Parts & materials
Typical parts, materials and what we hold.
Typical grades for guidance. We always follow the material on your drawing.
| Component | Function | Typical materials | Critical features |
|---|---|---|---|
| Pump barrels & bodies | House the rotating assembly and hold pressure | CI, SG iron or steel | Bore size, face flatness, sealing faces |
| Pump shafts | Carry the impeller and transmit power | EN8, EN19, SS410, SS304 | Runout, journal finish, keyways |
| Shaft sleeves | Protect the shaft at seals and glands | SS410, SS304 | Outside finish, concentricity |
| Coupling hubs | Connect motor and pump | EN8, SG iron | Bore and keyway, face runout |
| Bearing housings | Support the shaft bearings | SG iron, cast steel | Bearing seat size and alignment |
| Glands & covers | Hold packing or mechanical seals | EN8, CI, bronze | Seal bore, face finish |
Industry note
Built for variants
Pump makers run many sizes and ratings on a common platform. Tell us the part family and expected volumes, and we can plan fixtures that make switching between variants quick.
What matters
What pump parts must get right.
01
Concentricity
Shafts and bores that run true keep vibration down and bearings and seals alive.
02
Sealing surfaces
Faces and bores that carry seals need the right finish and flatness to hold pressure without leaks.
03
Quick new variants
Pump makers change ratings and sizes often. In-house design and automation help us turn new drawings around fast.
Manufacturing route
From drawing to dispatch.
01
Drawing review
Material, tolerances, quantities and inspection needs checked up front.
02
Blank
Forging, bar or plate, chosen for the strength and size the part needs.
03
Rough machining
Stock removed with allowance left for the final operations.
04
Heat treatment
Hardening, normalising or case hardening, where the drawing specifies it.
05
Finish machining
Bores, journals, faces, keyways, splines and threads brought to final size.
06
Assembly, inspection & dispatch
Assembled if required, checked against the drawing, protected and packed.
Quality
What we check on pump parts.
- RunoutShafts and sleeves checked so the rotating assembly runs true.
- Sealing facesFinish and flatness on faces and bores that carry seals.
- Bores and keywaysCoupling and impeller fits gauged.
- Dimensions to drawingEvery critical size checked before dispatch.
FAQ
Common questions.
Which material should a pump shaft be?
It depends on the liquid and the duty: EN8 or EN19 for clean water and general service, SS410 or SS304 where corrosion matters. We follow the grade on your drawing.
Can you supply shafts with sleeves fitted?
Yes. We build sub-assemblies, so shafts can be supplied with sleeves, keys and other parts fitted as specified.
Can you take on new pump models quickly?
Yes. In-house design and automation let us bring up new parts and variants quickly.
