Kobelco parts and consumables listed here
Three compressor items are listed: the VGP31649#01 rotor assembly for the third and fourth stage, a lubricator assembly and a low level alarm pump assembly. These are machine-specific spares. The fourth item is Kobelco DW-50, a rutile flux-cored welding wire for carbon steel that the manufacturer classifies as AWS A5.20 E71T-1C/1M.
Ordering Kobelco spare parts: what we need
Compressor spares are identified through the machine, not through a catalog. Send the compressor model and serial number from the nameplate, the Kobelco part number, and the item number and drawing number from the parts list in your manual. A photo of the old part and its markings helps. For Kobelco welding wire, send the trade name, the AWS classification your procedure calls for, the wire diameter, spool weight and quantity. We handle Kobelco compressor parts inquiries from across the GCC and check every part number against the manufacturer documentation.

Frequently Asked Questions
How do I identify a Kobelco compressor spare part?
Use the parts list supplied with the compressor. Each item has a part number, such as VGP31649#01, tied to the machine serial number. Send the part number, the item and drawing number, and the compressor model and serial number. Part names alone, like rotor or lubricator, are not enough.
Why is the compressor serial number needed for a rotor assembly?
Rotor assemblies are built for a specific machine and stage. The serial number lets the manufacturer confirm the frame, stage, profile and any design changes made after shipment. Without it, a part number taken from an old manual may point to a superseded design.
What is Kobelco DW-50 welding wire?
DW-50 is a rutile flux-cored wire for carbon steel, used with CO2 or argon-CO2 shielding gas. The manufacturer classifies it as AWS A5.20 E71T-1C/1M and E71T-9C/9M. Similar names such as DW-50EA and DW-A50 are different wires, so copy the trade name exactly. For mechanical properties, compare the manufacturer datasheet with your welding procedure before ordering.
What should I send for a Kobelco quotation?
For compressor parts: machine model, serial number, part number, description and quantity, with a nameplate photo. For welding wire: trade name, diameter, packaging and total weight, plus any certificate your project requires. We check the data against the manufacturer documentation before quoting.
Is Seven Star LLC a distributor of Kobelco?
No. Seven Star LLC is an independent industrial supplier based in Muscat. We source Kobelco parts and consumables through commercial channels, check the model or order code against the manufacturer's documentation before quoting, and provide the manufacturer's datasheet and the certificates the manufacturer issues with the order on request.
