Fertilizer pump
Fertilizer pump is an explosive and fire-safe fertilizer, so for its transportation you can use electric pumps with a motor in general industrial design, however, the flow path of such pumps must be made of a material resistant to ammonia and nitric acid derivatives. Such materials are stainless steel and plastics (PP, PVDF). For pumping ready-made urea-ammonia mixtures our the company offers pumps with a stainless flow part UAN - a mixture of aqueous solutions of ammonia nitrate and urea (in a ratio of 35.4% urea, 44.3% nitrate, 19.4% water, 0.5% ammonia water). Density product up to 1.34 kg /m3. The only nitrogen fertilizer that contains three forms of nitrogen: nitrate - provides instant action, ammonium - in the process of nitrification goes into nitrate form, amide - into as a result of the activity of soil microorganisms, it passes into the ammonium form, and then into the nitrate form. So Thus, UAN provides prolonged nitrogen nutrition for plants. Due to the lack of free ammonia, it does not evaporate into the atmosphere when introduced, however, the presence of the ammonium form still makes the minimum embedding desirable, especially in conditions
