泵開始運轉時, 底部葉輪將液體逐步上推, 待液體進入
上部葉輪時, 即受加大之背葉的強大阻力而無法上升, 但上部葉輪所捲入液體中的空氣, 卻受阻於水室中貯滿的液體而無法下降, 如此巧妙地排除了立式無軸封泵高壓時溢流, 或大流量時吸入空氣的兩大難題.

這種**性的創新即將引導世界的立式泵產業進入嶄新的世代.

When pump starts, the lower impeller lifts the solution up step by step. And the extreme centrifugal force from the enlarged higher impeller stops the solution as it entering the higher impellr. At the same time, the full solution in the chamber stops the air mixed with the solution in the chamber to go down. This way masterly eliminates both big problems of vertical sealless pump, overflow at high pressure and bubbles at big flow.

This innovation will guide the vertical pump industries in the world into a brand-new generation.
