SEMICON China 2025: Technological Innovation of Chemical Pumps Drives Semiconductor Industry Revolution

- New Trends of High Efficiency, Reliability and Intelligence

As the core event in the global semiconductor industry chain, SEMICON China 2025 has once again become a technology barometer. As the semiconductor manufacturing industry moves towards finer processes (such as chips below 2nm) and green manufacturing, the technological innovation and reliability of chemical pumps, as the "heart equipment" in the process flow, have become the focus of the exhibition.

I. High-Purity Materials and Corrosion Resistance: Meeting the Demands of Extreme Processes

Semiconductor production involves strong acids (such as hydrofluoric acid), strong alkalis (such as potassium hydroxide), and high-purity chemical reagents, posing extremely demanding requirements for the corrosion resistance and purity of pump materials. At this exhibition, multiple companies introduced magnetic drive chemical pumps made of high-purity PTFE, ceramic coatings, or lined with zirconium alloys. These pumps feature leak-free performance, corrosion resistance, and easy maintenance. For example, a German manufacturer showcased a CVD process dedicated pump. Through nano-coating technology, the particle release amount was reduced to less than 0.1μm, meeting the semiconductor manufacturing industry's extremely strict standards for micro-contamination.

II. Energy Efficiency Optimization and Intelligence: The New Engine of Green Manufacturing

In response to the global trend of carbon neutrality, energy efficiency upgrade of chemical pumps has become a key focus. Permanent magnet brushless motor direct drive technology and AI adaptive flow control algorithm have become key terms. A Chinese company released an intelligent pump group management system that can monitor the vibration, temperature, and flow fluctuations of the pump body in real time. Through digital twin technology, it can predict faults and reduce energy consumption by 30%. In addition, variable frequency drive technology combined with dynamic speed adjustment according to process requirements has become crucial for production line cost reduction and efficiency improvement.

III. Modular Design and Domestic Substitution: The Rise of Local Manufacturers

In response to the rapid model change requirements of semiconductor production lines, modular quick-installation pump bodies have become a new trend. Domestic manufacturers such as China Micro Semiconductor Pump Industry exhibited detachable corrosion-resistant pump modules that support cleaning and medium switching within 24 hours, suitable for multiple scenarios such as IC front-end wet etching and photovoltaic PERC cleaning. At the same time, the exhibition set up a "Domestic High-End Pump Technology Zone" for the first time. The domestication rate of domestic pumps in the 14nm process has reached 65%, and in some areas, technological counter-surpassing has been achieved.

IV. Market Opportunities and Competitive Landscape

Data from SEMI shows that the market size of China's semiconductor equipment is expected to exceed $60 billion in 2025, with chemical pumps accounting for about 12%, and an average annual growth rate of 18%. With geopolitical factors driving supply chain localization, local manufacturers continue to make efforts in technology iteration and cost-effectiveness, while foreign brands focus on the iterative upgrading of ultra-pure process pumps.

In the semiconductor field, chemical pumps account for a considerable proportion. Anhui Shengshi Datang Group keenly seized this opportunity and actively participated in the exhibition to expand cooperation areas. Regarding our company's technological research in the semiconductor industry, the following processes are presented. In the front-end process, an ultra-high-purity PFA-lined fluorine magnetic pump is adapted for BOE etching solution transportation, with a temperature resistance range of -50°C to 180°C. In the middle-end process, a self-priming multi-stage centrifugal pump is matched with the exhaust condensate circulation of the EUV lithography machine. In the back-end process, a corrosion-resistant pneumatic diaphragm pump is used for adding electroplating solution to the ABF carrier board. At the same time, we have launched a "pump body lifecycle management" service, equipped with medium matching testing, and providing customized transformation plans to assist in the development of the semiconductor industry.

In modern industrial pipeline systems, flanges (Flange) play a crucial role as an indispensable connecting component. Whether in industries such as petrochemicals, electric power, water supply and drainage, or pharmaceuticals, as long as there is pipeline transportation involved, flanges are everywhere.

 

 

Anhui Shengshi Datang Chemical Equipment Group Co., Ltd. widely uses stainless steel flanges as key connecting components in the field of pump product manufacturing. The enterprise strictly follows the GB standard system for the flange products it uses, covering various models such as 304, 316, 316L, 321, and duplex steel 2205. Through precise material selection and standardized production processes, it ensures the corrosion resistance, high-temperature pressure-bearing performance, and long-term reliability of equipment in the chemical field.

