The objective of this article is to share industry experience related to the reliability challenges with vertically suspended molten sulfur pumps. Due to the operating temperatures and the unique chemical properties of sulfur, several operational and reliability challenges are inherently present across the industry. The following will discuss common pump field troubles reported by operations, pump failure modes, and case studies that demonstrate typical failure modes and mechanisms. Vertically suspended molten sulfur pumps are used in oil and gas facilities to transfer molten sulfur from melting plants. Both horizontal and vertically suspended pumps cover the broad variety of molten sulfur
