A chemical manufacturer came to Admix for a solution to remedy problems with corrosion and leakage on their current agitators.
The Problem: The customer works with 180 m3 tanks containing a solution of 30% sodium chloride and further 1% suspended solids, the tank temperature is 70°C. The existing side mounted agitators were not powerful enough and hence unable to keep the solids suspended in the tanks, and even worse the agitators/seal plate were leaking due to the harsh environment.
The Solution: Admix delivered a side mounted Rotofoil with all product contacting parts made in Titanium grade 2. This four bladed Rotofoil has a diameter at 787 mm with detachable blades for easy installation and is equipped with a 3 kW geared motor. Admix designed the agitator and agitator mounting to ensure that the solids would be kept suspended in the customer tank.
The payoff: The Admix Rotofoil now keeps all solids suspended, and there is no longer any issue with sediment on the tank bottom. The Titanium propeller, shaft, and double mechanical seal have solved the leaking issue. Thanks to the design and selection of materials, the customer has reduced maintenance costs significantly. The customer is happy and continues to use the Admix solution by replacing agitators in existing tanks with Admix Rotofoils.
Should you have issues with corrosion of your agitators, Admix can help with top or side mounted agitators all prepared for your specific liquids – with PTFE coating, made of Titanium grade 2 or Duplex steel whatever is the best for the application.
