Oil-Free Electric Vacuum Pumps
 C |  A |

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.
Repair kits include a replacement diaphragm.

Portable Oil-Free Electric Vacuum Pumps
These pumps weighs 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.

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.
