Enhancing In-Tank Agitation with BETE TurboMix Eductor Nozzles

Achieving continuous, uniform fluid circulation and solid suspension inside process tanks has traditionally presented a costly engineering challenge. Conventional mechanical mixers and submerged high-volume pumps often require significant capital investment, ongoing
maintenance, and heavy power consumption.

The BETE TurboMix® Eductor Nozzle, supplied by Spray Nozzle Engineering, provides a lightweight, highly efficient, and low-maintenance alternative designed to streamline in-tank agitation across diverse industrial operations.

How the Venturi Principle Multiplies Flow Rate

The core advantage of the BETE TurboMix lies in its intelligent utilisation of fluid dynamics.

Operating completely submerged without any moving parts, the nozzle leverages the Bernoulli principle: as motive liquid is pumped through the nozzle, its velocity increases while its pressure drops.

This local low-pressure zone (the Venturi section) draws in surrounding tank liquid, combining it with the primary pump stream.

• 3–5x Flow Multiplication: The total volume of liquid exiting the discharge plume is 3 to 5 times greater than the motive fluid pumped into the nozzle.

• Lower Capital & Energy Costs: By multiplying circulation volume, facilities can achieve superior agitation using significantly smaller, lower-capacity pumps.

• Reduced Operating Downtime: Built with no mechanical moving components, the TurboMix is inherently clog-resistant and virtually maintenance-free.

Core Applications

Whether managing thermal consistency, preventing heavy particle settling, or accelerating chemical reactions, TurboMix eductor nozzles deliver versatile performance across key industries:

• Wastewater Treatment & Digesters: Keeps solids in suspension in aerobic and anaerobic digesters, preventing thermal stratification, sludge accumulation, and bacteria growth.

• Chemical & Fuel Blending: Ensures thorough homogenization during chemical dosing, ethanol/biodiesel blending, and liquid-phase reactions.

• Surface Treatment & Plating: Maintains uniform fluid concentration and temperature across phosphating, electrocoating, anodising, and plating baths.

• Food, Beverage & Agriculture: Facilitates open tank cooking of grains, mash, or starches via steam injection, as well as liquid fertiliser mixing.

Material Options & Temperature Ratings

To withstand demanding fluid chemical profiles and thermal demands, the TurboMix range is available in both molded polymers and high-grade metal alloys:

Placement and Engineering Guidelines

To maximise tank turnover and eliminate dead zones, placement geometry must match the target application:

1. General Liquid Agitation & Suspensions: Mount the eductor near the tank bottom on one side. Angle the plume upward toward the opposite wall, aiming at the highest liquid level to establish continuous recirculating currents.

2. Bottom Sediment Sweeping: Direct the nozzle plume downward across the tank floor at a 10°- 20° angle to sweep sludge and solids toward pump suction inlets.

3. Calculating Plume Reach: The approximate length of the discharge plume (in metres) equals the differential pressure in kPa divided by 23. When sweeping heavy solids along the bottom, reduce this estimated length by 50%.
