1, due to the use of air for power, so the flow rate with the change in back pressure (outlet resistance) and automatic adjustment, suitable for use in high viscosity fluids. The working point of the centrifugal pump is set with water as the benchmark, if used for slightly higher viscosity fluids, it is necessary to support the reducer or frequency converter, the cost is greatly increased, for gear pumps is the same.
2, pneumatic diaphragm pump in a flammable and explosive environment with pneumatic pumps reliable and low cost, such as fuel, gunpowder, explosives delivery, because: first, grounding is unlikely to produce sparks; second, no heat generated in the work, the machine will not overheat; third, the fluid will not overheat because the diaphragm pump on the fluid stirring minimum.
3, in poor places on site, such as construction sites, industrial and mining wastewater discharge, due to the impurities in the sewage and complex composition, the pipeline is easy to block, so that the electric pump will form a high load, the motor is hot and fragile. Pneumatic diaphragm pump can pass particles and adjustable flow, the pipeline is blocked automatically stop to clear.
4, in addition, the pneumatic diaphragm pump is small and easy to move, no foundation, occupying very little ground, easy and economic installation. Can be used as a mobile material transfer pump.
5, In the handling of hazardous and corrosive materials, diaphragm pumps can be completely separated from the outside world.
6, pneumatic diaphragm pumps can be used to convey chemically unstable fluids, such as: photographic materials, flocculation fluid, etc.. This is because of the low shear force of the diaphragm pump, the physical impact on the material is small.
1, spacious flow, through good performance, allowing the passage of grain size up to 10 mm. pumping mud, impurities, little wear on the pump.
2, pneumatic diaphragm pumps do not need to be filled with priming water, suction range up to 5-9 m (dry or wet), head up to 70 m, outlet pressure of 7 bar.
3, pneumatic diaphragm pump without rotating parts, no shaft seal, diaphragm and other pumped media and pump moving parts, workpiece media completely separated, the media conveyed will not leak outward. So when pumping toxic, volatile or corrosive media, it will not cause environmental pollution and endanger personal safety.
4, Head and flow can be steplessly adjusted by the opening of the air valve (air pressure adjustment between 1-7 bar)
5, Can be submerged in the media work
6, no need to use electricity, in flammable, explosive places to use safe and reliable
7, pneumatic diaphragm pump structure is simple, less wearing parts, the pump structure is simple, easy to install, easy to maintain, the pump conveys the medium will not touch the valve, linkage and other moving parts, unlike other types of pumps due to rotor, piston, gear, vane and other parts of the wear and tear of the performance gradually decline.
8, easy to use, reliable work, open and close simply open and close the gas valve, even if due to unforeseen circumstances and a long time without media operation or sudden stop pump will not be damaged, once overload, the pump will automatically stop, with self-protection performance, when the load is restored to normal, and can automatically start running;.
9, pneumatic diaphragm pump without oil lubrication, even if idle, there is no impact on the pump, which is a major feature of the pump.
10, can convey more viscous liquids (viscosity below 20,000 centipoise).
