QY Self-priming gas-liquid vortex pump

High-efficiency self-priming gas–liquid vortex pump designed to inhale, mix, dissolve and deliver gas-enriched liquids without external compressors or ejectors. The pump uses the high-speed impeller to entrain and disperse gas into liquid under pressure, producing highly dissolved solutions (typical dissolution efficiency 80–100%) and eliminating the need for large pressurized gas tanks or expensive contact towers.

Key features

• Self-priming suction: negative-pressure inlet draws gas directly into the liquid stream; no air compressor or atmospheric ejector required.
• Integrated gas–liquid mixing: high-speed rotating impeller provides pressurized mixing and fine dispersion for rapid dissolution.
• High dissolution efficiency: typically 80–100% dissolved gas content in the delivered liquid.
• Gas–liquid ratio: approximately 1:9 (inspiratory capacity ~8–10% by volume); intake capacity can be increased by connecting pumps in series.
• Combined functions: inhalation, mixing, dissolution and delivery in a single unit — reduces system complexity and footprint.
• Compact and cost-efficient: simplifies installation, lowers operating and maintenance costs compared with traditional pressurized systems.

Typical applications

• Preparation of ozone water and oxygen-rich water
• Gas–liquid mixing and agitation, process circulation and pressurization
• Water treatment, pure water systems, and food spray/treatment applications
• Transfer of thin, clean, low-viscosity liquids or liquids containing fine suspended solids

Operating limits & hydraulics

• Liquid temperature range: -15 °C to 120 °C
• Self-priming (NPSH) height: approximately 9 m
• Inlet/outlet orientation: suction inlet horizontal; discharge outlet vertical

Benefits for industry

• Streamlines dissolved-gas production at point-of-use
• Avoids large pressurized dissolution vessels and complex process equipment
• Reduces site requirements, CAPEX and OPEX while improving process flexibility

Notes

• Select materials and model variants appropriate for your liquid chemistry, temperature and solids content. Consult pump curves and NPSH requirements when specifying system layout and pump configuration.
