VARIO^® chemistry pumping unit PC 3012 NT VARIO select DUO

The VARIO® DUO pumping units are consisting of a combination of two individual VARIO® pumping units, connected in parallel on the suction side and driven synchronously by one vacuum controller VACUU·SELECT. The vacuum is controlled accurately. The speed of the two individual pumps is exactly adjusted to the vacuum needs. The controller allows both fully automatic distillations without any user pre-settings as well as specific and reproducible program sequences. The integration into existing control systems via digital and analog interfaces is also possible. The consequent design to highest chemical resistance provides the ideal prerequisite for universal use in chemistry and pharmacy - without any operating fluid such as water or oil.
The unique combination of high chemical resistance, very good ultimate vacuum and high pumping speed with low energy consumption and without any operating fluid makes the new VARIO® DUO pumping units the contemporary vacuum source for many applications in the range of kilo-lab, pilot and small productions. They are also used as network pumping units for larger VACUU·LAN® - installations or as an environmentally friendly alternative to existing central vacuum systems. The VARIO® control provides the required vacuum all the time and automatically adjusts the speed of the two pumps to the needs. This results in prolonged maintenance intervals in addition. The low noise level allows placement within the workspace.
Chemistry diaphragm pumps from VACUUBRAND for aggressive gases and vapors are available in the basic version, with two-point or VARIO® control.
Chemistry diaphragm pumps from VACUUBRAND for aggressive gases and vapors are available in the basic version, with two-point or VARIO® control. Their construction with fluoropolymers makes them very resistant to chemical vapors from inlet to exhaust.
