Submersible Dewatering Pump Selection for Construction and Drainage

A submersible dewatering pump is selected by matching the required drawdown flow, total dynamic head, solids and abrasiveness, minimum operating depth, cable and power supply, and the site's duty cycle. It should not be chosen from outlet size or motor power alone. Establish how fast water enters, where it can legally discharge, and how the water level and hose route will change. Then plot normal and worst-case duties on a certified pump curve, verify motor loading and cooling, and specify level controls,...

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...
