In single-flow arrangements suction speeds of 250 to 16 000 m³/h are possible. Higher suction speeds can be achieved by adding pumps system in parallel. The achievable working pressure depends on the number of pump stages and of pump systems in parallel!
RUTA Pump Systems
Usually RUTA vacuum systems are combinations of Roots vacuum pumps of the type WA, WS and RA or WAU and WSU with integrated bypass line with oil-sealed backing pumps for conventional generation of the vacuum. Single stage arrangements are capable of delivering pumping speeds of 250 to 16 000 m3/h (147 to 9424 cfm). Higher pumping speeds can be attained by paralleling several pumps. The attainable operating pressures depend on the number of pumping stages.more
