Water Aspirator Pumps

Pick up chemical spills and remove liquids in vacuum filtering systems—these pumps create suction to draw up liquids and gases as water flows through them. They’re made of HDPE and polyethylene, so they won’t break down when exposed to highly corrosive chemicals and acids. The suction end has a barbed tube connector, which attaches to your vacuum tubing. The connector stays attached to your vacuum tubing and connects to the pump when you’re ready to use it again. These pumps also have an internal check valve to prevent backflow.

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 is more corrosion resistant than cast iron.

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.

Steam-Powered Jet Pumps

Use plant steam to pump liquids and gases, prime pumps, and remove fumes. When high-pressure steam 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. Gas suction flow is calculated using steam at atmospheric 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 80 psi steam at 0-40 feet of discharge head.

Bronze is more corrosion resistant than cast iron.

316 stainless steel pumps provide the most corrosion resistance.
