Two-stage centrifugal pumps are used in applications where higher head is required. They ensure more reliable, high efficiency process and lower operating costs instead of serial pumping system.
Benefits
Centerline support for reduced thermally induced misalignment
BBT-D double-suction impeller for low Net Positive Suction Head (NPSH)
First critical speed is well above operating speed range for smooth operation
Casing designed for 2x API 610 nozzle loads for freedom from piping distortions
Grouted or ungrouted, 1x or 2x nozzle load baseplates for reduced installation cost
Applications
Unit charge
Clean and lightly contaminated liquids
Viscose liquids
Atmospheric or vacuum bottoms retrofits where Net Positive Suction Head Available (NPSHa) is limited
Fractionator bottoms
Coker heater charge
Boiler feed booster
