NorthStar Self-Priming Semi-Trash Water Pump - 4in. Ports, 23,040 GPH, 3/4in. Solids Capacity, 270cc Honda GX270 Engine

Long-life silicon carbide mechanical seal resists corrosion, wear and heat better than a standard seal.
Cast iron impeller and volute last longer for semi-trash operations.
Silicon carbide seals are 2 times harder, 15% tougher, and 50% stronger than common aluminum oxide seals.

★【4 Steps】Be Patient. There are 4 total cycles, 7 days each to have pretty rocks / gems. Step 1, 60 Coarse Silicon Carbide Grit. Step 2, 220 Medium Silicon Carbide Grit. Step 3, 500 Fine Silicone Carbide Grit. Step 4, 1200 Aluminum Oxide Grit. Just measure in the grit, add enough water to cover the stones, seal the barrel, and tumble. The only variable is how much of the product to use in your rock tumbler. We suggest 2 tbsp of grit per pound of stones, which is a good rule of thumb..
★【Large Amount of Grit】This is a large amount of each size grit for the price. This kit comes with enough grit to complete approximately 16-20 lbs of rocks. This kit contains 2 lbs 60 Coarse Silicon Carbide Grit, 2 lbs 220 Medium Silicon Carbide Grit, 1 lb. 500 Fine Silicone Carbide Grit, 1 lb. 1200 Aluminum Oxide Final Polish Grit. COMPATIBLE WITH ALL BRAND TUMBLERS..
★【Jars, Labels & a Scoop】Nice hard plastic jars with lids (as opposed to plastic bags). Bottle caps are very secure. Definitely they will not leak. Use the amount you need and set it back on the shelf for the next round. A scoop is included for the correct dose. No need to pour the material out, which possibly make a mess while doing so. They are neatly packaged and easy to read labels....
