Centrifugal Pump · Pumps
Centrifugal pumps are designed to efficiently transfer fluids through high-pressure impellers and volutes. Flowserve's SIHI ZTN model is specifically engineered for marine applications, handling thermal oil and hot liquids with precision. This electrically driven centrifugal pump ensures reliability in demanding thermal oil service environments. Common issues include mechanical seal leakage at elevated temperatures, bearing overheating due to thermal growth, casing gasket failures, and misaligned couplings. Maintenance routines should focus on checking alignment during operation, monitoring seal leakage and bearing temperatures closely, and inspecting seals and bearings during thermal oil system maintenance. High-temperature resistant components are recommended for optimal performance in this harsh application.
