KG
The KG series coaxial vortex pump is a specialized industrial pump engineered specifically for reliable circulation of plating solutions and other corrosive liquids in precision manufacturing processes. Utilizing advanced coaxial vortex technology, this pump delivers smooth, pulsation-free liquid flow with excellent self-venting capabilities, making it ideal for continuous plating liquid circulation applications. Constructed from high-quality corrosion-resistant materials including CFRPP, CPVC, and PVDF, the KG vortex pump offers exceptional durability and chemical compatibility across a wide range of industrial environments. With its compact design and efficient performance, this pump is the preferred choice for plating shops and chemical processing facilities worldwide.
Equipped with an integrated exhaust valve that automatically removes air from the pump and pipeline during operation, preventing air lock and shaft seal damage caused by excessive air intake. This feature ensures uninterrupted operation even in systems with intermittent air entrainment.
The coaxial vortex impeller design produces low-shear liquid flow, minimizing damage to sensitive plating solutions and ensuring consistent plating quality. This gentle flow characteristic is critical for maintaining the integrity of precious metal plating baths and chemical solutions.
Available in CFRPP, CPVC, and PVDF materials to handle various acids, alkalis, and chemical solutions at temperatures up to 90°C. All wetted components are designed to resist chemical attack and provide long service life in corrosive environments.
Modular construction with a small footprint allows for easy installation in tight spaces and integration into existing production lines. The pump can be quickly disassembled for maintenance without disrupting the entire system.

The exhaust valve automatically removes air from the pump and pipeline during operation, preventing air lock and shaft seal damage caused by excessive air intake, which is crucial for continuous and reliable operation in plating systems.
The KG series pump has no self-priming capability and must be installed below the liquid level. A foot valve should be installed at the inlet to prevent foreign objects from entering, and a check valve should be installed at the outlet to prevent backflow when the pump stops.
Yes, the maximum operating temperature is 75°C for CFRPP, 80°C for CPVC, and 90°C for PVDF materials. For higher temperature applications, please contact our technical team for customized solutions.
