WinGD & Sulzer Marine Engine Spare Parts — OEM & Aftermarket

Banomad B.V. is an independent marine spare parts supplier delivering OEM and quality aftermarket parts for WinGD low-speed two-stroke main engines and the large Sulzer / Wärtsilä-Sulzer RTA and RT-flex installed base. We work directly with manufacturers and primary stockists — no middlemen — so ship owners, operators and technical superintendents can source the right part fast, with compatibility confirmed against engine type and serial number. (WinGD — Winterthur Gas & Diesel — is the successor to the Sulzer / Wärtsilä-Sulzer two-stroke line; the engines are still specified across the market as Sulzer, RTA, RT-flex and WinGD X.)

Frequently asked questions

Do you cover RTA, RT-flex and the new X-Generation engines?

Yes. We source parts for mechanically controlled RTA engines, common-rail RT-flex engines and the current WinGD X and X-DF series.

Can you supply parts for older Sulzer engines?

Yes. A large share of the fleet still runs Sulzer RTA and earlier RND / RL engines, and we regularly source parts for them.

What do you need to prepare a quote?

The engine type/model and the part number or a clear description (a photo of the nameplate helps). The engine serial number lets us confirm the correct revision.

Do you ship worldwide?

Yes. We deliver to ports and yards worldwide under flexible Incoterms.
