Product Details

Pneumatic diaphragm pumps can not only pump flowing liquids, but also transport some non flowing media, and have many advantages over other conveying machinery such as self-priming pumps, submersible pumps, shielded pumps, mud pumps, and impurity pumps.

1. No need for irrigation, with a suction lift of up to 7M, a head of 50M, and an outlet pressure of 6kgf/cm2.

2. Wide flow shielding, good performance, allows for the passage of the largest particles, with a diameter of up to 10mm, and has minimal wear on the pump when pumping mud and impurities. 3. The head and flow can be infinitely adjusted through the opening of the air valve. (Adjust the air pressure between 1-7kg/cm2).

4. The pump has no rotating parts and no shaft seal diaphragm to separate the pumped medium from the moving parts of the pump. The working medium is completely separated, and the conveyed medium will not leak outward.

So when pumping toxic, volatile or corrosive media, it will not cause environmental pollution and endanger personal safety. 5. No need for electricity, safe and reliable to use in flammable and explosive places.

6. Can work submerged in a medium.

7. Easy to use, reliable in operation, the pump can be started and stopped simply by opening and closing the gas valve. Even if there is no medium operation for a long time or sudden shutdown due to unexpected situations, the pump will not be damaged. Once overloaded, the pump will automatically shut down, with self-protection performance. When the load returns to normal, it can also

Activate and run.

8. The pump has a simple structure and few vulnerable parts. It is easy to install and maintain, and the medium transported by the pump does not come into contact with moving parts such as valve reading and connecting rods. Unlike other types of pumps, the performance gradually decreases due to wear and tear of components such as rotors, pistons, gears, and blades. 9. Can transport viscous liquids. (viscosity below 10000 centipoise)

10. This pump does not require oil lubrication and has no impact on the pump even when idling. This is a major feature of the pump.

1. Pump peanut butter, kimchi, mashed potatoes, red sausage, jam apple puree, chocolate, etc.

2. Pump paint, gum, and pigment.

3. Adhesive and glue, all types can be pumped up.

4. Various types of tiles, porcelain, bricks, and ceramic glazes.

5. After drilling the oil well, use a pump to suck up sediment and grout.

6. Pump various emulsions and fillers. ．

7. Pump various types of sewage.

8. Use a pump as an oil tanker and a barge to clear and extract sewage from the warehouse.

9. Hops and fermented powder slurry, syrup, sugar dense.

10. Pump water from mines, tunnels, ore dressing, and slag. Pump cement grout and mortar.

11. Various rubber pastes.

12. Various abrasives, corrosives, petroleum and mud, cleaning oil stains, and general containers.

13. Various highly toxic, flammable, and volatile liquids.

14. Various strong acids, strong alkalis, and highly corrosive liquids.

15. Various high-temperature liquids can withstand up to 150 ℃.

16. As a front-end pressure feeding device for various solid-liquid separation equipment.

1. Cleaning the bottom of the oil tank, although there is a cushion method for oil pumping, cannot guarantee that the oil will be completely pumped out, and there will always be at least 3-5mm thick oil layer left on the surface. Taking a 5000m3 oil tank as an example, approximately 1-1.5t of oil is lost each time. For oil tanks with low-level dehydration tanks, although the remaining oil and water can be discharged to the oily wastewater treatment plant for recycling, the volatile oil products are mostly evaporated during transportation and pollute the environment.

2. During the process of oil refining production scheduling, temporary tank dumping, loading and unloading, and oil sampling are often required for oil products. Or to avoid contaminating normal pipelines, usediaphragm pumpConnecting temporary pipelines can quickly and conveniently complete this task.

3. A 3000t oil tanker is unloaded using a fixed screw pump for bottom oil recovery. At least 50t of oil should remain between the warehouse partitions. If a larger displacement isolation pump is used, good results can be achieved.

4. The transportation of gas and hydrogen sulfide residue at the bottom of the refinery flare requires centralized discharge and treatment of gas residue and sulfur-containing water, otherwise it will form acidic corrosion equipment.

5. Ceramic industry: Use this pump to extract glaze slurry and can be used to supply pressure to a filter press.

6. During the maintenance of drainage well pipelines, valves, and underground ditches, it is necessary to remove waterlogging and dirty oil. Although using a submersible pump can completely drain the water, these places are often far away from the power source, which is very inconvenient. Can a diaphragm pump be used for pressure? Gas cylinders are used as power to recover contaminated oil and drain water.

7. The cleaning of sewage treatment plants and sludge tanks. The sludge tanks in sewage treatment plants often accumulate a large amount of oil sludge and silt, which need to be cleaned. Diaphragm pumps are used for flexible suction, which is convenient, labor-saving, and time-saving.

8. The liquefied gas pump room and laboratory are used to drain waterlogging. Due to the low terrain and first level fire prevention zone, using diaphragm pumps to drain waterlogging is safer and much more efficient than using water or steam pumps.

In addition, this pump has its own advantages in applications such as refining and transferring materials for cyclic acids, transporting sodium sulfite liquids for loading and unloading, and loading and unloading benzene raw materials.
