EJECTOR
About the
SUMP EJECTOR
A sump ejector is a device that pumps liquid accumulated in a sump and discharges it elsewhere. The motive fluid can be freely selected from steam, air, liquid, and other options.
Advantage
Usable in High-Temperature and Corrosive Environments
- Heat-resistant and corrosion-resistant materials applicable
- Feasible to be used for high-temperature steam, waste liquids, and chemical processing
Capable of Transferring Fluids Containing Sludge, Sediment, and Foreign Matter
- Possible to discharge liquids containing sludge, fibers, and solids without clogging
- Suitable for drainage wells, sludge tanks, tank bottom cleaning, and similar applications
Easy Installation and Utilization of Confined Spaces
- Easily installable in underground wells and beneath compact equipment
Operates Without Electricity
- Operates with compressed air or steam only, without electric motors or rotating parts
- Feasible to be used in areas where electrical installation is difficult
How it works
The high-pressure injection action of the motive fluid creates a vacuum inside the ejector, drawing in suction fluid and discharging both fluids under pressure. As the suction fluid is pumped, the sump level drops to the selected level gauge point. No further pumping action occurs until the sump refills to the operating level.
Use Cases
Chemical/Refining Plants
Removal of sludge and sediment from reactor or storage tank bottoms
Power Plants
Boiler drains, condensate discharge
Marine/Offshore Plants
Removal of bilge water from ship bottoms or tanks
Pharmaceutical/Food Plants
Floor water around sanitary facilities, drainage well cleaning
Water/Wastewater/Environmental Facilities
Sludge wells and contaminated water tank drains at wastewater treatment plants
