Diaphragm pumps are oil free, tend to be more resistant to corrosion and are the product of choice for most applications that do not require high vacuum.
Two stage rotary vane pumps use oil, are recommended for applications that require a high vacuum but anything exhausted through them will be exposed to oil.
Combination pumps combine the benefits of diaphragm and rotary vane pumps.
Scroll pumps offer the same high vacuums as rotary vane pumps but are generally variable speed and product exhausted through them are not exposed to oil.
WOB-L piston pumps are a lower cost alternative to diaphragm pumps.

Chemically resistant Please consider the compatibility of the pump required with the intended use. You may wish the pump to be spark proof when working with volatile compounds such as ethanol, or resistant to acids. Please contact us if you require more information on the above.

Inlet trap An inlet trap retains particles and liquid droplets, preventing them from entering the pump where they could affect the vacuum performance.

Ultimate vacuum ( mbar ) mbar is the unit for pressure. The smaller the mbar the more pressure created. User should choose a unit with a lower level than they require

Flow rate at atmospheric pressure ( l/min ) The bigger the flow rate the more work done by the pump.

ATEX compliant Some pumps meet the requirements of ATEX equipment category 3. If this is relevant to your requirement, please contact us for applications support as we also have other units available that can be quoted on a case-by-case basis.

Integral gas ballast valves

A gas ballast valve helps purge out any condensable media from the pump lines (especially useful in chemistry applications) and thus maintains optimal pumping performance. It does this by injecting a precise and small amount of dry and fast flowing air into the pump lines normally between the penultimate and final pumping stages. The fast flowing airstream pushes out the heavier condensate. It is important to be aware that in opening the gas ballast, this will have the effect of reducing the ultimate vacuum performance of the pump, since it is essentially introducing a small leak into the system.

No
Yes

Oil free

Units that show "Yes" do not use oil and therefore remove the risk of oil mist contamination in the output.

No
Yes

Wireless remote control Units that show Yes can be remotely operated from a portable terminal to ensure flexibility in the laboratory.

No
Yes

Suitable for rotary evaporators? Units that show Yes are suitable for use with rotary evaporators.

No
Yes

Suitable for filtration? Units that show Yes are suitable for filtration.

No
Yes

Suitable for filtration distribution? Units that show Yes are suitable for filtration distribution.

No
Yes

Suitable for distillation? Units that show Yes are suitable for distillation.

No
Yes

Suitable for dessication? Units that show Yes are suitable for dessication.

No
Yes

Suitable for use with larger volumes of solvents Some units are supplied with a separator and waste vapour condenser. The separator retains particles and liquid droplets and the waste vapour condenser enables efficient recycling of solvents and active protection of the environment. Both these features make these units suitable for use with larger volumes of solvents.
