Liquid Vacuum Ejector
Liquid jet Vacuum ejector are simple devices that operate on the basis of the jet Venturi principle.
Liquid jet Vacuum ejector typically have 3 connections
- 1. High Pressure(HP) Liquid Inlet
- 2. Gas Suction
- 3. Outlet
During operation Liquid Vacuum Ejector is able to create a pressure differential across its Suction and outlet. Liquid jet Vacuum ejectors utilize the energy in pumped liquid entering from the HP liquid inlet to create this pressure differential.
This enables Liquid Vacuum Ejector to be used for creating vacuum at its suction. The low pressure allows the Vacuum ejector to suck gases through the suction. The suction gas mixes with the HP liquid inside the Ejector and gets pumped out from the Outlet. The discharge contains the mixture of HP liquid and suction gas.
This phenomenon allows the Vacuum Ejector to be used for creating vacuum or for evacuation applications.
Typical Applications
- Process Vacuum
- Gas Evacuation
- Liquid Degassing
- Gas Micro-Bubbling.
Features Of Vacuum Ejector
- Large range of standardized models – ensures accurate fit for your application while ensuring shorter delivery time and low costs
- Delivers very high vacuum upto the motive liquid vapour pressure. (For ejector operated with water @ 30°C, ultimate vacuum upto 30 Torr or 40mbar can be obtained).
- Can operate with wide range of motive liquid pressure from 2.5 bar(a) to 6 bar(a).
- Excellent intermixing of liquids and gases can be obtained at outlet.
- Availability in multiple type of end connections – Flanged, Threaded
- Available in a large variety of materials
| Metallic | Non Metallic |
|---|---|
| Stainless Steels SS 304 / SS 316 | PVC (Poly-vinyl-chloride) |
| Bronze | PP (Poly-propylene) |
| Duplex & Super Duplex Stainless Steel | |
| Exotic metals (Hastelloy, Inconel, Titanium) |
Benefits Of Liquid Vacuum Ejector
- Static Device without any moving parts – ensure long reliability and maintenance free operation.
- Tolerate entry of liquids & solids particles into the ejector – avoids abrupt breakdowns.
- Silent Operation
- Non sparking operation – can be safely used in hazardous & flammable areas
- Manufactured in multiple materials – allows using the most cost-effective & chemically compliant materials for the application.
