About Vacuum Pumps

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.

Electric High-Vacuum Pumps
Achieve powerful vacuum and continuous flow for applications such as vacuum drying, solvent evaporation, and distillation. 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.

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.

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.
