QBK series pneumatic diaphragm pump for all kinds of corrosive liquid, with particles, high viscosity, volatile, explosive, highly toxic liquid, ceramic glaze slurry, jam, glue, oil tanker bin bottom recovery, temporary pour tank and other liquids can be suction, with self-priming pump, submersible pump, shield pump, mud pump and impurity pump and other transport machinery many advantages. The pump body flows through the parts of stainless steel, aluminum alloy, cast iron, plastic, diaphragm according to different liquids respectively using butadiene rubber, fluorine rubber, neoprene rubber and PTFE four.
1. No irrigation water, suction up to 7m, head up to 50m;
2. Spacious flow, pumping mud, impurities, little wear to the pump;
3. The head and flow can be stepless adjusted by the opening of the air valve;
4. No rotating parts, no shaft seal, conveying medium will not leak, pumping toxic, volatile and other media, will not cause environmental pollution and harm personal safety;
5. No need to use electricity, safe and reliable in flammable and explosive occasions;
6. Can be immersed in the medium to work;
7. Easy to use, reliable work, start and stop simply open and close the gas valve, once overload, the pump will automatically stop, with self-protection performance, when the normal, and can automatically start operation;
