1. Tank-Specific Placement Strategies

Rectangular Tanks: The 1/3 Rule

In long tanks, the goal is longitudinal circulation. Place the mixer at the 1/3 or 1/4 mark of the length, offset toward one side wall. Aim the jet toward the opposite diagonal corner with a 5°–10° downward tilt. If the tank exceeds 25 meters, two mixers are required to maintain momentum.

Square Tanks: Breaking Symmetry

Square tanks often suffer from "dead centers." Install a single mixer offset from the center of one wall to create an eccentric vortex. For dual installations, use a diagonal layout to form a powerful unified circular force.

Circular Tanks: Tangential Flow

Always install the mixer tangentially along the curve of the wall. Never point it directly at the center, as this creates a stagnant core and poor mixing efficiency.

2. Universal Installation Rules

● Avoid Obstructions: Keep mixers away from pillars, pipes, and inlet/outlet zones to prevent "shadow zones."

● Clear the Floor: Ensure the impeller is not too close to the bottom to avoid sand burial or damage to the mechanical seals.

● Flow Direction: If using multiple units, ensure they work in the same direction (clockwise or counter-clockwise) to avoid energy cancellation.
