The Siemens V94.2 (now designated SGT5-2000E) is one of the most widely installed 50 Hz heavy-duty gas turbines in the world, with more than 300 units operating in combined cycle, cogeneration and industrial power applications. Originally developed by Siemens and later produced under license by partners including Shanghai Electric, the V94.2 fleet remains a workhorse across China, Europe, the Middle East and Southeast Asia.
As the installed base ages, operators face longer OEM lead times, discontinued part numbers and rising spare parts costs. ZURN Power supplies V94.2 spare parts manufactured to OEM drawings and material specifications, with lead times typically 30–50% shorter than the original manufacturer.

Applications
The V94.2 / SGT5-2000E is deployed in a wide range of power generation configurations:
- Combined-cycle power plants (1×1, 2×1 configurations)
- Cogeneration and district heating stations
- Industrial captive power (petrochemical, steel, oil & gas)
- Peaking and grid-stability installations
Quality & Certification
Every V94.2 spare part is produced under our ISO 9001:2015 and AS9100D quality system. Material sourcing starts with certified ingot or bar stock (EN 10204 3.1), followed by investment casting or precision machining, heat treatment, coating application and final dimensional inspection. We provide full documentation packages for operator quality records and insurance surveys.
Frequently Asked Questions
What is the Siemens V94.2 power output?
The V94.2 delivers approximately 166 MW in simple-cycle ISO conditions and roughly 223 MW in a standard combined-cycle block configuration.
Are V94.2 and SGT5-2000E parts interchangeable?
Yes. SGT5-2000E is the current Siemens designation for the V94.2 platform. Most hot-gas-path and compressor parts cross-reference directly, though sub-revisions must be verified by serial number.
Can you supply V94.2 parts faster than the OEM?
Yes. Our typical lead time is 8–14 weeks for cast hot-section parts and 4–8 weeks for machined compressor components, with smaller minimum order quantities.
Do you support Chinese-built V94.2 units?
Yes. We cross-reference parts for Siemens, Shanghai Electric and licensed V94.2 builds. Send your part number or unit serial for verification.
