1. Its unnecessary to pour the drawing water, the suction lift reaches 7m height, the delivery lift reaches 70m length and the export pressure≥6kgf/cm2;

2. Wide flow and good performance. The diameter allowed to pass the max grain reaches 10mm. The damage is very less to the pump while exhausting the slurry and impurity.

3. The delivery lift and flow can pass the pneumatic valve open to realize the stepless adjustment ( the pneumatic pressure adjustment is between 1-7kgf/cm2);

4. This pump has no rotary parts and no bearing seals. The diaphragm will completely separate the exhausted medium and pump running parts, working medium. The convey medium cant be leaked outside. Thus it will not cause the environmental pollution and human body safety dangerous while exhausting the toxin and flammable or corrosive medium.
