Product Overview of QBY Stainless Steel Pneumatic Diaphragm Pump

Pneumatic diaphragm pump is a novel positive displacement pump in China that uses compressed air as the power source, distributes air through the reciprocating motion of air valves, and drives the diaphragm to squeeze and transport media. This pump combines the advantages of conveying machinery such as impurity pumps, self-priming pumps, mud pumps, shield pumps, and submersible pumps. This series of pumps has the characteristics of beautiful structure, good physical resistance, durability, etc. It can pump and absorb various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, explosive, highly toxic liquids, ceramic glaze slurry, fruit slurry, glue, oil tanker bottom oil recovery, temporary tank pouring and other liquids completely. Especially, it can solve the problems of running, emitting, dripping, leaking and not allowing idle running of blade pumps. This series of products can use ordinary clean industrial gas or instrument gas to start at a low pressure of 0.1 kg, saving more than 30% of gas consumption under normal transportation conditions. It is a new generation of energy-saving pump with good market prospects. Its performance parameters are similar to WLLDENPUMPS from Germany and MARIOWPUMPS from the United States.

At present, QBK pneumatic diaphragm pumps are produced on a large scale in six varieties: cast iron, aluminum alloy, stainless steel, engineering plastics, pump fluorine lining, and pump rubber lining. Users can choose according to the characteristics of the conveying medium,

Design Features of QBY Stainless Steel Pneumatic Diaphragm Pump

1. Pneumatic diaphragm pump compresses air as power.

2. Pneumatic diaphragm pump is a type of displacement pump that causes volume changes due to the reciprocating deformation of the diaphragm. Its working principle is similar to that of a plunger pump. Due to the characteristics of the working principle of diaphragm pumps, diaphragm pumps have the following features:

(1) Pneumatic diaphragm pump will not overheat: compressed air is used as power, and during exhaust, it is a process of expansion and heat absorption. The temperature of the pneumatic pump decreases during operation, and no harmful gases are discharged.

(2) Pneumatic diaphragm pump does not generate electric sparks: Pneumatic diaphragm pump does not use electricity as power, and after grounding, it prevents electrostatic sparks

(3) Pneumatic diaphragm pumps can handle liquids containing particles: due to their volumetric operation and ball valve inlet, they are not easily clogged.

(4) Pneumatic diaphragm pump has extremely low shear force on materials: how it sucks in and how it discharges during operation, so it has little agitation on materials and is suitable for transporting unstable substances

(5) The flow rate of the pneumatic diaphragm pump can be adjusted, and a throttle valve can be installed at the material outlet to regulate the flow rate.

(6) Pneumatic diaphragm pumps have self-priming function.

(7) Pneumatic diaphragm pumps can run empty without any danger.

(8) Pneumatic diaphragm pumps can operate underwater.

(9) Pneumatic diaphragm pumps can transport a wide range of pumps, from low viscosity to high viscosity, and from corrosive to viscous.

(10) Pneumatic diaphragm pumps do not have complex control systems, cables, fuses, etc.

(11) Pneumatic diaphragm pumps have small volume, light weight, and are easy to move.

(12) Pneumatic diaphragm pumps do not require lubrication, so maintenance is simple and there will be no pollution to the working environment due to dripping.

(13) Pneumatic diaphragm pumps can always maintain high efficiency and will not decrease due to wear and tear.

(14) Pneumatic diaphragm pump utilizes 100% of its energy. When the outlet is closed, the pump automatically shuts down, causing equipment movement, wear, overload, and heating

(15) Pneumatic diaphragm pumps do not have dynamic seals, making maintenance simple and avoiding leaks. There are no dead spots during work.

Product Features of QBY Stainless Steel Pneumatic Diaphragm Pump

1. QBK type pneumatic diaphragm pump does not require water injection, with a suction stroke of up to 7m, a head of 50m, and an outlet pressure of ≥ 6kgf/cm2;

2. The QBK pneumatic diaphragm pump has spacious flow and good passing performance, allowing for the passage of large particles with a diameter of up to 10mm. When pumping mud and impurities, it causes minimal wear on the pump;

3. The head and flow rate of QBK pneumatic diaphragm pump can be infinitely adjusted through the opening of the air valve (the air pressure can be adjusted between 1-7kgf/cm2);

4. The pump has no rotating parts and no shaft seal. The diaphragm completely separates the pumped medium from the moving parts and working medium of the pump, and the conveyed medium will not leak outward. So when pumping toxic, easily reactive or corrosive media, it will not cause environmental pollution and endanger personal safety;

5. QBK pneumatic diaphragm pump does not require electricity and is safe and reliable to use in flammable and explosive places;

6. QBK type pneumatic diaphragm pump can work immersed in the medium;

7. The QBK type pneumatic diaphragm pump is convenient to operate, reliable in work, and can be easily started and stopped by simply opening and closing the gas valve. Even if it runs for a long time without medium or suddenly stops due to unexpected situations, the pump will not be damaged. Once overloaded, the pump will automatically stop, with self-protection performance. When the load returns to normal, it will automatically start and run again;

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 the valve and connecting rod. Unlike other types of pumps, the performance gradually decreases due to wear and tear of components such as rotors, pistons, gears, and blades;

9. QBK pneumatic diaphragm pump can transport relatively viscous liquids (viscosity below 10000 centipoise);

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

Application Example of QBY Stainless Steel Pneumatic Diaphragm Pump

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. Alternatively, in order to avoid contaminating normal pipelines, connecting temporary pipelines with a diaphragm pump can quickly and conveniently accomplish 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 diaphragm 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.

Precautions for using QBY stainless steel pneumatic diaphragm pump

1. The vibration of this pump is extremely slight, and in general, it is not necessary to install foot bolts.

2. If dirt enters the compressed air, it will affect the normal start of the pump. It is recommended that users install an air filter. (The general manager already exists, but if there is, it can be waived)

3. Easy to suction; When dealing with the medium in Dongjie, a valve should be installed at the inlet of the pump. When the pump is stopped, the valve should be closed first, and then the pump should be turned on for a few minutes until the medium in the pump body is completely discharged to avoid difficulties in starting the pump again.

4. When replacing the diaphragm, the connecting rod and copper sleeve inside the pump must be cleaned thoroughly, and the white PTFE sealing ring should not be damaged. Simply install it as it is and it can be used.
