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.
