Solution
Advantages of Pomac centrifugal pumps, type CPC:
- Conveying of fertilizers from the mixing unit to the bottling unit under optimal hydraulic conditions for fluids with low viscosity
- Dry-run safe because of the flushed double shaft seal out of silicon carbide according to DIN 24960
- Long service life of the centrifugal pumps
- Protection against corrosion with high-level 1.4404 stainless steel (316L)
- Modular construction of the pump: easy maintenance and repair
- Removable seals
- Construction according to criteria of the EHEDG
- Roughness of wetted parts < 0.8 μm
- Open impellers with pressure relief bore holes, which reduce the axial pressure and enable optimal cleaning
- Resistant to bigger variations of temperature (CIP/SIP)
- Numerous possibilities for shaft sealing
- Wide selection of connections
Background
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.
