We are a contract manufacturer. Every part we ship is made from a drawing, a sample or a 3D scan that the customer supplies and is entitled to use. We do not hold a parts catalogue and we do not sell from stock — what we bring is foundry capacity, tooling made in-house, and machining up to 30 t.
Closed and open impellers cast in high-chrome white iron, ductile iron or rubber-covered construction, then machined and dynamically balanced. Vane geometry is reproduced from your drawing or 3D scan — we do not alter hydraulic design without written instruction.
Structural pump castings — volute casings, frame plates, covers, bearing housings and drive-end brackets. Machined on gantry capacity to 4 m × 6 m, with a 35 t crane and a largest single workpiece to date of 30 t.
Volute liners, throat and cover liners, and covered impellers moulded in natural rubber, NBR, EPDM or castable polyurethane. Tooling is cut in our own shop, so liner and mould are dimensionally matched and revisions do not wait on an outside toolmaker.
Unmachined castings supplied to foundries, machine shops and distributors that finish parts on their own equipment. You control the final machining, the inspection record and the identity of the part; we supply sound metal with a material certificate.
Where a customer supplies a full set of drawings, we build and assemble the complete unit — wet end, bearing assembly, frame and base — rather than shipping loose components. Assembly, run-in and packing are handled under one roof.
Grades are quoted against recognised international standards. Where your drawing calls for a national equivalent, we confirm the substitution in writing before pouring.
| Grade | Standard | Typical Use | Hardness |
|---|---|---|---|
| 27% Cr white iron | ASTM A532 Cl. III Type A | Impellers, throat and volute liners | HRC 58 – 65 |
| 15% Cr-Mo white iron | ASTM A532 Cl. II Type B | Wear plates, cyclone components | HRC 55 – 62 |
| Ductile iron 65-45-12 | ASTM A536 | Casings, covers, frame plates | HB 170 – 220 |
| Martensitic stainless | ASTM A743 CA-15 / AISI 431 | Shaft sleeves, expeller rings | HRC 32 – 42 |
| Natural rubber / NBR / EPDM | Compound to spec | Liners, covered impellers, seals | 40 – 70 Shore A |
| Castable polyurethane | Compound to spec | Front liners, cyclone parts, covers | 85A – 95 Shore D |
A wear part is only worth what its metallurgy says it is. Every consignment leaves with the paperwork that lets you verify it independently.
Spectrometer analysis of the actual heat, reported element by element against the specified grade. Heat number is traceable to the individual casting.
Every BatchRockwell readings taken at defined positions on the wear face, not a single convenience point. Sample size agreed with you before production starts.
Every BatchCritical dimensions measured against your drawing and recorded. For complex geometry we issue a 3D scan comparison against the supplied model.
On RequestUltrasonic, magnetic particle or dye penetrant testing where the application calls for it. Rotating parts are dynamically balanced to ISO 21940 G6.3 or tighter.
On RequestWorn components can be 3D scanned at your plant or shipped to us for scanning and model reconstruction, then restored to nominal geometry. This is the normal route when original drawings were lost, or when a part has been in service long enough that the as-worn shape no longer tells you what it started as.
Before you send a sample
We manufacture to the customer’s instruction. By supplying a drawing, model or physical sample you confirm that you are entitled to have that geometry reproduced and that doing so does not infringe a third party’s intellectual property rights in your market. We do not carry, publish or supply any other manufacturer’s drawings, part numbers or model designations, and no part we make is marked with a designation other than our own or the customer’s. If you are unsure of your position, take advice before placing the order — we would rather quote a job that is clean.
