- Key Products/Technologies
- Magnet Pumps transfer fluid by transmitting motor rotation force through magnetic power to the impeller. The seal-less design prevents leakage and fluid contamination, ensuring easy maintenance. This makes them ideal for applications in chemical processing, pharmaceutical production, and semiconductor manufacturing where leak-free operation is critical. The product line includes External Magnet Pumps, Rotary Magnet Pumps, Vane Magnet Pumps, and Wesco Magnet Pumps. Models such as MD-EPB-3, MD-EPA-12, and MD-MKA-25 are part of their offerings.Magnet Pumps transfer fluid by transmitting motor rotation force through magnetic power to the impeller.

- Rotary Gear Pumps are positive displacement pumps that transfer liquid through the meshing of two gears. They offer excellent volumetric efficiency and can handle all types of flowing liquids, from low to high viscosity. These pumps operate across a wide temperature range from -50℃ to +350℃ and viscosity range from 0.1cps to 500,000cps. The SW Series features excellent self-priming capability and smooth, pulsation-free fluid transfer. The SW-H Series is an upgraded design, manufactured in accordance with API610 regulations, optimized for special conditions such as high viscosity, high temperature, high pressure, and continuous operation. Models like SWD-F50 (6㎥/hr × 7.0㎏/㎠) and SWA-F50 (1.44㎥/hr × 3.0㎏/㎠) are available.Rotary Gear Pumps are positive displacement pumps that transfer liquid through the meshing of two gears.

- Self-Priming Pumps possess superior self-priming capabilities, allowing them to draw fluid using only the liquid inside the pump casing after initial operation, without the need for a foot valve. Their compact and lightweight design facilitates easy relocation. A wide selection of materials is available to suit various acidic and alkaline fluids.Self-Priming Pumps possess superior self-priming capabilities, allowing them to draw fluid using only the liquid inside the pump casing after initial operation, without the need for a foot valve. Their compact and lightweight design facilitates easy relocation. A wide selection of materials is available to suit various acidic and alkaline fluids.
- High-Pressure Wesco Pumps operate on the principle of cutting double vanes on the outer circumference of the impeller, causing fluid to rotate along grooves inside the casing, increasing pressure and discharging the fluid. This solution is effective for applications requiring high head with low flow rates. They offer a maximum capacity of 7㎥/Hr, maximum differential pressure of 12㎏/㎠, maximum temperature of 120℃.High-Pressure Wesco Pumps operate on the principle of cutting double vanes on the outer circumference of the impeller, causing fluid to rotate along grooves inside the casing, increasing pressure and discharging the fluid.

- Rotary Vane Pumps are positive displacement rotary pumps, also known as Sliding Vane Pumps. They combine the volumetric advantages of gear pumps with improved wear resistance and quiet operation. Their excellent suction capability eliminates the need for a foot valve at the bottom of the suction pipe. These pumps are particularly well-suited for solvent transfer. Models such as VTB-50 (9㎥/hr × 18㎏/㎠) are provided.Rotary Vane Pumps are positive displacement rotary pumps, also known as Sliding Vane Pumps.
