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.

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.

Fixed-Flow Air-Powered Vacuum Pumps
Also known as venturi pumps, these compressed-air-powered pumps are commonly used in vacuum packaging, pick-and-place operations, and end-of-arm robotic tooling. They have no seals or moving parts that can wear down or overheat, and they don’t require lubrication, so there's no downtime for maintenance. The compact body allows inline installation close to your vacuum point. Maximum flow rate is the rate at which air is pumped before a vacuum is created. Flow rate steadily decreases as the pump generates the vacuum. The larger the tank, the longer it will take to form a vacuum. Tube and fitting ID will also affect flow. A higher maximum vacuum value indicates a stronger vacuum.

Adjustable-Flow Air-Powered Vacuum Pumps
Use the rotating diffuser to alter flow rate. Also known as venturi pumps, these compressed-air-powered pumps are commonly used in vacuum packaging, pick-and-place operations, and end-of-arm robotic tooling. They have no seals or moving parts that can wear down or overheat, and they don’t require lubrication, so there's no downtime for maintenance. The compact body allows inline installation close to your vacuum point. Maximum flow rate is the rate at which air is pumped before a vacuum is created. Flow rate steadily decreases as the pump generates the vacuum. The larger the tank, the longer it will take to form a vacuum. Tube and fitting ID will also affect flow.

High-Efficiency Fixed-Flow Air-Powered Vacuum Pumps
A multistage design generates a high vacuum flow with less air consumption than other air-powered vacuum pumps. Also known as venturi pumps, these pumps are commonly used in vacuum packaging, pick-and-place operations, and end-of-arm robotic tooling. They have no seals or moving parts that can wear down or overheat, and they don’t require lubrication, so there's no downtime for maintenance. The compact body allows inline installation close to your vacuum point. Maximum flow rate is the rate at which air is pumped before a vacuum is created. Flow rate steadily decreases as the pump generates the vacuum. The larger the tank, the longer it will take to form a vacuum. Tube and fitting ID will also affect flow. A higher maximum vacuum value indicates a stronger vacuum.

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.
