We perform both back filing and front filing. Back filing is a process of material removal on the non-pressure side of the vane. Our 35-year practice has given us cutting and grinding expertise to provide a uniform shape with a gradual transition and establishing dimensional uniformity at the exit vane's tips. Our grinding method has also given us the ability to remove all contaminants and scales that have been formed after the cast operations.
We use the best materials ideal for polishing impellers of all materials. Production commences with a hard grit abrasive for stock removal, followed by a medium grit abrasive for blending defects, and finally a fine abrasive for a flawless surface. Our staff is focused on quality craftsmanship in:
1. Heavy removal & leveling
2. Defects removal & smoothing
3. Flawless & brilliant finish
No impeller is alien to us. We provided service to the most intricate to the most simple impellers ranging in various sizes and dimensions, uses, and industries. Some include open impellers, semi-open impellers to closed impellers, single or double suction impellers. We've also provided service to impellers with backward or forward curved blades or in a radial blade design.
We are glad to hold a personal reputation by name with leading companies for fine craftsmanship, accuracy, and capability. Our filing and polishing services contribute to many global impeller dynamic centrifugal pump systems. This includes industries such as:
