Uncompromising chemical resistance

The VACUUBRAND stability core principle

The unique stability core design of high-stress components - such as the head cover and diaphragm clamping disc - ensure reliable performance over the long term. The stability core is created through a multi-step manufacturing process which creates a thick layer of fluoropolymer wetted material. Together with the perfluoroelastomer valves and seals, these materials provide outstanding chemical resistance and minimal surface adherence. This prevents the degradation of the pump from chemical corrosion.

Unsurpassed long-term performance

Service intervals of 5 years or more

The already long diaphragm life time of approximately 15.000 working hours is increased considerably by the intelligent VARIO control. VARIO pumps deliver precise vacuum by adjusting the motor speed. This technology minimizes wear on the pump, extending typical maintenance intervals to 5 years or more for many customers.


100 % quality control

Each vacuum pump goes through an extensive performance test at our facility, measuring specifications and equipment reliability with computer-controlled measuring and test machines and a fully automatic final test stand. That is how we guarantee that vacuum pumps from VACUUBRAND are not only designed to an exceptionally high-level engineering standard, but also offer extraordinary lifetime cost advantages because of their low service costs and above-average lifetimes.

Precisely optimized vacuum

VARIO - precise motor speed control

VARIO-pumps provide pinpoint vacuum control by adjusting the motor speed. This guarantees optimal process times and reproducible results. VARIO-pumps run on demand for maximum energy efficiency, increased service intervals, and whisper quiet operation.


VARIO - fully automatic evaporations at the touch of a button

No more “babysitting” – with automatic evaporation, boiling points are detected at the touch of a button and the pressure is continuously adapted throughout the evaporation. Even critical solvent mixtures are quickly and safely evaporated without bumping or foaming.

Minimal operating costs

Reduced power consumption and long service intervals

The intelligent VARIO motor speed control minimizes power consumption and wear on the pump.
In comparison to vacuum pumps with constant motor speed, power consumption is reduced by up to 90 % during laboratory operation.Typical maintenance intervals are extended to 5 years or more for many customers.


No oil or water required

Diaphragm pumps run oil-free and without water. They produce no waste water or waste oil.

Whisper quiet operation

Enjoy the silence

The patented new drive system of our chemistry diaphragm pumps guarantees extra quiet, ultra-low-vibration operation. Due to the VARIO control, the pump runs at a significantly reduced speed making the pump whisper quiet.
