Side entry tank mixers and agitators are standard equipment for the Tank Process.   We will customize a side mount agitator to suit your needs and specifications.  Common agitator designs include cGMP sanitary design with FDA/USP VI elastomers in the seal, all stainless steel motors/gearboxes, small and large scale blending.

Gear drive side entry mixers are available in 1/4 – 100HP (3 to 350 RPM range, and high-speed designs for more shear available) to accommodate batch blend sizes from 50 to 1,000,000 gallons.


Oil & Gas

When crude oil is produced, it’s accompanied by sand, salt and other unwanted debris.

Until the crude is delivered to the refinery, bottom sludge & water (BS&W) can settle on the bottom of a tank.  ProMixUSA Mixing’s Side Entry Mixer keeps BS&W in suspension by generating the right fluid velocity distribution to provide the highest and most efficient performance.

The side-entry mixer concept is driven by four top priorities:  safety, reliability, process optimization, and easy, cost-effective maintenance.

  • Large mixing volumes.  The mixer is designed for tanks up to 200,000 m³ (1.3 MM barrels).  The high liquid jet amplitude propelled by our impeller allows the moving of large volumes using less power.
  • Easy installation and maintenance.  This compact, side-entry mixer has been designed specifically to mount on the lateral flange of the tank and with lightweight, custom impellers, it can be installed quickly and easily. Its exclusive seal shut off device allows for safe, fast, and easy maintenance or replacement of the mechanical seal without emptying the tank.
  • Low power consumption.  Our innovative, proven impellers uses less energy to effectively mix the tank contents.
