What capacity suit for this bottom homogenizer mixer?

The capacity range of our homogenizer emulsifier mixer covers from 2L-1500L. For the upper homogenizer mixer, the drive motor is installed above the cover. If we need to open the tank, we need to lift the homogenizer motor together. For the capacity lower than 200L, most customers would choose the upper homogenizing mixer. The motor for lower capacity is not very heavy compare to the big capacity. Even the motor equip in the cover , it could also lift freely .  While for the capacity above 500L, especially the whole machine does not contain lift function  most customers would choose the bottom homogenizer one. On one hand, it’s cost safe design, and for another hand, it’s easy to maintain and clean.
