Combination of Vacuum System of Steam
Jet Ejector and Liquid Ring Vacuum Pump

Efficient hybrid vacuum technology.
Deeper vacuum, lower energy use.

Combination of Vacuum System of Steam Jet Ejector and Liquid Ring Vacuum Pump

Mazda’s combination system merges the reliability of steam jet ejectors with the efficiency of liquid ring pumps.
A versatile solution engineered for stable vacuum generation under varying load conditions.

Product Overview

Mazda’s Combination of Vacuum System of Steam Jet Ejector and Liquid Ring Vacuum Pump is an advanced hybrid solution designed to achieve deep vacuums with maximum efficiency. The steam ejector provides high-capacity suction at low cost, while the liquid ring vacuum pump enhances vacuum depth and stability, especially under fluctuating load conditions. An inter condenser further optimizes performance by reducing steam consumption and minimizing the load on the pump. With this integration, Mazda delivers a robust, economical, and energy-efficient system ideally suited for demanding industrial applications.

Advantages

Achieves deeper vacuum levels with hybrid design
Energy efficient with reduced steam consumption
Stable operation under varying load conditions
Effective handling of condensable and non-condensable gases
Rugged, low-maintenance construction for long service life
Flexible configuration with inter condensers for higher efficiency

How it Works
Use Cases

Steam Jet Ejector – High-pressure steam expands through a nozzle, creating a low-pressure zone that entrains gases or vapors. The mixture is compressed to an intermediate pressure.
Inter Condenser – Steam is condensed, reducing the load on the liquid ring pump, while only non-condensable gases pass forward.
Liquid Ring Vacuum Pump – Handles the remaining gases, further lowering pressure and ensuring steady vacuum levels, including during startup or low-load conditions.

Power Generation (Steam Turbines, Condenser Systems)

Supports stable vacuum generation in steam turbine and condenser systems, including operation under varying load conditions.

Refineries & Petrochemical Plants

Suitable for industrial vacuum applications requiring reliable performance and continuous operation under varying loads.

Fertilizer & Chemical Industries

Energy recycling in evaporation and concentration processes

Pulp & Paper Production

In multi-effect evaporators, capturing and reusing waste steam after the final effect

Food Processing & Distillation Units

Supports vacuum generation in distillation and other process applications where deeper and stable vacuum is required.

Wastewater Treatment Plants

Used in vacuum-based process applications where reliable handling of gases and vapors is required.
