Multistage Centrifugal Pump — Model Range

Choosing an HS or TS Multistage Centrifugal Pump

A multistage centrifugal pump stacks several impellers in series on one shaft. Each stage adds pressure, so the pump can deliver higher head than a single-impeller pump of similar size while staying compact. The HS and TS series are close-coupled, space-saving pumps for pressure boosting from city mains or private water systems, with corrosion resistant materials on all wetted parts.

The TS series runs from the 0.37 kW TS400 to the 3.7 kW TS3700. The TS400 and TS800 have 1 inch connections, while models from 1.5 kW have 2 inch connections and are available in single and three-phase versions. At 50Hz the TS range delivers up to 34 m head and 250 L/min; at 60Hz the TS3700 reaches 50 m and 270 L/min. TS pumps can handle both plain and salt water and lift water up to 7.6 m on the suction side. The HS series is smaller, with the 0.37 kW HS400 and 0.75 kW HS800, both single phase with 1 inch connections, up to 110 L/min at 50Hz and suction lift up to 6 m.

Both series shut off when water temperature exceeds 55°C (130°F), which protects against dry running, and single-phase motors include thermal overload protection. Size the pump on the flow and pressure needed at the highest outlet.
