About Sulzer RT-Flex Engine Spare Parts Supply
The Sulzer RT-Flex series is a family of low-speed, two-stroke, common-rail marine diesel engines widely used for main propulsion on container ships, bulk carriers, tankers and other large ocean-going vessels. Because these engines use a common-rail electronic fuel injection and exhaust valve actuation system instead of a conventional camshaft, spare parts for RT-flex engines — particularly fuel injection and hydraulic control components — carry a premium cost when purchased new. We help ship owners, ship management companies and marine repair yards reduce maintenance costs by supplying used (second hand) and reconditioned (refurbished) RT-flex spare parts that meet functional and performance standards at a fraction of new-part pricing.

Used (Second Hand) vs. Reconditioned (Refurbished) — Which Should You Choose?
♻️ Used (Second Hand) Parts
Removed from decommissioned or upgraded engines, inspected for physical condition and remaining service life — a lower-cost option for buyers wanting genuine OEM-manufactured parts without new-part pricing.
🛠️ Reconditioned (Refurbished) Parts
Cleaned, machined/re-worked to tolerance, tested, and restored to a functional and performance standard close to new — ideal for critical components like injectors, fuel pumps and cylinder covers.
