Frequently Asked Questions
How do I select the right model of Low Speed Mixer?
Selection depends on your required thrust (N), tank dimensions, and liquid density. Refer to the Low Speed Mixer Performance Parameters table to match the motor power (kW), speed (r/min), and propeller diameter to your application needs.
What does the "Mixing range speed of 0.1m/s (clear water)" mean?
This represents the boundary limit velocity profile of the mixer flow field in clear water. A velocity of 0.1m/s is generally the standard benchmark speed required to prevent solids settlement and maintain uniform mixing in municipal wastewater applications.
What is the difference between Submersible Mixers and Low Speed Mixers?
Submersible Mixers (QJB series) typically operate at higher rotational speeds (740 to 980 r/min) with smaller vane diameters (220 to 400 mm) for localized high-shear mixing. Low Speed Mixers (JUNTAIMIXER series) run at lower speeds (420 r/min) with larger diameters (up to 800 mm) to generate higher volumetric flow and thrust.
Why are the rated current values important for installation?
Rated current (A) determines the electrical cable sizing, overload protection settings, and control panel configuration. Ensuring your electrical system matches the rated current of the selected mixer model prevents motor burnout and electrical faults.
How does the number of electrodes affect mixer performance?
The number of electrodes (poles) determines the synchronous speed of the motor. For instance, 6-pole and 8-pole motors run at lower speeds compared to 2-pole or 4-pole motors, providing the necessary torque profiles required to drive larger mixing vanes efficiently.
