High-temperature sulfur pump; toxic gases are present inside the tank, to prevent any leakage of these gases
Thread Content
Hello everyone, the medium present at the customer’s site is liquid sulfur, with a temperature of around 150°C and a pressure range of -20 Kpa to 50 Kpa; there are toxic gases inside the tank. Previously, our company used submersible pumps combined with dry gas seals to keep the gas inside the tank under pressure with nitrogen, thereby preventing toxic gases from leaking – this process resulted in nitrogen consumption. It performs well in actual use. But now the customer wants to switch to mechanical seals and avoid using nitrogen; the seal manufacturers recommend the PLAN53B model. I’m not sure if this requirement can be met, or if anyone here has any good suggestions for a flushing solution? The main requirement is to ensure that no gas leaks from the tank~~
Hello, do you think 53B is feasible?
