WebWith more than 5,000 pumps and 15,000 valves installed in over 200 nuclear reactors worldwide, it’s obvious that Flowserve is an industry leader in the nuclear space. In fact, … WebOnly since 1954 has this principle been employed in vacuum engineering. Roots pumps are used in pump combinations together with backing pumps (rotary vane or dry pumps) and extend their operating range well into the medium vacuum range. With two stage Roots pumps this extends into the high vacuum range. The operating principle of Roots pumps ...
