久經考驗的技術，行之有效的設計 — 選擇最佳解決方案
The Dolphin LG 1910 / 2680 A belongs to the Busch product family of proven Dolphin liquid ring vacuum pumps. You will find more information on advantages, technology, accessories and spare parts, applications as well as a complete product overview on our Dolphin LG series type page
Dolphin LG is a series of single-stage liquid ring vacuum pumps. An eccentrically mounted impeller rotates in a housing partially filled with operating fluid. The impeller blades dip into the fluid, and the centrifugal force exerted by their rotation forms a so-called liquid ring within the housing.
The pumped medium is transported in the spaces between the blades and the liquid ring. The eccentric rotation of the impeller alters the volume of these spaces, causing gas to be drawn in, compressed and expelled.
Dry air at 20 °C. Tolerance: - 5%, in accordance with HEI and Pneurop 6612
