Mixer... Gear versus direct
Mixer... Gear versus direct
(OP)
I have to size a mixer for a batch system. The fluid has a viscosity of 300-500 cp and the tank can contain 350 usgal. With my estimate, I would need a direct drive mixer with 2 hp. My supplier is recommanding a gear drive mixer with 3/4 hp. Hmmm... I have never used a mixer like that, but I would need to know why the efficiency is so different...
Thanks
Thanks

some impellers work better at lower speed with gear drive, others can work with a direct drive.
Depending in the detail data (geometry of the vessel, goal of the agitation etc.) you may have chosen a different impeller type than the supplier resulting in a different motor size.
