Description

The ChemStar belt vacuum pump manufactured by WELCH is designed to withstand harsh chemical pollution. The large oil reservoir with PTFE surface can dilute the pollutants, and the low rpm can reduce friction, thereby reducing the working temperature and chemical effects. The ChemStar system comes with gold oil, which is a synthetic lubricant for minimizing the influence of chemical contaminants.
