Horizontal, axially split multi stage pump , double volute, with overflow return channels, stiff shaft supported by internal, product lubricated sliding bearings, opposed side suction and discharge nozzles, in bottom half of the casing, dismantling without breaking pipe lines, mechanical seal (single, double, tandem).
BB3 pumps design according to API610 with these advantages:
Control of all clearances and setting due to inner case design, only one external high pressure seal, high compensation of hydraulic axial thrust, small axial thrust bearing, lower leakage loss through piston, resulting in higher efficiency, dynamically balanced rotating assembly, higher critical speed due to the supporting effect of centre stage piston, impeller shaft and wear parts remove as complete unit, easy to inspect.
