Re: Is my motor the appropriate size for the mixing intensity I need?30 August 2010 at 1:29pm
You failed to provide a critical piece of information regarding the type of impeller. However, as expected, running a small impeller 140 mm in diameter, at only 200 rpm, the power requirements for any type impeller are less than 0.02 hp. A 1/2 hp motor is more than adequate, even a 1/4 hp motor is sufficient. The mixing intensity will be gentle, but should be adequate to move the entire contents and avoid excessive splashing. Since I doubt that the tank will have baffles, you will get a considerable amount of swirling and probably a strong vortex on the surface. These conditions would not be good for mixing a larger quantity of material, but you have a small volume which will mix quickly.
