Silo cleaning pumps: everything you need to know


Silos are structures used to store powdered or granular materials, such as grains, minerals and chemicals. However, due to the nature of the materials stored, these structures can be subject to contamination and accumulation of residues. Thorough and frequent cleaning not only helps to maintain the quality of the stored materials, but also helps to prolong the life of the silos themselves, reducing the need for costly maintenance and repair.

Furthermore, keeping silos clean is an essential requirement to comply with safety and hygiene regulations, preventing potential penalties and ensuring a safe working environment for operators.

With this article, we at Hawk will take an overview of the most suitable pumps for this activity.

How to choose the right pump for silo cleaning

Choosing the right pump for silo cleaning requires careful consideration of several factors to ensure that the equipment is suitable for the specific needs of the application. Firstly, it is essential that the pump is made of materials that are compatible with aggressive fluids and chemicals, as cleaning processes are often carried out with strongly alkaline or acidic detergents, solvents and other corrosive substances. Materials such as 316L stainless steel or Ecobrass are particularly suitable, as they are designed to withstand corrosive chemicals without long-term problems.

In addition, it is essential to choose a pump that offers high pressure, which is essential to effectively remove debris and contaminants from the internal surfaces of the silo. Adequate pressure ensures thorough and fast cleaning, reducing downtime and improving operational efficiency.

Finally, the chosen pump must provide adequate capacity to maintain a constant and powerful flow throughout the entire cleaning process. A pump with insufficient capacity may not be able to perform effective cleaning, causing delays and potential operational problems.
