Re: Is my mixer size too large?19 February 2010 at 1:29pm
Your suggested mixer size is way too large for your tote. To mix 340 gallons of a 100 cp fluid with a 1 sp gr requires only about a 1/2 hp mixer at 350 rpm. A 350 rpm mixer with a 1/2 hp motor would normally be supplied with a 5-inch hydrofoil impeller. However, if a 45-deg pitched turbine were used (but not recommended), it would only be about 3.5 inches in diameter.
A 14-inch diameter pitched turbine would overload a 2-hp motor at 350 rpm. A 2-hp mixer with any impeller would be more mixing than you need in 340 gallons.
The answers by this expert are based on the best available interpretation of the information provided. The consequences of the application of this information are the responsibility of the user. If clarification is needed, please submit a further question.
Would a four-blade, 45-deg pitched, 14-inch diameter impeller be too large or about right to mix a square IBC - 340 gallons of sp gr = 1 and viscosity of up to 100 centipose liquid, turning at up to 350 rpm, 2 HP motor.
