Marine Vortex Pump

Overview

The vortex pump is a specialized pump type based on centrifugal force and vortex flow principles, designed for efficient handling of gas-liquid mixtures, particle-laden fluids, or volatile media. Its non-clogging and cavitation-resistant features make it ideal for challenging marine applications such as wastewater transfer and aerated liquid processing, particularly suited for low-flow, high-head scenarios compliant with ISO standards for marine pumps.

Applications

(1)Bilge Wastewater Transfer:

    Handles oily wastewater and solid residues (MARPOL Annex I compliant).

(2)Ballast Water Emergency Drainage:

    Self-priming lift of 6-8 m for rapid response during main pump failure.

(3)Foam Firefighting Systems:

   Steady delivery of aerated foam mixtures (SOLAS Ch.II-2 compliant).

(4)Cooling Water Circulation:

    Resists seawater corrosion and minor sediment abrasion.

Performance Specifications

Key Advantages

(1)Vortex Impeller Design:

    Open impeller (radial straight vanes) creates annular vortex channels, enhancing pressure via centrifugal and vortex forces.

    Allows passage of solids ≤15 mm and gas-liquid mixtures with ≤30% gas content.

(2)Non-Clogging Capability:

    Wide flow channels (impeller-casing gap ≥5 mm) prevent jamming from fibers or grit.

    Self-cleaning design for heterogeneous fluids like sludge or sewage.

(3)Cavitation Resistance:

   Separated low/high-pressure zones minimize bubble collapse impacts.

   Impeller materials: Brass or hardened cast iron for extended durability.
