Six Key Factors for Mechanical Seal Selection

Medium: Specify the type of sealed medium, such as water, engine oil, corrosive liquid.

Temperature: Mark the operating temperature range of the medium, which serves as the basis for material and process selection.

Inlet pressure: Provide the inlet pressure parameter of the medium, which affects the structural design of the seal.

Shaft diameter: Accurately fill in the shaft diameter of the equipment to ensure proper fitting of the seal.

Flushing plan: Clarify whether flushing is required and the specific plan, e.g., Plan 11, Plan 23, which involves cooling and lubrication design.

Pump material: Serve as a necessary reference for selection. The material of the mechanical seal shall be equivalent to or superior to that of the pump.
