Founded in 1989 and headquartered in Jiangyin, Jiangsu Province, Keheng was formerly known as Jiangyin Petrochemical Electric Machinery Plant, boasting over 30 years of experience in manufacturing mixing equipment. The company is ISO 9001 quality management system certified, equipped with advanced processing and testing equipment (such as CNC lathes and pressure testing benches), and has established a research and development center to support the implementation of non-standard customized projects. Its products have been exported to countries and regions such as Germany, Australia, and the Middle East, and it has accumulated a large number of customer cases in the automotive painting and petrochemical industries.

1. Structural design
The Keheng vertical mixer adopts a top-insertion installation (i.e., the main shaft is vertically inserted into the top of the container). Its main components include a motor, reducer, main shaft, and mixing paddle. The equipment has a compact overall structure and supports a variable frequency speed control motor, allowing the speed to be dynamically adjusted according to the material viscosity and process requirements.
2.Material optimization
Key components (such as the agitator and spindle) are made of 316L stainless steel, which has excellent corrosion resistance and can withstand harsh media such as strong acids and alkalis. For example, the agitator customized for an automobile manufacturing company in Yemen successfully solved the corrosion problem in paint mixing through material upgrades.
3.Sealing system
The standard configuration features a single-end-face cartridge mechanical seal, effectively preventing liquid leakage and ensuring safe production. For high-pressure and high-temperature environments, Keheng also offers optional solutions such as dual mechanical seals or magnetic seals.
4.Hybrid performance
· Uniformity: By optimizing the impeller blade shape (e.g., propeller type, anchor type) and rotation speed, uniform mixing of materials throughout the entire volume can be achieved, avoiding color differences or stratification.
·High Efficiency: For high-viscosity fluids (such as asphalt and resin), a high-torque reducer and low-speed mixing technology are used to reduce energy consumption while improving mixing efficiency.
5.Reliability and Maintenance
Before leaving the factory, the equipment undergoes rigorous inspections, including no-load testing and pressure testing, to ensure smooth motor operation without abnormal vibration. The modular design facilitates quick replacement of vulnerable parts (such as seals and bearings), reducing downtime.
Chemical and petroleum industries: Used in processes such as polymerization, emulsification, and dispersion in reaction vessels, for example, in the stirring production of petroleum resins.
Food and beverage: Syrup preparation, dairy homogenization, sauce mixing, etc., equipment meets food-grade stainless steel requirements.
Wastewater treatment: Sludge in anaerobic tanks and equalization tanks is suspended and mixed with chemicals. For example, Nanjing Lanjiang Pump Industry's LHJ vertical circulating mixer adopts a large circulation flow scheme, which can cover water tanks with a depth of 2-9 meters.
Automotive painting: For example, a car factory in Yemen purchased 12 vertical mixers for paint mixing to ensure uniformity and stability of the coating.

Keheng vertical mixers have secured a place in both domestic and international markets thanks to their high cost-performance ratio and customized services. Their advantages include:
·Rapid Response: Short lead time from solution design to delivery; for example, a mixer customized for a Yemeni client was produced and accepted within two months.
·Full Lifecycle Service: Providing one-stop service including installation, commissioning, regular maintenance, and spare parts replacement, reducing customer operating costs.
·Industry Recognition: Customer feedback indicates the equipment operates stably and achieves mixing results superior to industry standards, particularly excelling in demanding scenarios such as automotive painting.
