About Vacuum Pumps

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.

Oil-Free Electric Vacuum Pumps

Since these pumps don't require lubrication, there’s no risk of oil contamination. 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 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.

Style B pumps are often used for aeration, leak detection, and liquid-level control.

Style C pumps withstand harsh operating conditions. Use to service machinery and refrigeration and circulation systems.

Portable Oil-Free Electric Vacuum Pumps

These pumps weigh only 16 pounds and have a handle, so they're convenient for on-site sampling, atomizing, and vacuum filtration. They're also for use in pressure applications up to 60 psi. Since they don't require lubrication, there’s no risk of oil contamination. 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.

Repair kits include filter/muffler components, a gasket, a leaf valve, limiters, and an O-ring.

Electric Ultra-High-Vacuum Pumps

Achieve vacuum levels up to 1 x 10 ^-12 torr with these ultra-high-vacuum pumps. Each unit includes two pumps—a diaphragm pump and a turbomolecular pump—that work together to create extremely high levels of vacuum in your chamber. The turbomolecular pump meets IP54 for protection in damp and dusty environments. Units are compact, so they fit on top of a workbench or table.

Pumps are ready to use as soon as they’re plugged in and connected to a chamber. Since they don’t use oil, they won’t introduce contaminants into your system. They hardly vibrate, minimizing interference with sensitive instruments and measurement devices.

Pumps with claw-clamp intake connections require a ring and four double-claw clamps (all sold separately) to connect to other components. Claw-clamp connections are also known as ISO-K fittings. These pumps include a gauge with quick-clamp connections, which requires a quick clamp and a ring (both sold separately) to connect. Quick-clamp connections are also known as KF fittings.

Pumps with flanged intake connections and the included gauge each require a gasket (sold separately) to connect to your chamber. Flanged connections are also known as CF fittings.

Robot-Arm-Mounted Electric Vacuum Pumps

Generate the suction you need to power end-of-arm tools, such as vacuum cups and grippers, without using an installed vacuum system. These pumps, also known as venturi devices, connect to any compressed air source and come with all the electrical connections you need to start lifting or moving objects. They’re curved and have a foam mounting pad that fits collaborative robot arms. Use the hook-and-loop straps to secure them in place—close to your tools, but out of the way.

These pumps have a vacuum switch that uses analog and PNP digital feedback to send information about the pump’s vacuum level to your controller. The switch has an LED display that shows the vacuum setting and status. Push buttons on the pump let you set and change the vacuum setting. An integrated solenoid valve controls the air flow to your tools.

Vacuum pumps with a discharge tube have an additional integrated solenoid valve that creates a burst of air for removing parts that may not drop when the air flow stops, such as those with adhesive on them.

Vacuum pumps with M8 plug will work with FANUC CRX and Universal Robots models. They include a USB flash drive with software for Universal Robots, called URCap, that plugs into your teach pendant to program the pump.

Adjustable-Flow Air-Powered Vacuum Pumps

Vacuum Pump

Replacement Muffler

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.