 

 I. Flange Connection Structure

A flange is usually disc-shaped, with bolt holes around the periphery and a hole in the middle through which the pipeline or equipment passes. During installation, two flanges are placed opposite each other, a gasket is placed in the middle, and then bolts are passed through the bolt holes and tightened, thus tightly connecting the pipelines or equipment to ensure that the medium in the pipeline does not leak. At the same time, it can also provide certain support and positioning functions for the pipeline system.

 

 

The selection of different materials is based on factors such as the characteristics of the medium in the pipeline, working pressure, and temperature. For example, stainless steel flanges are often selected for chemical pipelines transporting highly corrosive media; while carbon steel flanges can meet the requirements in ordinary water pipeline systems.

 

 II. Types of Flanges

Common pipeline flanges include flat welded flanges, butt welded flanges, socket welded flanges, loose flanges, and threaded flanges.

 

 III. Flange Sealing Surface Forms

Flange sealing surfaces are divided into flat face, raised face, male and female face, tongue and groove face, and ring joint face.

• Flat Face (FF): The sealing surface is a smooth plane, suitable for occasions with low pressure and non-toxic media, generally used for connections in water pipelines and other less demanding applications.

 

 

• Raised Face (RF): Also known as a flat sealing flange, the sealing surface is a plane. It has a relatively large contact area with the gasket. After pre-tightening, the gasket is prone to stretching or moving to both sides, resulting in poor sealing performance, and is only suitable for low-pressure occasions.

 

 

• Male and Female Face (MFM): Composed of a male face and a female face, they need to be used in pairs during installation. This sealing performance is better than that of flat flanges and is commonly used for pipeline connections of medium-pressure, toxic and harmful media.

• Tongue and Groove Face (TG): The sealing surface consists of a tongue and a groove. The sealing performance is very good and is generally used for the connection of pipelines with flammable, explosive, toxic media and high pressure.

• Ring Joint Face (RJ): A ring-shaped trapezoidal groove is machined on the raised surface of the flange as the sealing surface of the flange. Similar to the tongue and groove face, the flange must be separated axially during installation and disassembly. The possibility of axial separation of the flange must be considered in pipeline design. This type of sealing surface is specially used in conjunction with solid metal gaskets processed into octagonal or elliptical shapes from metal materials to achieve a sealed connection. It has good sealing performance, strict requirements on installation, is suitable for high-temperature and high-pressure working conditions, but requires high precision in gasket processing.

 

 IV. Flange Markings

The following main information is usually provided on the outer ring or near the sealing surface of a flange:

 

 

• Nominal Diameter (DN): Indicates the diameter of the pipeline connected by the flange. The unit is usually millimeters (mm). For example, "DN100" means that the flange is suitable for pipelines with a nominal diameter of 100 mm.

• Nominal Pressure (PN): Represents the design pressure that the flange can withstand. The commonly used units are megapascals (MPa) or pounds per square inch (psi). For example, "PN16" means that the nominal pressure of the flange is 16 bar.

American Standard flanges use the CLASS marking. For example, "CLASS 150" indicates that its pressure rating is 150 pounds.

• Material Code: The material of the flange determines its strength, corrosion resistance, and applicable environment. Common material codes include:

    ◦ Carbon Steel: For example, "A105" represents forged carbon steel.

    ◦ Stainless Steel: For example, "304" or "316" represent different types of stainless steel.

    ◦ Alloy Steel: For example, "F22" represents low-alloy steel.

• Standard Code: The design and manufacture of flanges must comply with specific standards, such as:

    ◦ ANSI/ASME B16.5: American Standard flange.

    ◦ EN 1092-1: European Standard flange.

    ◦ GB/T 9119: Chinese National Standard flange.

• Heat Treatment Status: Some flanges are marked with heat treatment processes, such as "N" (Normalized) or "QT" (Quenched and Tempered).

 

 V. Flange Standards and Sizes

The flange standard system is divided into American and European standard systems. The pairing size of flanges (the sealing surface and bolt connection sizes of flanges, as shown in the box in the figure) must be completely consistent to ensure reliable connection and sealing of flanges. Obviously, flanges of different standard series and pressure levels basically cannot be paired. Even if there are exceptions, the scope of exceptions is very small, and generally, this is not done in engineering.

 

 

Sometimes, pipelines with inconsistent connection sizes cannot be connected, especially for pipelines where the sizes of metric pipes and imperial pipes differ significantly.

High-viscosity fluids, with their inherent resistance to flow, present a formidable challenge for traditional pump systems.   

These thick, sluggish materials strain conventional designs, leading to a range of operational inefficiencies.   Below are the most common issues faced during high-viscosity transfer:

Inefficient Flow Rates

Centrifugal pumps, reliant on kinetic energy, lose effectiveness with thicker fluids.    

