QBY series not only pump liquid,but also transport any medium which difficult in flowing ,they have many advantge of self priming pump, submersible pump canned pump, and impurity pump.

Dont need irrigate and lead water, the pump head can reach to 70mm,and outlet pressure 6kgf/cm2.

flowing roomily and passing performance is good,that can pass the solid grain whose max diameter is lomm, it wont result in many wear and teer when passing slurry and impurity.

Head and capacity realizd nonpolar adjust by air-valve opening dearee (lair pressure-adjusting is at 1-7kgf/cm2.

This pump doesn't have rotary parts and shaft seal,the septclm separate the medium which are pumped and the pumps stir parts,so that the passed medium wont be leakaged,therefore,it wonresult in evironmental pollution and bad to people, when transport poisonous and corrosive medium.It is safe and reliable on the combustible and explosive occasions.

Can operate while it is im merged in water.

Easily to use, operating reliably,only need open and turn off the air-valve that make it start and stop,even if long-lime on medium running or stop suddenly because of accidental status,pump still be good,Besides, it will stop by itself when it is over-loading, and it can keep safe by itself, and go on running when load come back to be normal.

Simple structure,less parts which are easy to be destroyed, be easily to install, and convenient to maintain. The passing medium wont come into contact with equiped air-valve and other stir parts,which dont like other pumps make for performances descend which caused by wear and tear of rotor,plunger,gear wheel,vane and other parts.

Can passing stick liquid.

It neednt be lubricated with Oil, it wont influence the pump, even if empty runing ,thats one of the marked features.
