These diaphragm pumps combine modern control electronics and software with powerful mechanical components. They control the vacuum with pinpoint precision by adjusting the speed of the pump; they enable automatic vapour pressure detection and the automatic adaptation of the vacuum level to the course of the process. The fast, adaptive control provides the appropriate flow rate for every task, regardless of the size of the equipment or the volume of gas. All VARIO diaphragm pumps comprise the pump, the vacuum controller with display and the vacuum sensor.

• Optimum control of a specified vacuum
• Faster evacuation times (increased speed)
• Exceptionally low final pressure with patented 'TURBO-Mode'
• Rapid process times due to external or internal speed presets
• Separate vacuum controller for measuring vacuum at the appropriate point
