Hopper Ejector & Eductor
Hopper Ejector Systems consist of a skid based unit containing a Hopper and a Liquid Eductor.
The Outlet of the hopper is connected to the suction inlet of the Liquid Eductor
During operation Hopper Ejectors are able to create a pressure differential across its Suction and outlet. Hopper Ejectors utilize the energy in pumped liquid entering from the HP liquid inlet to create this pressure differential.
This enables Hopper Ejector to be used for creating low pressure at its suction. The low pressure allows the Hopper Ejectors to suck the material Liquid Solids Ejector (liquids, solids or liquid solid-mixture) from the hoppers. The sucked material mixes with the HP liquid inside the eductor and gets pumped out from the Outlet. The discharge contains the mixture of HP liquid and the material in the hopper.
This phenomenon allows the Hopper Eductor to be used for sucking and pumping Powders, granules and any other solid particles.
Hopper Eductor can develop significant head at the outlet which enables slurry to be pumped across 100s of metres of pipeline.
The hoppers are fitted with an inbuilt spray system to ensure smooth flow of material from the Hopper to the Ejector.
Typical Applications
- Powder Dosing
- Lime Dosing
- Chemical Dosing
- Powdered Activated Carbon (PAC) Dosing
- Granular Activated Carbon (GAC) Dosing
Features Of Liquid Solids Ejector
- Skid based unit consisting of a Hopper, Ejector, Spray System and mounting Frame
- Standardized Hopper sizes ranging from 0.1m3 to 2.5m3

Benefits of Hopper Ejector & Eductor
- Hopper allows material loading to be a one time activity.
- Functions as both – Dosing Ejector , Dilution Ejector.
- Wear Resistant Internals – ensures prolonged operation and long operating life
- Large Internal passage area – avoids choking during operation.
- Static Device without any moving parts – ensure long reliability and maintenance free operation.
- 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.
