Dip Tank Agitation for the Automotive Industry

In order to keep large volumes of water, paints or chemicals moving in applications such as dip tanks, the use of eductors is an ideal solution.

Eductor nozzles provide an effective and economical way to circulate and mix liquids in both open and closed tanks. These eductors have no moving parts, are clog-resistant and require little or no maintenance. The eductor nozzles will reduce settling of suspended solids, improve circulation, maintain uniform liquid characteristics, mix chemicals, or move solids along the bottom of the tank. This nozzle offers a light-weight, inexpensive alternative to mechanical mixing methods.

The operation of the eductor nozzle creates a multiplying effect on the fluid flow. Depending on the model and operating pressure, the volume of the liquid discharged from these nozzles can be four or five greater than the fluid pumped.

With regards to the positioning for eductor nozzles: in order to agitate liquids or fluids with suspended solids, position the eductor nozzle at the bottom of one side of the tank and direct the plume upwards towards the opposite side of the tank, aiming at the highest likely liquid level.

If you need to sweep solids along the bottom of the tank, direct the eductor plume downward at a 10 or 20-degree angle, using a sufficient number of units to cover the bottom surface of the tanks.

Optimisation tips:

Be sure to use the best type of eductor nozzle for your application and implement a regular maintenance program
Monitor flow rate and pressure to detect wear to the orifice
