The DIVAC line of vacuum pumps is the logical continuation of diaphragm pump technology, which was developed especially for chemical applications ​and Clean-duty applications. Leybold's diaphragm pumps are essential for clean, oil-free vacuum typically in laboratory environment.

The DIVAC L series is highly resistant to chemicals and solvents, making it ideal for demanding lab work. Built with PTFE, FFPM, and PVDF components, it ensures durability and compatibility with aggressive media.

The DIVAC T and HV3 series serve as efficient, dry-running backing pumps for turbomolecular systems, delivering low ultimate pressures down to 0.5 mbar. The 1.4 HV3C variant adds advanced chemical resistance and adjustable speed control for tailored performance. The 3.8 HV3 and 4.8 VT models provide higher pumping speeds and are ideal for applications requiring faster evacuation in the rough and medium vacuum ranges.

With quiet operation, compact design, and minimal maintenance, Leybold diaphragm pumps offer reliable performance backed by decades of vacuum technology expertise. They are perfect for applications where a clean, contamination-free vacuum is critical, such as backing pump for wide range turbomolecular pumps, for analytical instruments, chemical, biological or pharmaceutical laboratories.
