Diaphragm pumps

These mechanical diaphragm pumps function without oil. They are easy to operate, use no water and generate neither wastewater nor used oil. These pumps are used for evacuating or pumping gases between containers in chemistry or physics laboratories and are extremely versatile.

• Available in aluminium or chemical
• Large selection of final pressure and pump capacities, high pump volume capacities even at low pressures
• Maintenance-free drive unit, constructed for easy maintenance, diaphragm and valves are easy to replace
• Very quiet, low-vibration
• Optimised service life of diaphragms and valves (normally over 10000 operating hours)

Aluminium versions
Parts that come into contact with media are made from aluminium, FPM, PE, PBT or similar. Broad range of vacuum-generating applications in the laboratory and in industry with non-aggressive gases, e.g. vacuum filtration, vacuum stream degassing and vacuum impregnation.
Exceptionally long-lasting FPM valves.
Large cylinder input volume with minimal dead space ensures high input power.
Optimised, extremely flexible FPM double diaphragms with fabric reinforcement; good operating safety and diaphragm service life.
Available as one-, two-, three- or four- stage pumps, please contact your local Avantor sales office for details.
Compact construction.

The gases and vapours that are pumped only come into contact with fluorinated plastics, with outstanding chemical resistance properties. Typical applications include, for example, pumping chemically active vapours.
