Industrial Ozone and Oxygen Mixing Pump
1. Product Overview
ClearFlow Gas-Liquid Mixing Pumps are designed for efficient gas and liquid mixing, gas dispersion, and gas dissolution in industrial water treatment systems. They can draw air, oxygen, or ozone into the pump through the suction side and mix it with water through a multi-blade impeller.
During operation, the impeller generates strong shear and turbulent mixing forces, dispersing the incoming gas into fine bubbles and promoting gas-liquid contact under pressure. This integrated process allows the pump to perform gas intake, mixing, and pressurized delivery in one unit, without requiring a separate air compressor or gas injector for suitable applications.
Featuring a compact structure, self-priming gas intake, and stainless steel pump head, ClearFlow gas-liquid mixing pumps are suitable for ozone water mixing, oxygen dissolution, dissolved air flotation (DAF), aquaculture oxygenation, and wastewater treatment.
When combined with a gas dissolving tank, the pump can serve as a key component in compact ozone mixing, gas dissolution, and nanobubble generation systems.
2. Working Principle of Gas-Liquid Mixing Pumps
A gas-liquid mixing pump uses a high-speed rotating impeller to mix gas and liquid within the pump chamber.
The working process generally includes the following steps:
Step 1: Water Intake
Water enters the pump through the inlet and is transported into the mixing chamber by the impeller.
Step 2: Gas Self-Priming
Air, oxygen, or ozone is introduced through the gas suction port. The pump creates the required suction conditions to draw gas into the liquid flow without a separate compressor or injector under suitable operating conditions.
Step 3: Gas-Liquid Mixing
The multi-blade impeller generates high-speed shear forces and turbulent flow, breaking the incoming gas into smaller bubbles and distributing them throughout the water.
Step 4: Pressurized Delivery
The gas-water mixture is discharged under pressure. When connected to a dissolving tank, the system provides additional gas-liquid contact and pressure conditions to promote gas dissolution.
Step 5: Downstream Treatment
The mixed gas and water can be supplied to downstream treatment processes, including ozone oxidation, oxygenation, dissolved air flotation, and other water treatment applications.
The actual bubble size and gas dissolution efficiency depend on pump operating conditions, gas supply, water quality, system pressure, and the configuration of the downstream equipment.

3. Key Features and Advantages
