Filing

We've perfected the impeller cutting and grinding techniques to provide a uniform shape with a gradual transition and establishing dimensional uniformity at the exit vane's tips.

We perform both back filing and front filing. Back filing or under 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 back file impellers, pump bowls and suction bells.

Impeller Polishing

To improve impeller efficiency and performance, polishing is widely used for many purposes including higher flow rates and energy savings. We smooth out all surface faults, imperfections, or unsatisfactory breaks on the impeller vanes at near 20 RMS surface finish.

We use the best materials ideal for polishing impellers, pump bowls and suction bells 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. We're focused on quality craftsmanship in:
1. Heavy removal & leveling
2. Defects removal & smoothing
3. Flawless & brilliant finish

Casting Surface Finishes

We're here to help assist in surface finishings for all castings & materials where machines can not preform. We handle the inner workings, impeller vanes and impeller shroud to finished products by smoothing its surface to specifications. Using the cast microfinish comparator, you can expect any finish: 0 RMS, 20 RMS, 60 RMS, 120 RMS, or 200 to 900 RMS surface finish.

We can use abrasive rolls to smooth rough surfaces. Our technique provides the best finishes to an even higher quality. Our staff can guide and assist you by providing solutions to all your casting surface finishing needs. Contact us or request a quote.

Impeller Types

Our mission is to provide service to many types of impellers. Over the years we've seen impellers for many different applications and of many different types roll through.

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.
