Pneumatic diaphragm pump is a new type of delivery pump, which uses compressed air as the power source and can be used for various corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids.
1. Use gas as power, so the flow is actively adjusted with the change of air pressure, suitable for medium and high viscosity fluids.2. Pneumatic pumps are reliable and low-cost in flammable and explosive environments, such as the delivery of fuel, gunpowder, and explosives, because:First, it is impossible to generate sparks after grounding;Second, no heat is generated during work, and the machine will not overheat;Third, the fluid does not overheat because the air-operated diaphragm pump has minimal agitation of the fluid.3. In the harsh center of the construction site, such as construction site, industrial and mining wastewater discharge, because the impurities in the sewage are easy to block, the load on the electric pump is too high, and the motor is easily damaged by heat. The air-operated diaphragm pump can pass particles and has an adjustable flow rate, and automatically stops when the pipeline is blocked.4. In addition, the pneumatic diaphragm pump is small and easy to move, does not require foundation, occupies a small area, and is easy and economical to install. Can be used as a mobile material delivery pump.5. In the treatment of hazardous and corrosive materials, the diaphragm pump can completely isolate the materials from the outside world.6, or in some experiments to ensure that no impurities contaminate the raw materials.7. It can be used to transport fluids with unstable chemical properties, such as photosensitive materials, flocculation liquid, etc. This is because of the low shear force of the diaphragm pump, which has little physical impact on the material.
