Self-Priming Oil Transfer Pump Selection for Petrochemical Projects
A self-priming oil transfer pump should be selected from the actual liquid and transfer system, not from a generic fuel label. Identify every product to be handled, density, viscosity at minimum and maximum temperature, vapor pressure or volatility, solids, lubricity, corrosiveness, flash-point information, required flow, static lift, pipe losses, discharge pressure, duty cycle, hazardous-area classification, seal requirements, and cleaning or changeover method. Self-priming describes the pump's ability to evacuate air from a correctly arranged suction line after initial filling; it does not...
