QBY air operated pneumatic diaphragm pumps not only can exhaust the flow liquid, but also can convey some uneasy flowed medium, with the merits of self-pumping pump, diving pump, shield pump and impurity pump etc.
Overview
Superiority:
1. Unnecessary to pour the drawing water;
2. Wide flow and good performance. The diameter allowed to pass the Max grain reaches10mm;
3. Less damage to the pump while exhausting the slurry and impurity.
4. The delivery Head and flow can pass the pneumatic valve open to realize the stepless adjustment;
5. The diaphragm will completely separate the exhausted medium and pump running parts, working medium;
6. Safe and reliable while using in the flammable and explore places; toxin and flammable or corrosive medium;
7. Needn’t the oil lubricant and idling is ok.
