The rated pressure of a high viscosity gear pump refers to the higher allowable pressure of a SUS high viscosity gear pump during continuous operation, and its working pressure is determined by the external load. The life of a high-viscosity gear pump is directly related to its working pressure. For high-viscosity gear pumps that work infrequently, the working pressure can be taken as the rated pressure of the pump. Considering the difference in product quality, the rated pressure is reduced by 20% to 30%. For high-viscosity gear pumps that often work at higher pressures, the working pressure should be 1 to 2 pressure levels lower than the pump's rated pressure. Petrochemical equipment often runs continuously for 24 hours. At this time, the working pressure of the high-viscosity gear pump should be much lower than the rated pressure, and the working speed should also be lower than the rated speed. If the working pressure of the high-viscosity gear pump is adjusted too high, the high-viscosity gear pump will run under overload.
