FAQ

1. Leakage Issues (Most Common)

– Static sealing surface leakage: Check if the stationary ring seals (O-rings, V-rings) are aged, deformed, or missized. Replace with seals of the same specifications that are resistant to the medium and temperature. If the clearance between the stationary ring and the gland is too large, the stationary ring needs to be re-machined or replaced.

– Dynamic sealing surface leakage: Check the sealing end faces of the dynamic and stationary rings for scratches, wear, or chipping. Minor scratches can be repaired by grinding; for severe scratches, replace the sealing ring directly. Also, confirm if the spring compression is appropriate. If insufficient compression, add gaskets; if excessive compression, reduce the number of gaskets.

– Leakage at the bushing-shaft mating point: Check if the bushing seal is damaged or if the clearance between the bushing and the shaft is too large. Replace the seal or re-grind the bushing.

2. Abnormal Wear

– Excessive end face wear: If due to particulate impurities in the medium, a filter needs to be installed; if due to insufficient lubrication, a self-lubricating seal such as an impregnated graphite ring can be used, or an external flushing fluid (such as a clean liquid of the same medium) can be introduced.

– Shaft sleeve wear: Replace the shaft sleeve with one made of wear-resistant material, and adjust the coaxiality of the sealing cavity and the shaft to avoid uneven wear.

3. Overheating and Burnout

– Excessive sealing cavity temperature: Check for blockages in the cooling system and clean the cooling pipes; if the medium temperature itself is too high, use high-temperature resistant sealing materials (such as silicon nitride ceramic rings or fluororubber sealing rings).

– Spring failure leading to poor end-face contact: Replace fatigued or corroded springs with corrosion-resistant spring materials such as stainless steel, and ensure uniform spring compression.

4. Vibration and Abnormal Noise

– Coaxiality Deviation: Recalibrate the coaxiality of the pump shaft and motor shaft, adjust the radial runout of the sealing cavity and shaft, and control it within the allowable range.

– Loose Parts: Check whether the gland bolts and drive pins are loose, tighten the bolts evenly according to the specified torque, and replace worn drive pins.

5. Short lifespan of the seal

– Material mismatch with the medium: Replace the sealing material according to the characteristics of the medium (e.g., use Hastelloy or PTFE for corrosive media; use silicon carbide for high-temperature media).

– Improper installation: Strictly follow the installation specifications to avoid impact or scratches on the sealing surface, and ensure that no impurities enter the sealing cavity during installation.

Kunshan Xinyoumi Mechanical Seal Technology Participated in Jinan Fermentation Exhibition 2026 | March 9

On March 9, 2026, Kunshan Xinyoumi Mechanical Seal Technology Co., Ltd., a leading manufacturer of mechanical seals for fermentation industry, officially participated in the well-known Jinan Fermentation Exhibition held in Jinan, Shandong Province. As a professional enterprise focusing on R&D, production and sales of industrial mechanical seals, Xinyoumi brought its full range of fermentation tank mechanical seals, agitator mechanical seals and customized sealing solutions to this top biofermentation industry event, demonstrating its professional strength in fluid sealing technology for fermentation equipment to global buyers and industry partners. Overview of Jinan International Biofermentation Exhibition 2026 The Jinan Fermentation Exhibition is one of the most influential professional exhibitions in the global biofermentation, biopharmaceutical and food fermentation industries, focusing on cutting-edge technologies, equipment and supporting products for the entire fermentation industry chain. This exhibition gathered hundreds of enterprises from home and abroad, covering fermentation raw materials, production equipment, environmental protection technology and supporting sealing accessories, attracting professional visitors, procurement teams and technical experts from fermentation plants, pharmaceutical factories, food processing enterprises and engineering companies worldwide. It has become a key platform for technical exchanges, business cooperation and market expansion in the fermentation equipment field, and a must-visit exhibition for mechanical seal suppliers to connect with target customers in the fermentation industry. Xinyoumi’s Featured Mechanical Seals for Fermentation Industry Exhibited At the exhibition booth, Kunshan Xinyoumi focused on displaying a series of high-performance mechanical seals specially designed for fermentation tanks and mixing kettles, which are tailor-made for the special working conditions of the fermentation industry such as corrosion resistance, sanitation level, high temperature and low leakage. The core exhibits include: 1. Sanitary Grade Fermentation Tank Mechanical Seals: Comply with GMP and FDA standards, made of food-grade and corrosion-resistant materials, suitable for sterile fermentation production in food, beverage and biopharmaceutical industries, effectively preventing material leakage and external pollution, and meeting the strict hygiene requirements of the fermentation industry. 2. Agitator Shaft Mechanical Seals for Fermentation: With unique dynamic balance design and wear-resistant sealing end faces, it adapts to the long-term operation of fermentation agitators, has excellent anti-wear and anti-corrosion performance, reduces maintenance frequency, and extends the service life of fermentation equipment. 3. Customized Industrial Mechanical Seals: Provide personalized sealing solutions for special specification fermentation equipment, solving the sealing pain points of non-standard equipment in small and medium-sized fermentation enterprises, and realizing zero leakage and stable operation of production equipment. Our professional technical team conducted in-depth communication with every visiting customer on site, introduced the technical advantages, application cases and after-sales service of fermentation equipment mechanical seals in detail, and answered technical questions about sealing selection, installation and maintenance for customers in the fermentation industry.
