2012 06 Bungartz The Use Of Hydrodynamic Sealed Pumps In Ammonium Nitrate and Urea Melt
Bungartz horizontal centrifugal pumps with hydrodynamic shaft seals have proven to be very reliable in applications of the fertilizer industry. The hydrodynamic shaft seal works frictionless without any wear which contributes to high reliability and low maintenance cost. Furthermore no additional heat is introduced to the system, leading to a higher safety of the pump process.
The hydrodynamic seal is leak free during operation and does not require any additional sealing liquid. With special modifications this type of pumps are especially suitable in Ammonium Nitrate and Urea Melt applications.
The presentation will explain the working principle of the hydrodynamic shaft seal, point out the advantages in Ammonium Nitrate and Urea Melt applications and give some typical examples for the use in such applications.
