GT11D5 Spare Parts We Manufacture
ZURN Power covers the GT11D5 parts scope for the ABB / Alstom GT11 heavy-duty gas turbine line. Component families are produced in-house against OEM drawings or reverse-engineered from a supplied sample, with material and dimensional control matched to OEM specification.
- Turbine Blades — Hot gas path rotor blades for the GT11 expander, in nickel-base superalloy.
- Turbine Vanes & Nozzles — Nozzle segments and vane rows for hot gas path service.
- Combustor Hardware — Burner parts, liners, tile carriers and heat shield tiles to the unit combustor arrangement.
- Compressor Blading — Compressor rotor blades and stator vanes, diaphragms and seal strips.
- Rotor Components — Rotor spacers, sealing rings, coupling and balance hardware to drawing.
GT11D5 Hot Gas Path Components
On the GT11 line the maintenance cost concentrates in the hot gas path: rotor blades, nozzle segments and shroud hardware all run at high metal temperature with cooling air that degrades over time. ZURN Power manufactures GT11D5 hot gas path components in Inconel 738-class and equivalent nickel-base superalloys, with thermal barrier coating applied on request. Castings are finished by 5-axis machining and verified with full dimensional reports, so replacement parts install without rework and keep the inspection interval on schedule.
GT11D5 Combustion System Parts
Combustion hardware for the GT11 line is supplied against your unit arrangement — most N and D frames use silo-type combustors, but geometry differs by revision and by any conversion or uprate already performed on the machine. Send the burner arrangement or drawing with the RFQ and we quote hardware that matches, including burner internals, liners, tile carriers and heat shield tiles, with material traceability and EN 10204 3.1 certification.
GT11D5 Compressor & Rotor Parts
The axial compressor drives output and heat rate across the whole machine. ZURN Power manufactures compressor rotor blades, stator vanes, diaphragms and seal strips, plus rotor spacers and coupling hardware, strictly to drawing. Blades are batch-inspected for profile, root fit and balance, supporting both full rotor overhauls and single-stage replacements.
Ordering from a Drawing or BOM
Ratings, stage counts and burner arrangements vary by frame revision and by any uprate already applied. We do not guess part numbers — send the OEM number, drawing or a sample and we quote against it.
| Component family | What we need from you | Typical lead time |
|---|---|---|
| Turbine blading | Part number or drawing + revision | 8–14 weeks |
| Combustor hardware | Combustor arrangement / drawing | 8–14 weeks |
| Compressor blading | Stage + part number | 8–14 weeks |
| Rotor components | Drawing + material spec | 8–14 weeks |

Frequently Asked Questions
Which GT11D5 parts does ZURN Power manufacture?
Turbine blades and nozzle segments, combustor hardware including burner internals, liners and heat shield tiles, compressor rotor and stator blading, and rotor spacers, sealing rings and coupling hardware — to OEM drawings or reverse-engineered to sample.
Do you cover the whole GT11 line?
Yes. We also manufacture for GT11NM, GT11N1, GT11N2 and GT11D4. Component geometry and part numbers differ by frame and revision, so we quote against your part number or drawing.
Are your GT11D5 components certified?
Yes. EN 10204 3.1 material certificate, heat-lot traceability and a dimensional inspection report ship with every part.
What is the lead time for GT11D5 spare parts?
Standard lead time is 8–14 weeks depending on component type, coating requirement and casting complexity.
