Liquid Ejectors
Liquid Ejectors are simple devices that operate on the basis of the jet Venturi principle.
Liquid Ejectors typically have 3 connections
- 1. High Pressure(HP) Liquid Inlet
- 2. Suction
- 3. Outlet
During operation Liquid Ejectors are able to create a pressure differential across its Suction and outlet. Liquid Ejectors utilize the energy in pumped liquid entering from the HP liquid inlet to create this pressure differential.
This enables Liquid Ejectors to be used for creating vacuum / low pressure at its suction. The low pressure allows the Liquid Ejectors to suck liquids through the suction. The suction liquid mixers with the HP liquid inside the Ejector and gets pumped out from the Outlet. The discharge contains the mixture of HP liquid and suction liquid.
This phenomenon allows the Liquid Ejectors to be used for sucking and pumping Water, chemicals, acids, alkalis, slurries, sludges, etc
The amount of suction liquid sucked and the head difference between Suction and Outlet depends upon the size of the Liquid Ejector and the internal construction. Further the operating flows can be controlled by regulating the HP Liquid, Suction & Outlet Pressures.

Benefits of Liquid Ejectors
- Static Device without any moving parts – ensure long reliability and maintenance free operation.
- Tolerate entry of solids particles into the ejector – avoids abrupt breakdowns.
- Small & compact size – allows installation in tight spaces & difficult to access areas.
- 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.
