Differences Between Submersible Mixers and Submersible Propellers

1. Core Functionality Differences

Submersible Mixer: Primarily designed for “mixing.” Generates a powerful jet stream through high-speed rotation, thoroughly and vigorously blending liquids and solid particles to prevent sedimentation.

Submersible Propeller Mixer: Primarily designed for “propelling flow.” Produces a large-volume, gentle water current via low-speed rotation. Its main function is to create a specific flow velocity, enabling directed water movement to maintain activated sludge suspension.

2. Different Impeller Shapes and Flow Velocities

Submersible Mixer: Typically features a propeller-type impeller with high rotational speed, generating fast-moving water currents but with a narrow flow field.

Submersible Pusher: Typically features a banana-shaped (swept-back) impeller with low rotational speed, producing slower water currents but with a wide coverage area and a flat flow field.

3. Different Primary Application Scenarios

Submersible Mixer: Commonly used in applications requiring vigorous mixing, such as sewage tanks, coagulation tanks, and neutralization tanks. Particularly suitable for conditions with high suspended solids concentration where uniformity must be maintained.

Submersible Pusher: Primarily used in large tanks like oxidation ditches and anaerobic/aerobic tanks. Its function is to slowly circulate water flow, ensuring sufficient contact and reaction time between microorganisms and wastewater.
