Repair your HCP AF Series submersible pump with this direct-fit replacement mechanical seal. Designed for HCP sewage/wastewater pumps like 80AFU27.5, 80AFU43.7, 100AFE415, and 100AFE422., this seal restores leak-free performance and protects your pump’s motor from fluid ingress. Each seal is built to OEM specifications for a precise fit, ensuring reliable operation even in demanding industrial and municipal applications. The heavy-duty construction stands up to abrasives and corrosive environments, giving you long-lasting service life with every seal replacement.
- Built to Fit: Direct replacements for OEM seals in AF Series models like 80AFU27.5, 80AFU43.7, 100AFE415, and 100AFE422.

Seal Variations by seal part number: (choose from dropdown menu above):
- F21-0C030NS0001-0 – Fits HCP 80AFU27.5MTS/MS & 80AFU43.7
- F21-0C040CS0000-0 – Fits 40mm seal applications in mid-size AF Series pumps
- F21-0C045CS0001-0 – Fits 100AFE415 / 150AFE415 and 100AFE422 / 150AFE422 (20–30HP models)
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.
