Diaphragm vacuum pumps – all Conditions

Diaphragm vacuum pumps are getting more and more standard for little to medium size applications as an alternative to oil-sealed rotary vane pumps.

Diaphragm pumps will be very low maintenance and quiet.

Because of the method of the operation, the materials of construction can be selected for maximum corrosion resistance with only slight compromises in performance, and no compromises in diaphragm lifetime.

It is best to decide on a pump that generates superior flow rates at operating vacuum levels, to provide fast pump downtimes and vapor transfer.

Typical diaphragm lifetimes for these pumps range from 10,000 to 15,000 hours that’s years in many applications!

Traditionally, diaphragm pumps, when employed in laboratory applications, were relegated to the menial lab tasks such as filtration, due to their lack of performance and chemical compatibility.

Modern multi-stage diaphragm pumps will offer vacuum levels throughout the complete rough vacuum vary (atmosphere to below one mbar/torr) providing vacuum levels appropriate for several tasks.

Standard models will perform degassing of liquids, and even be used as backing pumps for a wide range turbomolecular pumps.

Chemistry-design models can perform nearly any evaporative task, except room temperature evaporation of very high boiling point solvents, such as DMSO or ethylene glycol.

Pumps with the high flow at operating vacuum supply the advantage of having the ability to control while not a chilly entice to boost their performance.
