self-absorption, no-loss, a variety of materials, a wide range of USES, simple device, free of maintenance.
QBY3 pneumatic diaphragm pump product overview:
QBY3 series pneumatic diaphragm pump produced by KEMAI in China is a new type of conveying machinery, using compressed air as the power source, conveying a variety of corrosive liquid, liquid with particles, high viscosity, volatile, flammable, toxic liquid.Its performance parameters are similar to those of WLLDENPVMPS in federal Germany and MARlOWPUMPS in the United States.
QBY3 pneumatic diaphragm pump product advantages:
QBY3 pneumatic diaphragm pump can pump the flow of liquid, and can transport some not easy to flow medium
1. No irrigation is needed.The suction distance is up to 5m.The head reaches 70m~84m.Outlet pressure ≥7bar~8.4bar.
2, through the performance of good, spacious flow.Maximum particle diameter up to 10mm is allowed.Pumping mud, containing impurities of liquid, little wear on the pump;
3. Head and flow can be stepless adjusted through the opening degree of the air valve (the air pressure is adjusted between 1 and 8.4 bar) :
4. The pump has no rotating parts, no shaft seal, diaphragm and other pumped media are completely separated from the moving parts, work pieces and media of the pump, and the transported media will not leak out.So pumping toxic, easy to play or corrosive media, will not cause environmental pollution and harm personal safety;
5. No electricity.Safe and reliable in inflammable and explosive working environment;
6, can be immersed in the medium:
7, start, stop just open and close the gas valve.The pump will not be damaged even if it runs for a long time without medium or stops suddenly due to unexpected circumstances.Overload, the pump will automatically ground stop, with self-protection performance, when the load returned to normal, and can automatically start operation;
8, the pump structure is simple, easy to install, maintenance, pump transport medium will not contact with the valve, coupling rod and other moving parts, unlike other types of pumps due to the wear of rotor, piston, gear, blade and other parts and performance gradually decreased;
9. It can transport relatively viscous liquid (viscosity is less than 10,000 centipores) :
10, the pump does not need oil lubrication, idling has no impact on the pump.

QBY3 Pneumatic Diaphragm Pump Body and diaphragm material has PP,PE,PVDF,PTFE:
PP Polypropylene (PP Polypropylene, hereinafter referred to as PP) is a semicrystalline thermoplastic plastics.High impact resistance, strong mechanical properties, resistance to a variety of mail solvents and acid – base corrosion.PP has non-toxic, tasteless, small degree, strength stiffness, strength and heat resistance are better than low-pressure polyethylene, can be used in about 80.
PE polyethylene (Poiyethyiene) is a kind of thermoplastic resin obtained by polymerization of ethylene.In industry, copolymers of ethylene with a small amount of a- ene are also included.Polyethylene odorless, non-toxic, feel like wax, with excellent low temperature resistance, good chemical stability, can withstand most acid and alkali erosion.Insoluble in ordinary solvents at room temperature, small water absorption, good electrical insulation wire.
PVDF polyvinylidene fluoride, appearance is translucent or white particles, fission chain between the closely packed, and have strong ammonia key, oxygen index was 46%, long-term use of temperature of 40-150 – degrees, PVDF resin with resin and general resin features, in addition to have good resistance to chemical corrosion resistance, high temperature resistance, oxidation resistance, weather resistance, radiation resistance, also has the piezoelectric, dielectric, pyroelectric and other special performance.
PTFE polytetrafluoroethylene (Tefion or PTFE), commonly known as the “king of plastics”, commonly known as “non-stick coating”, is made of polytetrafluoroethylene by polymerization of polymer compounds, with excellent chemical stability, corrosion resistance, sealing, high viscosity, electrical insulation and good anti-aging resistance.It can be used as engineering plastics to manufacture ptfe tubes, rods, strips, plates, films, etc.
