Water Aspirator Pumps

Create vacuum suction quickly—by running water through the body of these aspirator pumps, you can draw liquids and gases in through the side arm. They’re often used in labs for vacuum filtration and picking up spilled liquids. Made of HDPE, their housing resists corrosive chemicals such as filtrates and acids. Run water through these pumps by connecting them to your faucet; they’re commonly known as faucet aspirators. They have a removable barbed tube connector that you can leave attached to your vacuum tubing and connect to the pump only when you’re using it. To prevent water backflow, there’s an internal check valve. These pumps come with polyethylene tubing to discharge water and chemicals without splashing; the tubing is chemical resistant.

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.
