This last impeller I got about 11,000 ton of manufactured sand and about the same amount of natural sand through it before it was toast.
After I made a new wear bushing and increase the size of the packing to 5/8” haven’t had an issue. I just think the 1/2” packing was just too small to work correctly.Wow I missed some updates on this thread.
This mine has started renting all of our surface equipment instead of buying. I believe we have a dealer tech on site every day for support and if it's down for x time they have to drop off a replacement. They got sick of emissions issues costing them money and this was their work around. I think part of the decision was also based on finding people competent enough to troubleshoot the emissions stuff. There's also some sort of accounting advantage as well.
How's the pump working out? I put my packing in dry, a pump engineer told me using patrolium products on the packing fills up all the tiny little cooling passages. He suggested something like dish soap or smooth gojo. They also make a packing install lube, I've never used it. Lubricant for Use With Compression Packing | Garlock
Most of our slurry pumps including our ball mill discharge pump (anything from fine particles to 1/4 that doesn't pass through the ball mill trommel goes through it) have steel impellers. I'll have to do some digging on our life span on them, I know we aren't in them very often. We run some rubber lined impellers though not many.
Our warehouse has a mini telehandler. I love borrowing it, it's handy till you try to do dumb things. You could always throw a hitch on the back and make some sort of work bench/ tool trailer.
