- innovative connections in new NT models ensure very low leakage rates, providing excellent vacuum flow rates and long-term performance stability, even after thousands of hours of operation.
- long diaphragm life: made of highly flexible FKM, reinforced with fabric.
- new patented drive assist system on NT pump models ensures extremely quiet operation.
- precise vacuum control by modifying the speed of the diaphragm pump to the needs of the application
- unparalleled diaphragm and valve life by reducing the total number of diaphragm strokes
- low energy consumption
- include patented TURBO - MODE with automatic speed control (VARIO® Pumps)
VACUUBRAND aluminum diaphragm pumps are ideal for many laboratory applications because they are oil-free and very quiet, and because they require so little maintenance. The diaphragms have a particularly long service life and hermetically seal the drive space from the pumping chamber to protect mechanical parts from corrosion. The pumps achieve their distinctly high performance due to the large volume of the pumping chamber relative to the minimal dead space. Highly flexible FKM double diaphragms with fabric reinforcement ensure extremely long diaphragm life. The pumps operate completely oil-free. In normal operation, they are completely free of abrasion. This makes VACUUBRAND diaphragm pumps the right choice for clean applications.
