Vacuum pumps for waste disposal vehicles SL 2100, SL 2700, SL 3100 - 1

Vacuum pumps for waste disposal vehicles SL 2100, SL 2700, SL 3100 Pressure range: 150 mbar to 1.5 bar (overpressure) Suction volume flow: 1010 to 3080 m³/h CONSTRUCTION Sterling SIHI liquid ring vacuum pumps are displacement pumps of uncomplicated and robust construction with the following particular features: • handling of all gases and vapours • robust operating behaviour • insensitive to entrained liquids • low noise level, nearly free from vibration • direct drive or belt drive • very little wear because of regular dirt drain (out of the pump) and application of steel as construction material • symmetrical design therefore optionally clockwise or anticlock-wise operation by easy shifting of the shaft • no lubricant in the working chamber • compact design, small size • option for internal evaporation cooling, thereby omission of additional external cooling for the operating liquid • wide effective speed range from 800 to 1600 rpm • weight-saving construction • leak proof shaft seal, optionally: Special seal with radial shaft seal ring and gland packing ring or mechanical seal with bellows.
