Bottling of liquid fertilizers with Pomac centrifugal pumps

Production and use of liquid mineral fertilizer

Already since 3100 BC, organic fertilizer is used: animal feces and other agricultural waste are applied to the fields. Today, this type of fertilization often is no longer sufficient to compensate the removal of nutrients from the ground which is caused by harvesting. By use of mineral fertilizers, the need of nutrients of the plants can be covered completely.

In mineral fertilizers, usually the active ingredients are contained in form of salts. When nitrogen, phosphate and potassium are included, it is called “complete fertilizer”. Aside from these essential nutrients, often magnesium, calcium and sulphur are admixed to some mineral fertilizers.

In the production of the fertilizer, the Pomac centrifugal pumps are applied only after the mixture of the different ingredients: They convey the mixture to the filling station, where the fertilizer finally gets into its bottles. Pomac centrifugal pumps of type CPC are perfectly suited for this task because of their optimal hydraulic conditions for fluids with low viscosity.
