Clean operation (oil free), low cost of ownership, highest reliability – these are just a few benefits that customers can appreciate when they use a diaphragm pump for laboratory or industrial applications. With a broad range of diaphragm pumps – ultimate vacuum from 75 to 1 mbar and peak flow rates up to 138 l/min – Welch offers specific pump families and models for a variety of uses. The rugged low maintenance pumps have PTFE heads, perfluoroelastomer valves, and fluorinated plastic wetted surfaces, making DryFast a durable choice for solvent, acidic, and basic vapors.
Model 2047 provides effective filtration of strong chemical vapors, such as chlorinated solvents, strong acid/base solutions and ketones. Includes built-in vacuum regulation using a bleed valve mounted on the front panel.
