When the OEM impeller is back-ordered for months — or the pump maker is gone entirely — we reproduce the part from your worn sample. Impellers, wear rings, shafts, seal carriers. No drawing needed, MOQ 1.
Pumps wear by design — impellers erode, wear rings open up, shaft journals score. The OEM spares route works until it doesn't: the pump is an older model and parts are discontinued; the manufacturer was acquired and the spares line dropped; the quoted lead time is 16 weeks and the process can't wait; or the OEM price for a simple machined ring is ten times what it should be.
We reproduce pump parts from the worn original — measured on CMM, restored to design geometry, manufactured in the original material or an upgrade.
Open and closed centrifugal — vane profile and hydraulic geometry restored from the worn original.
Bore and OD to original clearance; bronze or coated upgrades for abrasive service.
All journals, keyways, threads and impeller seats to bearing-fit tolerance.
Pilot bore, face run-out and gland pattern reproduced for mechanical seal fit.
Bearing bores, seal grooves, vents and drains to original spec.
Hydraulic geometry matched to the impeller for original performance.
Matched rotor pairs reproduced to maintain displacement.
Shaft couplings, spacers and taper sleeves to OEM fit.
| Pumped fluid | Standard | Upgrade option |
|---|---|---|
| Clean water | Cast iron / bronze | — |
| Seawater | Bronze / 316 | Duplex 2205 |
| Abrasive slurry | Cast iron | Chrome iron, hard-faced |
| Chemicals | 316 | Super duplex, Hastelloy |
| Food grade | 304 | 316L electropolished |
Replace the wear ring with the impeller. A new impeller running against a worn ring still leaks internally — head and efficiency stay low. A matched set reproduced together restores original clearance and original performance. We quote both as a set by default.
Usually yes, significantly. A reproduced impeller from your worn sample is typically 2–3 weeks including CAD reconstruction and your approval. Send photos for a quote within 24 hours and we confirm the timeline for your specific part.
Often yes. If the original wore quickly — abrasive fluid eating cast iron, chloride pitting on 316 — we upgrade the material: chrome iron for slurry, duplex for seawater, hard-coated surfaces for abrasion. Same geometry, longer life.
No. We work from the physical part, not from catalogues. The model number helps for context but the worn part itself — or photos with a known dimension — is what we actually need.
Yes, and we recommend it. Pump efficiency depends on the impeller-to-ring clearance. Replacing both as a matched set restores the pump's original performance rather than running a new impeller against a worn ring.
