Technical Introduction
Technical Introduction
The KL Series High-Efficiency Ejector uses pressurized working fluid to form a high-speed jet within the ejector nozzle chamber. The high-speed fluid generates a pressure drop, causing the substance to be added (liquid/gas) to be drawn in through the suction port and entrained into the working fluid. After vigorous mixing, the resulting mixture passes through the diffuser section where it decelerates and its pressure increases before exiting through the outlet.
The KL Series Venturi Ejector features high mixing efficiency, a wide operating pressure range, low suction pressure requirements, and low energy consumption. It has been widely applied in various fields including ozone dosing for wastewater treatment, oxygen recovery, flotation, aeration oxygenation, vacuum extraction, aquaculture, and more.

Technical Advantages
Technical AdvantagesHigh Mixing Efficiency
Based on the Venturi jet principle, the high-speed jet fluid and suction medium undergo vigorous mixing within the chamber, achieving mixing efficiency far superior to conventional stirring methods
Wide Operating Pressure Range
Stable operation across a wide pressure range of 0.2~0.8 MPa, adaptable to various operating conditions
Low Energy Consumption
Low suction pressure requirement — only a certain working water flow and pressure are needed to complete suction, with no additional power equipment required
Maintenance-Free Design
No moving parts, consistent long-term performance, reliable operation, and convenient maintenance management
Easy Installation
Flange connection with flexible arrangement, allowing free adjustment of installation position and angle according to site conditions
Low Noise, Pollution-Free
The jetting process produces no mechanical operation noise — quiet operation with no secondary pollution
Long Service Life
Simple and robust structure with optional corrosion-resistant materials, long service life, and low total investment cost
Broad Applicability
Capable of suctioning both gases and liquids, widely used in ozone dosing, flotation, aeration, oxygen recovery, vacuum extraction, and other applications
