Metal Liquid-Powered Jet Pumps

Powered by liquid, use these to pump a second liquid or to produce emulsions, elevate water, and transport grains and other small particles. When high-pressure liquid enters the intake, it creates suction that draws a second liquid into the pump body and discharges a pressurized blend of the two. The discharge pressure is greater than the suction flow but lower than the intake pressure. They have no moving parts or seals, eliminating downtime for lubrication and repairs. They're also known as eductors, ejectors, and injectors.

Note: Liquid suction flow rate is calculated using water at 100 psi with no feet of discharge head.

Bronze Housing—Bronze is more corrosion resistant than steel.

316 Stainless Steel Housing—316 stainless steel pumps are the most corrosion-resistant metal option.

Chemical-Resistant Plastic Liquid-Powered Jet Pumps

Made from PVC, these pumps are highly corrosion resistant and lightweight. Use them to produce emulsions, elevate water, and transport grains and other small particles. When high-pressure liquid enters the intake, it creates suction that draws a second liquid or gas into the pump body and discharges a pressurized blend of the two. The discharge pressure is greater than the suction flow but lower than the intake pressure. They have no moving parts or seals, eliminating downtime for lubrication and repairs. They're also known as eductors, ejectors, and injectors.

Note: Liquid suction flow rate is calculated using water at 100 psi with no feet of discharge head.
