Technical Resources & Support
Access the technical resources you need for your GWSP oil-free scroll vacuum pump, including operation and installation manuals, 3D CAD models, factory test reports, and step-by-step maintenance videos.
Whether you are preparing for system integration, installation, or routine service, our support center provides practical documentation and technical guidance to help you keep your vacuum system operating reliably.
GWSP oil free scroll vacuum pump is constructed with pump head assembly, crank pin assembly, bracket assembly, air flush assembly, and exhaust valve assembly. Two spiral cylinders, one offset and orbiting against the other fixed with an offset of 180° to form several crescent-shaped pockets of different sizes. By means of an eccentric drive, the orbiting scroll is made to orbit about the fixed scroll, reducing the volume of the pockets and compressing gas from outside towards the inside thereby pumping the gas from vacuum chamber.
