Selection of the Mechanical Seal for the Centrifugal Pump II_Changsha Zoomlian Pump Co.,Ltd

发布于:2021年04月15日 作者:zlby 阅读:639
 
When selecting the mechanical seal for any applications consider the following factors also:
 
1) Pressure of the liquid: The liquid enters the pump at certain pressure and the pump has to increase its pressure to certain level so that it reaches certain height. The total pressure on the seal decides whether one should opt for the balanced seal or the unbalanced type of seal.
 
2) Temperature of the liquid: Some pumps handle liquids at high temperatures and others handle the liquids at low temperature. The materials and mating surfaces used in mechanical seals should be able to sustain the temperature of the fluid.
 
3) Nature of fluid: The liquids to be handled by the pump may be having ordinary flow, but there can also be chemical solutions that have high viscosity and slow flow, there can be precipitates, there can be abrasive liquids and so on. These types of fluids usually cause more wear and tear of the parts of the mechanical seals and in such cases it is advisable to use double seals.
 
4) Safety and Environmental concerns: The safety of human being handling the pump is of prime importance so are the permissible emission standards. To be on the safer side it is always better to used double seals that work as the better sealants and are more reliable.
