OEM Seal and Gasket Kit for HCP 80AFU23.7A and 80AFU23.7LA 5 HP Sewage Pumps
Product Overview
The HCP 80AFU23.7A is the 5 HP model in the AFU sewage pump line, built for higher-flow lift stations and commercial wastewater systems that exceed the capacity of the 2-3 HP models. The HCP mechanical seal kit S21C250G01 is the OEM sewage pump seal kit for this pump, using a larger C250 seal to match the heavier shaft and motor. This kit includes the mechanical seal, oil seal, and gasket kit for a complete seal rebuild.
What's Included
Each S21C250G01 mechanical seal kit contains three components:
| Component | Specification | Qty |
|---|---|---|
| Mechanical Seal | Per S21C250001 reference | 1 |
| Oil Seal | Per S21C250001 reference | 1 |
| Gasket Kit | Complete gasket set for 80AFU23.7A / 80AFU23.7LA | 1 |
Compatibility
Compatible with HCP pump models:
• 80AFU23.7A (5 HP, single phase and three phase)
• 80AFU23.7LA (5 HP, long-cable variant)
Buyers searching for an 80AFU23.7A seal kit need this part number: S21C250G01. The A and LA variants share the same 5 HP sewage pump seal configuration. The LA suffix indicates a longer power cable for deeper wet well installations, not a different seal arrangement.
This kit does NOT fit the 2-3 HP AFU models (80AFU21.5, 80AFU22.2). Those pumps use the smaller S21B200G06 seal kit.
Key Features
• Larger C250 seal size matched to the 5 HP motor's heavier shaft, providing the sealing surface area needed for higher-output sewage pump applications.
• The dual seal system in AFU pumps uses a carbon/ceramic upper seal and silicon carbide lower seal in an oil-filled chamber. This HCP mechanical seal kit replaces both sealing surfaces.
• Gasket kit included for a complete submersible pump seal kit rebuild. Replacing seals without fresh gaskets risks leaks at the housing joints.
When to Replace
The 80AFU23.7A handles higher flows and greater solids loads than the 2-3 HP AFU models, which puts more stress on the seal faces over time. Replace this sewage pump seal kit when oil chamber inspections reveal discoloration, when insulation tests show moisture reaching the motor windings, or after any dry-running event.
Scheduling HCP AFU pump seal replacement during planned shutdowns keeps service interruptions short and prevents the cost of a flooded motor.

FAQs
Which HCP pump does the S21C250G01 seal kit fit?
This HCP mechanical seal kit fits two models: the 80AFU23.7A (5 HP) and the 80AFU23.7LA (5 HP, long cable). Both use the same C250 seal. It does not fit the 2-3 HP AFU models.
What is the difference between the 80AFU23.7A and the 80AFU23.7LA?
The A and LA designations share the same pump housing, motor, and seal system. The LA variant has a longer power cable for deeper wet well installations. One seal kit covers both.
Why is this a different seal kit than the S21B200G06?
The S21C250G01 uses a larger C250 seal for the 5 HP motor shaft. The S21B200G06 uses a smaller B200 seal for the 2-3 HP models. Installing the wrong size will not seal correctly and can damage the pump.
What seal size does the 5 HP HCP sewage pump use?
The 80AFU23.7A uses a larger C250 mechanical seal. The 2-3 HP AFU models use the smaller B200 seal. These are different sizes and not interchangeable. Order part number S21C250G01 to ensure correct fit for the 5 HP pump.
Does Cleanflow carry HCP AFU seal kits for all sizes?
Yes. Cleanflow stocks HCP sewage pump seal kits for the full AFU range: 2 HP, 3 HP, and 5 HP models. We also carry seal kits for the AFE, AFP, and GF Series. Call 1-866-335-1078 for availability.
