Pump components
Machined parts for hydraulic pumps, made to drawing.
SEG-05 · Industry
Hydraulic
Precision in every drop. Our hydraulic components support efficient, reliable fluid power, from high-pressure pumps to advanced valve systems.
Components we make for hydraulic systems.
Valve bodies
Valve bodies and blocks with accurate port positions.
End caps & glands
Flanged end caps and glands for cylinders.
Precision bushes
Bushes with controlled bores for sliding and rotating parts.

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 |
|---|---|---|---|
| End caps & glands | Close the cylinder and guide the rod | EN8, EN9, SG iron | Seal groove size and finish, concentricity |
| Pistons | Separate the pressure chambers | EN8, SG iron | Outside diameter and groove tolerances |
| Rod eyes & clevises | Connect the cylinder to the machine | Forged EN8 or EN19 | Pin bore size, thread |
| Valve bodies & manifold blocks | Route oil between components | EN8, mild steel, SG iron | Port positions, thread form, burr-free bores |
| Bushes | Guide sliding and rotating parts | Bronze, steel | Bore size and finish |
Industry note
Seal grooves follow the seal maker
Groove sizes and surface finish on hydraulic parts usually come from the seal manufacturer's catalogue. Send the seal make and series with your drawing so the grooves match the seals you will fit.
What matters
What hydraulic parts are judged on.
01
Tight tolerances
Fits between moving parts decide leakage and efficiency at pressure.
02
Surface finish
Sealing and sliding faces need the right finish so seals last.
03
Clean, burr-free parts
Burrs and chips damage seals and valves, so parts must leave the shop clean.
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

- Surface finishSealing and sliding faces checked against the specified finish.
- Threads and portsPort threads and positions gauged.
- Clean and burr-freeParts deburred and cleaned before packing.
FAQ
Common questions.
Can you supply cylinder parts as a set?
Yes. We can supply end caps, glands, pistons and rod eyes together for each cylinder size, made to your drawings.
How do you keep hydraulic parts clean?
Parts are deburred and cleaned before packing, because chips and burrs damage seals and valves.
Which materials are typical?
End caps, glands and pistons commonly use EN8, EN9 or SG iron, and rod eyes forged EN8 or EN19. We follow the grade on your drawing.
