Seal Variations by seal part number: (choose from dropdown menu above):

• F21-0C030NS0001-0 – Fits HCP 80AFU27.5MTS/MS & 80AFU43.7

Choose the correct seal part number based on your specific pump model. The HCP AF Series uses different mechanical seal sizes for different motor ratings – 30 mm, 40 mm, and 45 mm seal assemblies are available to cover various pump models in the series.

Note: In HCP model numbers (e.g. 100AFE415), “AFE” denotes the pump series/type (AF Series, specific impeller or design variant), the leading “4” indicates a 60 Hz model, and the following digits (e.g. 15) represent the motor’s kW rating (15?kW in this example), which correlates to the required seal size. Always match your pump’s full model code to the correct seal part number to ensure proper fit.
