Pneumatic diaphragm pump

Pneumatic diaphragm pump is a new type of conveying machinery that uses compressed air as the power source. It can pump and absorb various corrosive liquids, liquids with particles, high viscosity, volatility, flammability, and highly toxic liquids.

Pneumatic diaphragm pump is a new type of conveying machinery and a novel type of pump in China. Using compressed air as the power source, it can be used for various corrosive liquids.

Pneumatic diaphragm pumps have four types of materials: engineering plastics, aluminum alloy, stainless steel, and cast iron. Pneumatic diaphragm pumps use nitrile rubber, chloroprene rubber, fluororubber, polytetrafluoroethylene, polytetrafluoroethylene, etc. according to different liquid media to meet the needs of different users. Placed in various special occasions, it is used to pump media that cannot be pumped by conventional pumps, and has achieved satisfactory results.

Applicable occasions:

Due to the above characteristics, pneumatic diaphragm pumps have gradually entered the market of other pumps and occupied a part of it since their inception. For example, in the paint and ceramic industries, pneumatic diaphragm pumps have taken an appropriate leading position, while in other industries such as environmental protection, wastewater treatment, construction, sewage discharge, and excellent chemical engineering, their market share is expanding and they have a good position in the quality of other pumps.

Pneumatic diaphragm pump is a new type of conveying machinery and a novel type of pump in China. Using compressed gas as the power source, various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids can be pumped and absorbed completely. There are four types of materials for pneumatic diaphragm pumps: plastic, aluminum alloy, cast iron, and stainless steel. Pneumatic diaphragm pumps use nitrile rubber, chloroprene rubber, fluororubber, polytetrafluoroethylene, and polytetrafluoroethylene according to different liquid media. To meet the needs of different users. Placed in various special occasions, it is used to pump media that cannot be pumped by conventional pumps, and has achieved satisfactory results.

1. Due to the use of gas as power, the flow rate actively adjusts with changes in back pressure (outlet resistance), making it suitable for medium to high viscosity fluids. The working point of the centrifugal pump is set based on water. If it is used for fluids with slightly higher viscosity, it is important to adhere to the contract and provide a gearbox or variable frequency speed controller, which can significantly increase the cost. This is also true for gear pumps.

2. The use of pneumatic pumps in flammable and explosive environments is excellent and cost-effective, such as the transportation of fuel, gunpowder, and explosives, because:

1、 Sparks cannot be generated after grounding;

2、 No heat is generated during work, and the machine will not overheat;

3、 The fluid will not overheat because pneumatic diaphragm pumps have less agitation on the fluid.

3. In the harsh environment of construction sites, such as the discharge of wastewater from construction sites and industrial mines, due to the high amount of impurities and complex composition in the wastewater, the pipeline is prone to blockage, which creates an environment with high load on the electric pump and makes the motor prone to overheating and damage. The pneumatic diaphragm pump can pass through particles and the flow rate is adjustable, and it automatically stops when the pipeline is blocked.

4. In addition, the pneumatic diaphragm pump has a small volume and is easy to move, does not require foundation, occupies a small area, and is easy to install and economical. Can be used as a mobile material conveying pump.

5. In the handling of hazardous and corrosive materials, diaphragm pumps can isolate all materials from the outside world.

6. Or in some experiments, protect the raw materials from impurities and contamination.

7. Can be used to transport fluids with relatively unstable chemical properties, such as photosensitive materials, flocculants, etc. This is because the shear force of the diaphragm pump is low, which has little physical impact on the material.
