Diaphragm pumps

Oil-free operation, easy to clean, whisper-quiet and requiring little service, giving high performance with a long diaphragm lifetime and little to no spare part costs.

Nearly all VACUUBRAND diaphragm pumps and measuring instruments have been approved for ATEX equipment category 3 in the vapor path

Diaphragm pumps

Besides contributing to the long service intervals the lack of abrasion also eliminates most of the particulate impurities frequently generated inside of scroll or piston pumps. This makes VACUUBRAND diaphragm pumps the right choice for clean applications.

  • Innovative connections in the new NT models ensure very low leak rates for excellent flow rates under vacuum and long-term performance stability, even after thousands of hours of service.

  • Long diaphragm and valve lifetimes: Made of highly flexible FKM, with fabric-reinforced double diaphragms for improved long term stability

  • New patented drive support system in NT pump models provide for uniquely quiet, low-vibration operation

  • No abrasion, making it dust- and contamination-free


Diaphragm pumps

Diaphragms have especially long lives and hermetically seal the drive space from the pumping chamber to protect mechanical parts from corrosion. The pumps achieve their distinctively high performance from high pumping chamber volume relative to the minimal dead space.
