A single-stage centrifugal pump uses one hydraulic stage, while a multistage pump uses successive stages to add head through the assembly. The appropriate choice depends on the required flow, head, liquid, installation and operating range. More stages do not automatically mean more flow, higher efficiency or better suitability. Select the duty from verified performance data, then compare mechanical and service requirements. This guide addresses clean-water transfer and boosting without assigning undocumented pressure, stage counts or operating limits to a Borra product. Separate...
