Mechanical booster pump EH4200
The EH series is ideal for high-pressure differential applications, allowing the booster pump to be started at the same time as the backing pump, reducing total evacuation time and making operation easier. Mainly used in vacuum coating, freeze drying, vacuum leak, vacuum packaging, metallurgy and other industries.
Classification:
