The QBY series pump is a diaphragm pump. It is also known as a Membrane pump, Air Operated Double Diaphragm Pump or Pneumatic Diaphragm Pump or AODD pump. This is a positive displacement pump. The pump uses a combination of the reciprocating action of a rubber, thermoplastic or Teflon diaphragm and suitable valves either side of the diaphragm to pump a fluid.
The QBY diaphragm pumps are driven with compressed air without the need of electric power. Widely used for leak proof applications in industries like petrochemical chemical metallurgy and ceramics etc. Applicable to liquids of leaky corrosive inflammable and explosive & hazardous properties.

When the volume of a chamber of either type of pump is increased (the diaphragm moving up), the pressure decreases, and fluid is drawn into the chamber. When the chamber pressure later increases from decreased volume (the diaphragm moving down), the fluid previously drawn in is forced out. Finally, the diaphragm moving up once again draws fluid into the chamber, completing the cycle. This action is similar to that of the cylinder in an internal combustion engine.
If you are interested in QBY air diaphragm pump, just contact us SIKOPUMP freely.
The separate QBY pump catalog and detailed specification can be provided.
There are two sets of diaphragms for each pump, and two layers for each set of diaphragms.
So totally there are four pcs of diaphragms for each pump.
The inside layer of diaphragm is in Santoprene, and the outside layer of diaphragm is in PTFE, which is contacted with the liquid.
When for the high corrosive liquid, the ball valve and valve seat material is in PTFE, otherwise they are in Santoprene
