Can silicon nitride bushings be used with pumps for fluorine-containing wastewater, when the concentration is below 5 percent?
Thread Content
Does a silicon nitride bushing react with wastewater containing 3% fluoride?
Is it on the K-type seal of the UHB pump? Silicon nitride will do in a pinch. . .
Yes, 90 degrees temperature – is it usable?
UHB pumps are generally made with an ultra-high molecular weight material as the lining; they can’t withstand prolonged use at 90 degrees

If there are none or only trace amounts, it is recommended to use an IHF fluorocarbon-lined centrifugal pump; for the seal, use pressure-free sintered silicon carbide, which is more reliable than UHB.
