Pump operators handle pumps and manifold systems that transfer liquids, gases, and powdered material at a variety of utility and manufacturing plants. As a pump operator, you monitor pressure and temperature gauges to ensure that there are no abnormalities with the transfer of the materials. Your responsibilities include keeping a careful record of all the data you observe and paying attention to any discrepancies that might indicate a safety or operational problem. Pump operators also tend to the vessels that contain the materials they are pumping. For a career as a pump operator, you need strong mechanical skills, the ability to read gauges, and be able to perform simple math and data analysis.
