Slurry Pump Hacks Every Millwright Should Know Slurry Pump Hacks Every Millwright Should Know
Slurry Pump Hacks Every Millwright Should Know Slurry Pump Hacks Every Millwright Should Know 1 Safest Way to Remove a Stuck Impeller 2 Properly Pack Your Stuffing Box 3 Tricks to Tightening Mechanical Seals 4 Best Method for Shaft Sleeve Removal 5 Easiest Way to Mount Snap Ring Gaskets 2 Slurry Pump Hacks Every Millwright Should Know Safest Way to Remove a Stuck Impeller Impellers can get stuck for many reasons. Here are two common problems you’ll see in the field: Did You Know? ■ Using only one gasket or none at all — it is important to always Putting a new impeller on use two gaskets. They work against one another for easier worn threads results in removal. When you use one, the impeller will want to overtighten on the shaft, so it makes it more difficult to get off. Two gaskets rapid failure and damage slide against one another, making it easier to break loose. If you to other wet-end parts. don’t use any gasket at all, it all galls together. ■ Applying anti-seize to the hub face — People like to use anti-seize on the threads, faces of the shaft sleeve, the impeller, and the gaskets. That actually causes it to overtighten: It allows the parts to become more slippery and it will overtighten on the shaft. A good rule of thumb is if you want to use anti-seize on the threads of the shaft and the impeller, keep the axial faces of the shaft sleeves, the gaskets, and the impeller hub dry. If you get anti-seize on those areas, the impeller will tighten even further on the shaft. -

Manufacturing Glossary
MANUFACTURING GLOSSARY Aging – A change in the properties of certain metals and alloys that occurs at ambient or moderately elevated temperatures after a hot-working operation or a heat-treatment (quench aging in ferrous alloys, natural or artificial aging in ferrous and nonferrous alloys) or after a cold-working operation (strain aging). The change in properties is often, but not always, due to a phase change (precipitation), but never involves a change in chemical composition of the metal or alloy. Abrasive – Garnet, emery, carborundum, aluminum oxide, silicon carbide, diamond, cubic boron nitride, or other material in various grit sizes used for grinding, lapping, polishing, honing, pressure blasting, and other operations. Each abrasive particle acts like a tiny, single-point tool that cuts a small chip; with hundreds of thousands of points doing so, high metal-removal rates are possible while providing a good finish. Abrasive Band – Diamond- or other abrasive-coated endless band fitted to a special band machine for machining hard-to-cut materials. Abrasive Belt – Abrasive-coated belt used for production finishing, deburring, and similar functions.See coated abrasive. Abrasive Cutoff Disc – Blade-like disc with abrasive particles that parts stock in a slicing motion. Abrasive Cutoff Machine, Saw – Machine that uses blade-like discs impregnated with abrasive particles to cut/part stock. See saw, sawing machine. Abrasive Flow Machining – Finishing operation for holes, inaccessible areas, or restricted passages. Done by clamping the part in a fixture, then extruding semisolid abrasive media through the passage. Often, multiple parts are loaded into a single fixture and finished simultaneously. Abrasive Machining – Various grinding, honing, lapping, and polishing operations that utilize abrasive particles to impart new shapes, improve finishes, and part stock by removing metal or other material.See grinding. -
