Ballast Eductor & Bilge Eductor
Ballast Eductors & Bilge Eductors are Liquid Eductors specifically designed for the Shipbuilding Industry. Based on the jet venturi principle the Ballast Eductor & Bilge Eductors are able to suck liquids in and pump them out of the outlet.
This ability is put to use in draining and filling of ballast tanks, draining and filling of bilge areas.
A Conventional Mechanical Pump requires Electrical Energy for its operation, similarly Ballast Eductors / Bilge Eductor require High Pressure Liquid flow, they utilize the energy stored in the pumped liquid. The Operation of Ballast Eductors & Bilge Eductors does not involve any moving parts and is completely dependent on the internal geometry. In most Installations Ballast Eductors & Bilge Eductors utilize Liquid from the Ballast Headers or from the vessel’s Fire Fighting system.
Our Ballast Eductors are successfully catering to de-Ballasting operations, pumping Crude and evacuating Bilges on Ships throughout the World.

Frequently asked questions (FAQs) about Ballast Eductors:
A ballast eductor is a type of eductor pump that uses a high-pressure fluid (typically water) to entrain and pump another fluid (such as seawater or ballast) from one location to another. It operates on the principle of the Venturi effect, where the high-velocity flow of the motive fluid creates a low-pressure area, drawing in and mixing with the entrained fluid.
A ballast eductor works by passing a high-pressure fluid (often seawater) through a nozzle at high velocity. This creates a vacuum or low-pressure zone around the nozzle, drawing in the fluid (ballast or seawater) from the surrounding area. The mixed fluid then exits the eductor through a diffuser, where pressure is recovered and the fluid is discharged.
Ballast eductors are commonly used in marine applications for transferring ballast water between tanks on ships or offshore platforms. They are also used in industrial processes where fluid transfer or mixing is required without the need for mechanical pumps or electricity.
Ballast eductors are simple in design, have no moving parts, and can handle solids or particles in the fluid being transferred. They are also easy to install and operate, requiring minimal maintenance compared to mechanical pumps.
One limitation of ballast eductors is their efficiency, which can be lower compared to mechanical pumps for certain applications. They are also dependent on a high-pressure fluid source (such as seawater) for operation.
Sizing a ballast eductor involves determining the required motive fluid flow rate and pressure drop across the eductor to achieve the desired flow rate and pressure for the entrained fluid (ballast or seawater). Factors such as inlet pressure, discharge pressure, and specific application requirements influence the sizing process.
Ballast eductors generally require minimal maintenance due to their simple construction and lack of moving parts. Periodic inspection and cleaning of nozzles, diffusers may be necessary to ensure optimal performance.
Ballast eductors are typically designed to handle liquids, such as water or ballast, and are not suitable for gases or highly viscous fluids. They can handle fluids with solids or particles as long as they do not cause blockages in the nozzle or diffuser.
Ballast eductors can vary in design based on the specific application and fluid transfer requirements. Variations include different nozzle configurations, materials of construction, and sizes to accommodate varying flow rates and pressures.
