The choice of pump seal oil is crucial. It must have the right viscosity to ensure proper lubrication under varying temperatures and operating conditions. It should be compatible with both the pump materials and the processed fluid to avoid chemical reactions that could degrade the seal's performance. Moreover, it should possess good thermal stability and, resisting degradation even under high heat conditions Moreover, it should possess good thermal stability and, resisting degradation even under high heat conditions

1. Seal Face Diameter The diameter of the seal face is a critical measurement that influences the sealing effectiveness. The Type 2021 typically has a seal face diameter ranging from 1.5 inches to 5 inches (38 mm to 127 mm), depending on the specific application. A larger diameter generally provides a greater surface area for sealing and helps accommodate variations in alignment.
