Anyone experience excessive erosion wear (pumping a heavy sand slurry) on slurry pump suction liners. We had been testing a urethane productwith great success, then changed the discharge piping from 20" to 24" diameter and reduced our suction liner wear from 52 weeks to 4 weeks. Process conditions have not varied that much. Any comments would be appreciated. Pumping a slurry density of 1.4 gms/ml, 16000 usgpm, discharge pressure of 300 psig.
