The comprehensive FLOWSERVE SIHI® range of liquid ring vacuum pumps are available in single and two stage designs, with suction capacity up to 12 000 m³/h (7063 cfm) and pressures in the range 33 (25) to 1013 mbar (760 Torr) without further boosting equipment. Additionally, the liquid-ring principle is also used as a compressor in which to generate positive pressures up to circa. 13 barg (188 psig).

Benefits of Vacuum Pumps:

  • Complete packages for vacuum, gas and liquid applications
  • Extremely robust
  • Cool operation
  • Superior liquid, vapour and solids handling
  • High volumetric flow-rate
  • Simple maintenance available in a wide rage of materials

Central Vacuum and House-Keeping Systems

Spencer central vacuum systems are custom designed for each facility with a centrally located vacuum producer, dirt separator or material collector, connected to a metallic vacuum tubing network. They extend “vacuum power” throughout operations of any size, providing intense cleaning power, and much more including: fume removal, liquid spill pickup, hazardous and recyclable goods collection, bulk material conveying, vacuum hold-down or pickup, etc.


  • Modular central vacuum systems
  • Mobile or stationary integrated vacuum units
  • Dust collectors and separators
  • Bulk material handling
  • Liquids handling
