Impeller Filing

We have refined the impeller cutting and grinding techniques to ensure a uniform shape with a gradual transition, establishing dimensional consistency at the tips of the exit vanes.

We provide both back filing and front filing services. Back filing, also referred to as under filing, is the process of removing material from the non-pressure side of the vane. With years of industry experience, we have developed expertise in cutting and grinding techniques that create a uniform shape with a smooth transition. This process ensures dimensional consistency at the tips of the exit vanes. Furthermore, our grinding method allows for the thorough removal of contaminants and scales that may have developed during the casting operations. We are experts in backfilling for impellers, pump bowls, and suction bells, ensuring optimal performance and reliability for your equipment.

Impeller Polishing

To enhance the efficiency and performance of impellers, polishing is frequently employed for various objectives, including increased flow rates, pump inspections, and energy savings. We meticulously address all surface defects, imperfections, and undesirable breaks on the impeller vanes, achieving a surface finish of 0 RMS.

We utilize the finest materials designed specifically for polishing impellers, pump bowls, and suction bells made from various materials. Our production process begins with a coarse grit abrasive for stock removal, followed by a medium grit abrasive to blend out any defects, and concludes with a fine abrasive to achieve a flawless surface. We are dedicated to quality craftsmanship in:
• In-depth heavy removal and precise leveling.
• Thorough defect removal and smooth finishing.
• Achieve a flawless and stunning result.

Casting Surface Finishes

We specialize in providing surface finishing services for a diverse range of castings and materials where conventional machining methods may not be effective. Our offerings include the treatment of internal components, such as impeller vanes, corners, leading edges, eye openings, pressure-side vanes, and shroud covers. This process ensures the achievement of a smooth surface that adheres to precise specifications. Utilizing the cast microfinish comparator, we are capable of delivering a variety of finishes, including: 0 RMS, 20 RMS, 60 RMS, 120 RMS, or finishes ranging from 200 to 900 RMS.

Impeller Types

Our organization offers services for a diverse range of impellers utilized worldwide. Throughout the years, we have encountered impellers designed for various applications and of numerous types, each demonstrating unique characteristics and functionalities.

At our company, no impeller is beyond our expertise. We specialize in servicing a wide range of impellers, from the most complex designs to the simplest forms, catering to various sizes, applications, and industries. Our experience encompasses open impellers, semi-open, and closed varieties, as well as single and double suction models. Additionally, we adeptly handle impellers featuring backward or forward curved blades, along with radial blade designs. Trust us to deliver top-notch service for all your impeller needs.

Impeller Grinding

Enhancing the efficiency of impellers through precision grinding is essential when pumps fail to meet testing standards. This process not only expands the operational capabilities of the vanes but also contributes positively to the Net Positive Suction Head, particularly in models experiencing elevated levels. We acknowledge that this undertaking may exceed typical requirements, and we are equipped to assist in addressing these challenges effectively.

When it's time to achieve precision, we offer the tools and expertise necessary to expertly grind impeller leading edges and vane tips to conform to engineering standards with a uniform radius. Our proficiency extends to grinding hydraulic passageways, leading edges, shroud covers, and core shift exit vanes for double suction impellers. We are dedicated to meeting our clients' needs in these critical areas:
• Grinding back the leading veins
• Grinding to enhance the passageways
• Adjusting vanes to ensure proper core shift alignment
• Addressing and grinding out imperfections
• Grinding the outer shroud of enclosed impellers
• Eliminating slag, buildup, or excess casting material from the foundry
• Optimizing pump performance
