Closed impeller
Between both sides of the impeller are flat, flat with 4 ~ 6 leaves. When the blade bending direction with the impeller rotating in opposite directions, known as shield curved blade. After general impeller blades are curved blade. The closed impeller efficiency is higher, the most widely used.
Open impeller
On both sides of the impeller were not cover plate, blade through reinforcing plate connected to the hub. The impeller structure is simple, easy to make, but the efficiency is low, suitable transmission contains more suspended solid or liquid with a fiber.
