The **QBY Pneumatic Diaphragm Pump** is a modern and innovative conveying machine that has gained significant popularity in China. Powered by compressed air, this pump is capable of handling a wide range of challenging liquids, including corrosive, viscous, volatile, flammable, and highly toxic substances. Its performance is comparable to leading international models such as WLLDENPVMPS from Germany and MARIOWPUMPS from the United States.
The QBY series is available in eight different sizes, ranging from 10mm (3/8") up to 100mm (4"), offering flexibility for various applications. It is constructed using four primary materials: aluminum alloy, cast iron, engineering plastics, and stainless steel. Depending on the type of liquid being transported, different diaphragm materials are used, such as NBR, neoprene, fluororubber, and polytetrafluoroethylene, ensuring compatibility and durability.
Since its introduction in 1986, the QBY pump has been widely adopted by over 1,000 units across industries such as petroleum, chemical, electronics, ceramics, and textiles. It excels in special environments where conventional pumps cannot operate effectively, making it an essential tool in many industrial settings.
**Key Features of the QBY Pneumatic Diaphragm Pump:**
1. No need for water priming; can lift up to 7 meters and discharge up to 50 meters with a pressure of at least 6 kgf/cm².
2. Excellent flow capacity and particle passage ability, allowing particles up to 10 mm in diameter to pass through without causing damage.
3. Adjustable head and flow by controlling the air valve, with air pressure ranging from 1 to 7 kgf/cm².
4. No rotating parts or shaft seals, which ensures no leakage of hazardous or corrosive media.
5. Safe to use in explosive environments due to the absence of electrical components.
6. Can be submerged in the medium for operation.
7. Simple operation with easy start and stop functions, and self-protection features in case of overload.
8. Minimal wear parts and a simple design make maintenance straightforward.
9. Capable of pumping highly viscous liquids (viscosity below 10,000 cP).
10. No oil lubrication required, even during idle operation.
**Applications of the QBY Pneumatic Diaphragm Pump:**
- Transporting food products like peanut butter, jam, chocolate, and sauces.
- Handling paints, adhesives, pigments, and glazes.
- Pumping sewage, sludge, cement grout, and other industrial waste.
- Moving abrasive, corrosive, and high-temperature liquids.
- Used in mining, construction, and oil drilling operations.

In addition to these uses, the QBY pump serves as a pre-pressure supply device for solid-liquid separation systems, further expanding its utility in industrial applications.
Plant enzymes are indispensable for plant metabolism and are critical determinants of the extensive chemodiversity observed in plants. These enzymes serve as primary catalysts in biosynthetic pathways, enabling the biosynthesis of a diverse range of secondary metabolites, such as alkaloids, terpenes, and phenolics.

It is now divided into seven categories: oxidoreductases, transferases, hydrolases, lyases, isomerases, ligases and translocases. The International Commission on Enzymology divides enzymes into seven categories based on the nature of the enzymatic reaction, the nature of the transfer reaction, and the types of group donors and group acceptors, namely: oxidoreductases, transferases, hydrolases, lyases, isomerases, ligases and translocases.
