About Vacuum Pumps

Oil-Free Electric Vacuum Pumps
Generate a vacuum with no risk of oil contamination in your system. These pumps can also create compressed air for powering tools and controlling fluid motion. In vacuum generation, the 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.
Style A pumps withstand harsh operating conditions. Use them to service machinery, refrigeration systems, and circulation systems. As compressors, they can power pneumatic tools.
Style B pumps are often used for air and gas sampling, controlling compressed air flow, and vacuum filtration. They are also suitable for pressure applications up to 18 psi, such as light pick-and-place operations.
Style C and D pumps are often used for aeration, leak detection, and liquid-level control. As compressors, they can apply protective coatings or dispense adhesives in exact amounts.
Threaded connections are secure and leak resistant. They’re ideal for permanent or semi-permanent installations. Barbed connections join quickly and easily in tight spaces with no threading or sealant needed.

Portable Oil-Free Electric Vacuum Pumps
Create a vacuum for on-site sampling, atomizing, and filtration, or generate compressed air for power tools when and where you need it. Since these pumps don't require lubrication, there’s no risk of oil contamination. Their barbed connections join quickly and easily in tight spaces—no threading or sealant needed. In vacuum generation, 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.
Repair kits include filter/muffler components, a gasket, a leaf valve, limiters, and an O-ring.

Oil-Free Electric Vacuum Pumps with Tank
Generate a vacuum on demand with these pumps that come mounted on a 10-gal. ASME code vacuum tank for quick startup. They're often used in vacuum-forming applications, such as product packaging. They need no lubrication, so oil won't contaminate your process. 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.

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.
