Description
OEM Seal and Gasket Kit for the HCP 80AFP41.5 Semi-Open Impeller Sewage Pump
Product Overview
HCP builds the AF sewage pump family around three impeller types: vortex (AFU), enclosed channel (AFE), and semi-open (AFP). Each type uses a different seal kit. The HCP mechanical seal kit S21B250G01 is the OEM sewage pump seal kit for the 80AFP41.5, which uses a P-type semi-open impeller with single or twin vanes to pass large solids without clogging.
What's Included
Each S21B250G01 sewage pump seal kit contains three components:
| Component | Specification | Qty |
|---|---|---|
| Mechanical Seal | Per S21B250001 reference (hcppumps.ca) | 1 |
| Oil Seal | Per S21B250001 reference (hcppumps.ca) | 1 |
| Gasket Kit | O-ring and gasket set for 80AFP41.5 | 1 |
Compatibility
Compatible with HCP pump model:
• 80AFP41.5 (2 HP, 4-pole, 3" discharge, semi-open impeller)
For 80AFP41.5 seal replacement, order part number S21B250G01. This AFP pump seal kit fits only the 80AFP41.5. It is not interchangeable with the AFU or AFE seal kits, even though all three are part of the HCP AF pump family.
Confirm you have the correct HCP mechanical seal kit by matching the model number on your pump's nameplate to the quick reference table below.
Key Features
• Semi-open impeller design: the P-type impeller's open vane structure handles large solids and fibrous waste while maintaining flow. The semi-open impeller pump seal in this kit matches the sealing requirements of that design.
• Double mechanical seal with carbon/ceramic and silicon carbide faces, permanently lubricated in an oil-filled chamber. This HCP mechanical seal kit replaces the full seal assembly.
• Applications include wastewater treatment plants, drainage systems, flood control, livestock operations, and irrigation, all environments where the submersible pump seal kit must withstand abrasive particles in the flow.
When to Replace
Semi-open impellers expose more of the impeller surface to the pumped fluid than vortex designs, which means abrasive particles in sewage contact the seal area more frequently. Check the oil chamber during routine maintenance. Discolored or milky oil, motor thermal trips, and visible moisture on the pump housing are all signs this sewage pump seal kit is due for replacement.

FAQs
Which seal kit fits the HCP 80AFP41.5?
The S21B250G01 is the OEM sewage pump seal kit for the 80AFP41.5. It includes the mechanical seal, oil seal, and gasket kit. This part number fits only the AFP model and cannot be used on AFU or AFE pumps.
What is the difference between AFP, AFU, and AFE HCP pumps?
All three are AF Series sewage pumps with different impellers. AFP uses a semi-open (P-type) impeller, AFU uses a vortex (U-type), and AFE uses an enclosed channel (E-type). Each requires its own seal kit.
What is a semi-open impeller and how does it affect the seal?
A semi-open impeller has exposed vanes that move fluid through direct contact, handling large solids effectively. This design puts more abrasive stress on the seal faces than a vortex impeller, making regular seal inspection important.
Are HCP AF Series seal kits interchangeable between sub-series?
No. AFP, AFU, and AFE pumps each use a different seal kit with a different part number. The AFP uses S21B250G01, the AFU uses S21B200G06 or S21C250G01, and the AFE uses S21B300G02. Always match by model.
Does Cleanflow stock all HCP sewage pump seal kits?
Yes. Cleanflow carries HCP sewage pump seal kits for the AFP, AFU, AFE, and GF Series. All kits ship across Canada and the USA with free shipping on orders over $199. Call 1-866-335-1078 for availability.