Their impellers cannot generate sufficient force to move viscous materials smoothly, resulting in sluggish flow or complete failure.

Cavitation and Blockages

High resistance in pipes and valves increases the risk of cavitation (vapor bubbles collapsing) and clogs.    

Gear pumps or other positive displacement pumps may overheat or jam due to inadequate clearance for dense fluids.

Shear Sensitivity

Many viscous materials (e.g., creams, polymers) degrade when subjected to high shear forces.    

Screw or piston pumps, which rely on aggressive mechanical action, can damage product integrity.

High Energy Consumption

Thick fluids demand more power to move.    

Inefficient pumps waste energy, driving up operational costs.

Maintenance Burden

Wear and tear from abrasive viscous materials shorten pump lifespan.    

Frequent part replacements or cleanouts disrupt workflows.

Why Rotary Lobe Pumps Are the Ideal Solution

Rotary lobe pumps, engineered for precision and reliability, are built to tackle high-viscosity challenges head-on.    

Here’s how they outperform conventional options:

1.Gentle, Low-Shear Handling

Rotary lobe pumps use synchronized rotating lobes that create a smooth, continuous flow without pulsing or turbulence.    

This gentle motion preserves the structure of shear-sensitive materials like cosmetics, sauces, or pharmaceutical slurries, ensuring product quality.

2.Exceptional Self-Priming and Suction Capability

Unlike centrifugal pumps, rotary lobe pumps excel at self-priming, even with highly viscous or semi-solid substances.    

Their tight internal clearances prevent air ingress, enabling reliable suction without cavitation.

3.High Efficiency with Minimal Energy Use

The positive displacement design ensures consistent flow rates regardless of viscosity.    

This reduces energy waste, as the pump only uses the power required to move the material—no more, no less.

4.Clog-Resistant Design

Rotary lobe pumps feature large, open flow paths and fewer internal obstructions.    

Combined with reversible operation, this minimizes clogging risks and allows easy clearing of blockages without disassembly.

5.Durability in Demanding Conditions

Constructed from hardened metals or food-grade stainless steel, rotary lobe pumps withstand abrasive or corrosive materials.    

Their robust sealing systems and easy-access components simplify maintenance, extending service life.

6.Versatility Across Applications

From pumping chocolate at 10,000 cP to transferring asphalt at 500,000 cP, rotary lobe pumps adapt seamlessly.    

They handle suspended solids, variable temperatures, and non-Newtonian fluids with ease.

Real-World Applications
Food & Beverage: Transferring honey, peanut butter, or dough without damaging textures.

Chemicals: Moving resins, adhesives, or lubricants efficiently.

Wastewater: Handling sludge and grease-laden fluids.

Pharma: Precise dosing of high-viscosity gels or ointments.

Conclusion

When traditional pumps falter under the strain of high-viscosity materials, rotary lobe pumps deliver reliability, efficiency, and precision.    

By minimizing shear, reducing downtime, and cutting energy costs, they empower industries to optimize their processes and protect product integrity.

More details please click high viscosity liquid pump.

What is viscosity?

The viscosity of a fluid can be regarded as a measure of how resistive the fluid is to flow, it is comparable to the friction of solid bodies and causes a retarding force. This retarding force transforms the kinetic energy of the fluid into thermal energy.

The ease with which a fluid pours is an indication of its viscosity. For example, cold oil has a high viscosity and pours very slowly, whereas water has a relatively low viscosity and pours quite readily. High viscosity fluids require greater shearing forces than low viscosity fluids at a given shear rate. It follows therefore that viscosity affects the magnitude of energy loss in a flowing fluid.

Below table is reference viscosity for normal liquids.

What liquid need a pump with heating jacket during transferring?

When transferring high viscosity liquids, such as resin, polyurethane, polymer, polyethylene, detergent, glue, sugar, chocolate and other liquids that are solidifying at room temperature. Liquid that flows easily by heating, and places that need to be insulated for outdoor installation in alpine regions.

What is the role of the heating jacket?

Most high viscosity liquids will decrease in viscosity with increasing temperature during heating, increased mobility for easy transfer. When the pump starts working in the cold region, or stop for some time, the first warm-up reduces the starting power of the pump and not damages the motor.

How does Bonve rotary lobe pump with heating jacket work?

Bonve rotary lobe pump heating jacket is built in pump chamber or pump cover. Heating medium keeps a circulation work in the jacket, and heat the transferred product. This way can make product flow more easily, so achieve efficient transfer. Heating mediums can be conduction oil, steam or hot water according to the site's conditions.
