Technical questions about the FBCN 200-315 centrifugal pump.
FBCN large-capacity models do not have individual physical dimensions published in the standard technical manual. Each project receives dimensional drawing, project-specific performance curve and material selection through direct consultation with FB Bombas engineering.
