Impellers, casings, shafts, wear rings and seal components — cast and CNC-machined in stainless, duplex, bronze and high-chrome alloys. Send a drawing, a sample or a nameplate photo and we will come back with a quotation.
Six component families covering the wear parts of centrifugal, slurry and process pumps.
Closed, semi-open and open impellers cast and CNC-finished to your drawing, dynamically balanced before shipment.
View details ›Volute and diffuser casings assessed around flange faces, registers and nozzle locations for drop-in fit.
View details ›Turned, ground and keyed shafts with controlled runout, thread and sleeve seats machined to tolerance.
View details ›Case and impeller wear rings in matched pairs, clearance set to the service and the pumped fluid.
View details ›Seal components and stationary seats, lapped faces, supplied to sample or to a dimensioned print.
View details ›Sleeves, spacers and bearing housings machined from bar or castings in matching alloys.
View details ›Most replacement parts arrive as a worn casting, a smudged print or nothing but a nameplate. We work backwards from whatever you have — reverse-engineering the hydraulic profile, confirming the interfaces that must fit, then selecting the casting route that suits the quantity.
Alloy choice is driven by chloride content, abrasion and temperature — not by the name of the fluid.
| Alloy | EN / spec | Typical service |
|---|---|---|
| CF8M / 316SS | 1.4408 | General chemical duty, mild corrosives, water and wastewater |
| CD4MCu / CD4M | 1.4517 | Duplex — chloride and erosion resistance, seawater and slurry |
| CN7M / Alloy 20 | 2.4660 | Sulphuric acid and mixed acid service |
| WCB carbon steel | 1.0619 | Clean water, oils, general non-corrosive duty |
| Bronze C95800 / C90300 | — | Seawater, marine and fire pump components |
| High-chrome 27% Cr | A532 | Abrasive slurry, mine dewatering, ash handling |

Chloride content, abrasion and cost drive alloy choice more than the pumped medium's name.
