- Key Products/Technologies
- **Magnet Pumps (External Magnet Pump, Rotary Magnet Pump, Vane Magnet Pump, Wesco Magnet Pump)**: A pump type that transfers fluid by transmitting the rotational force of the motor to the impeller via magnetic force. Its seal-less (Non-Seal) structure prevents leakage and fluid contamination, ensuring easy maintenance. Suitable for applications where leak-free operation is critical, such as chemical processing, pharmaceutical production, and semiconductor manufacturing. Models include MD-EPB-3, MD-EPA-12, MD-EPA-4, MD-MKA-25, MD-SWB-40S, MD-SWA-40S, MD-SWA-80, MD-VTA-25, MD-DHWA-40.**Magnet Pumps (External Magnet Pump, Rotary Magnet Pump, Vane Magnet Pump, Wesco Magnet Pump)**: A pump type that transfers fluid by transmitting the rotational force of the motor to the impeller via magnetic force.

- **Self-Priming Pumps**: A type of centrifugal pump designed to automatically expel air or gas from the suction line without external priming, enabling suction of liquid from below the pump's level. The suction pipe is located above the impeller, and liquid is stored inside the pump to act as a priming fluid during restart. Eliminates the need for a foot valve, offering simple structure and easy disassembly/assembly.**Self-Priming Pumps**: A type of centrifugal pump designed to automatically expel air or gas from the suction line without external priming, enabling suction of liquid from below the pump's level.
