Rebuild record / Powerflo shop
It arrived old and leaking. Teardown found a casing at the end of its life, worn seal faces, and a worn shaft. It left the shop running true and pressure tested.
The 8196 came in on a pallet with years of service behind it. Before a wrench touches anything, the pump gets photographed as received and logged against its nameplate, so every finding that follows can be traced back to the condition it walked in with.
As received
The pump comes apart completely — no partial teardowns, because a leak path is rarely where the customer thinks it is. Every component is laid out, measured, and photographed.
The casing bore told the story immediately: heavy scale and pitting well past the point where a machining pass would save it. The impeller vanes were buried in rust, the seal faces were worn, and the shaft had lost its finish.
Findings Casing at end of life · seal faces worn · shaft worn · stuffing box requires replacement.
Condition report / Scope of work
Powerflo quotes the full repair, then documents exactly what the customer authorizes. Nothing gets buried in a line item.
| Component | Condition found | Disposition |
|---|---|---|
| Casing | End of life — corrosion/erosion past salvage | New casing |
| Mechanical seal | Seal faces worn | Chesterton 1810 HD |
| Shaft | Bearing fits out of spec | Summit shaft kit |
| Bearings | Replaced as standard on rebuild | New |
| Gaskets & o‑rings | Consumable, always renewed | New |
| Impeller | Serviceable | Blasted & balanced |
| Frame adapter | Surface rust | Media blasted |
| Bearing frame | Bearing bore fits found in spec | Media blasted |
| Stuffing box | Surface rust, serviceable | Media blasted |
| Inpro seals | Serviceable | Rebuilt with new O‑rings |
A Chesterton 1810 Heavy Duty cartridge seal and a Summit shaft kit went in alongside the new casing. The frame adapter, bearing frame, and impeller were media blasted back to bare metal to strip the rust build‑up rather than paint over it.
The impeller was then balanced — the difference between a pump that simply runs and a pump that runs true and doesn't eat its new bearings.
Fitted Chesterton 1810 HD cartridge seal · Summit shaft kit · new casing · balanced impeller.
Shaft into the bearing frame, bearings pressed and seated, cartridge seal set, then the wet end closed up. One technician owns the job from teardown to test, so nothing gets lost in a handoff.
Every assembled pump is hydrostatically tested in the shop. The wet end is filled, pressurised, and held for 30 minutes while we watch for weeps at the seal, the case gasket, and every joint. Once passed, the pump is tagged with the approved test results and the technician's signature. The pump does not go on the truck until it passes the test.
Result No leaks. Released for delivery.
Delivery
The same 8196 that came in leaking went home rebuilt, balanced, pressure tested, and painted — at a fraction of the cost and lead time of a new pump.
