The Effects of Impeller Diameter | Sepro Mixing

Not having the right impeller diameter is a common cause of agitator failure. In our latest video, we put 3 different impeller diameters to the test to see which is best at successfully suspending solids!

A very interesting demonstration. I would like to see what happens when the oversize impeller is operated in the opposite direction. i.e. Up-flow, rather than down-flow

Distances of impellers from bottom must be considered

i love u i have been finding a solution for an hour straight

Thank you for very useful video! But what's about liquid emulsions? Or about solid particles that are less dense, than water medium?

Why are they placed with different distance to the floor? I mean, if you shuv number 1 down at the same level as number 4, wouldnt that affect the results dramatically?

There is a large impeller spacing from reactor bottom..

Could you explain how did you get the power draw? Speed x Diameter, ejm. 73mm x 1070 rpm = 3.71 W ?

Whats the effects if Tank is a Square Plan Shape (Instead of Circular)

Thí nghiệm này sai, khoảng cách từ cánh khuấy tới đáy bể phải giống nhau thì chúng ta mới có thể so sánh. Ở bình thứ 3 và 4, khoảng cách là quá xa. Trong các thiết kế bồn chuyên nghiệp, tỉ lệ là 0.3. Với tỉ lệ 0.4 chúng ta sẽ phải chọn Motor gấp 5 lần công suất.
