Intended for structured formulation workflows, the Diaphragm Vacuum Pump MD 4 Series MD 4C NT is a three-stage, high-power device designed for continuous, oil-free evacuation and conveying of gases and vapors. This pump offers an extremely high delivery rate approaching the end vacuum, making it a suitable alternative to rotary pumps in various lab applications. Its exceptional chemical resistance and high vapor and condensate resistance, coupled with an integrated gas ballast valve, make it ideal for handling aggressive and corrosive substances, such as those encountered in rotary evaporators, drying ovens, gel dryers, and numerous other laboratory vacuum applications without solvent recovery. With a weight of 14.3 kg, this pump operates on a 230 V, 50/60 Hz mains connection and delivers a suction capacity of
