Compact. Efficient. Engineered for Reliable Vacuum Generation.
SED’s Jet Ejector is a high-performance, non-mechanical vacuum-generating device designed to create and maintain vacuum conditions by harnessing the kinetic energy of a motive fluid - typically water. Through precision-engineered hydrodynamic nozzles, it converts pressure energy into high-velocity streams that entrain air, vapors, or non-condensable gases (NCGs), effectively removing them from the system.
Built for durability and efficiency, SED Jet Ejectors provide a low-maintenance, energy-efficient alternative to mechanical vacuum pumps, making them ideal for industrial processes requiring dependable, continuous vacuum performance.


How It Works
The SED Jet Ejector operates on the principle of momentum transfer:
Motive Fluid Acceleration
Entrainment of Secondary Fluid
Mixing & Compression
Vacuum Creation & Discharge
This simple yet powerful mechanism ensures smooth, silent, and maintenance-free vacuum generation.
Key Advantages
Compact Design with Fast Evacuation
Compact form factor allows easy installation even in space-constrained areas while enabling rapid system startup and vacuum stabilization.
Hydrodynamically Designed Nozzles
Specially engineered jet nozzles amplify the suction effect, ensuring efficient entrainment of gases and reduced motive fluid consumption.
Customized Tailpipe & Flow Geometry
Each ejector is optimally designed for its specific gas load and process conditions, ensuring consistent pressure recovery and smooth discharge flow.
Maintenance-Friendly Configuration
Includes hinge-type top covers and hand-hole access, simplifying cleaning, inspection, and servicing-minimizing downtime and operational effort.
Non-Mechanical & Energy Efficient
No moving parts, no lubrication, and minimal power usage result in high reliability and low operating costs.
