Hundreds of impellers on the floor are not a stockpile but consumables
A new factory sent a video and I froze. Hundreds of slurry pump impellers laid out on the floor.
To someone outside the industry it looks like a ten-year stock. In fact it is consumables.
On abrasive slurry an impeller lives from a few weeks to a few months. Sand, ore and ash work like emery. The pump is bought once, but impellers, volutes and liners keep shipping again and again.
