High-pressure multistage centrifugal pumps deliver reliable, high-head liquid transfer by combining multiple impellers on a single shaft. Designed to produce significantly higher discharge pressures than single-stage pumps, these units are suitable for demanding industrial applications where space-efficient, continuous high-pressure flow is required.
Key features
- Multistage design: two or more impellers staged in series to increase head while maintaining a compact footprint.
- High head capability: multistage versions exceed 125 m total head; single-stage variants are generally limited to about 125 m.
- Robust construction: modular inlet, intermediate and outlet sections are joined by a tie-rod (pull rod) for simplified assembly and maintenance.
- Materials: available in cast iron or stainless steel to match fluid compatibility and corrosion requirements.
- Standard components: impellers, pump body, shaft, bearings, sealing rings or stuffing box, tail cover and mounting arrangements.
Benefits for industrial users
- Produces high discharge pressure for long-distance transfer, high-head irrigation, boiler feed, or process systems.
- Modular construction simplifies repairs and spares management — individual stages or seals can be serviced without replacing the entire unit.
- Vertical or horizontal configurations allow installation flexibility to suit site footprints and piping layouts.
Typical applications
- Petroleum and petrochemical plants
- Chemical processing and reagent transfer
- Mining dewatering and high-head services
- Food, beverage and pharmaceutical process lines (with appropriate materials and seals)
- General mechanical and industrial water services
Selection guidance
When requesting a quote or specification, provide required flow (m3/h or L/min), total head (m), operating temperature, pumped fluid properties (viscosity, solids content, corrosiveness), preferred orientation (vertical/horizontal), and material preference (cast iron or stainless steel). This information enables sizing, impeller staging and seal selection to match performance and reliability targets.
For procurement: available in model families D, DG and CDL (manufacturer model/MPN references). Technical data sheets and performance curves are recommended to confirm stage count, rotational speed and efficiency for your operating point.
