How Diaphragm Pumps Work

A diaphragm pump uses a flexible membrane that flexes back and forth to draw in, compress, and discharge gas. Because the process gas never contacts oil or sliding metal surfaces, the pump runs completely oil-free and resists contamination. This makes VACUUBRAND diaphragm pumps ideal for applications where sample purity and clean vacuum matter most.

Key Benefits

VACUUBRAND diaphragm pumps offer oil-free operation, low noise and vibration, chemical-resistant wetted materials, and long service life with minimal maintenance. Their corrosion-resistant construction allows them to handle aggressive vapors common in chemistry and pharmaceutical work, while sealed designs reduce the risk of process contamination.

Common Applications

These pumps are a staple in filtration, degassing, rotary evaporation, and vacuum drying. They are frequently paired with rotary evaporators and vacuum concentrators, and they support pharmaceutical, food and beverage, and general laboratory workflows where dependable, contamination-free vacuum is essential.
