Key Data: Performance Specifications of Keheng top entry Mixers
I.Durability data: Adaptability to extreme environments
• Material Resistance: The 316L stainless steel agitator shaft showed no rust after 480 hours of salt spray testing; in a Vietnamese paper mill, the blade wear was only 0.15 mm after 3 years of use.
• Sealing Performance: The single-end face cartridge seal showed a cumulative leakage of < 2 ml over 3 years at 1.2 MPa pressure; 12 units in a Yemeni automobile factory operated for 1 year with zero leakage.
• Temperature Adaptability: In a -18℃ chemical project in Northeast China, the spindle speed fluctuation was ≤ 1.8 rpm after 30 days of continuous operation; in a 180℃ asphalt mixing scenario, the motor temperature remained stable at 62℃ (below the 75℃ safety limit).
II. Energy Consumption and Cost Data: The Economic Value of High-Efficiency Configuration
• Energy Saving of Motors: Equipped with an IE3 high-efficiency motor (SEW/WEG brand optional), the 15kW model operates for 8 hours a day, with an annual electricity cost of 35,040 yuan, saving 22% (8,000 yuan) compared to ordinary equipment in the industry, equivalent to the electricity cost of 8 household energy-saving refrigerators for 5 years;
• Maintenance Costs: Modular design of vulnerable parts, sealed replacement takes only 20 minutes, saving 70% of the time compared to traditional structures; bearings use national standard models, reducing procurement costs by 60%.

Brand Evolution: Keheng's 35-Year Journey of Mixing Technology Innovation
Brand Evolution: Keheng's 35-Year Journey of Mixing Technology Innovation
Keheng's development of top entry mixers has always resonated with industrial needs, marking a clear trajectory of technological breakthroughs:
① 1989-1995: Initial Foundation Stage Keheng's predecessor, Jiangyin Petrochemical Electric Machinery Plant, was established, focusing on the mixing needs of the petrochemical industry. Early vertical mixers used a combination of cast iron and ordinary steel, providing basic mixing equipment for small chemical plants in China—although it took 2.5 hours to mix 1 ton of raw material with a uniformity of 75%, the cost was 40% lower than imported equipment at the time, quickly opening up the market.
② 1996-2005: Material Upgrade Stage With the increasing corrosive conditions in chemical processes, Keheng pioneered the introduction of 304/316 stainless steel to replace ordinary steel, improving corrosion resistance by 3 times; equipped with imported motors from SEW, ABB, etc., the mixing time for 1 ton of material was shortened to 1.2 hours, increasing efficiency by 52% compared to the first generation. During this phase, acid-resistant agitators were customized for over 120 electroplating plants in the Yangtze River Delta region, reducing the sealing leakage rate from the industry average of 5% to 1.2%.
③ 2006-2015: Technological Breakthrough Phase
A 300,000-square-meter production base was established, overcoming the design challenges of rigid drive shafts and specialized impellers. A single-end-face cartridge mechanical seal system was launched: the 316L stainless steel agitator shaft exhibited a corrosion rate of only 0.02 mm/year in 5% chromic acid wastewater, with a sealing leakage rate ≤0.01 ml/hour, extending the lifespan from the industry average of 3 years to 8 years, and obtaining ISO 9001 quality management system certification.
④ 2016-Present: Intelligent Customization Phase
A variable frequency speed control and vibration monitoring system was developed, achieving adaptability to extreme operating conditions from -20℃ to 180℃; the customization response time was reduced from 7 days to 48 hours, allowing for precise matching of impeller type, shaft length, and sealing method according to requirements. Currently, it has 12 spare parts warehouses nationwide, serving 10 major industries including chemical, automotive, and paper manufacturing, and exports more than 500 sets of equipment annually.
