Vertical Turbine Pump Technology

Vertical turbine pumps represent the pinnacle of centrifugal pump design for high-head, high-capacity wastewater applications. These sophisticated pumping systems feature multiple impellers mounted on a vertical shaft within a series of diffuser bowls, creating a multi-stage configuration that efficiently generates the high pressures needed for deep well pumping and high-head lift stations.

Unlike traditional centrifugal pumps that rely on a single impeller, vertical turbine pumps utilize multiple stages to incrementally increase pressure with each stage. This design allows them to achieve total dynamic heads of several hundred feet while maintaining excellent efficiency across a wide operating range. The vertical configuration minimizes the pump's footprint while maximizing performance.
