Boosters and Gas Compressors
Description N/A Hurricane Series Compressors are used for Air or Nitrogen compression. Each compressor is an air-cooled, single acting, four stage, reciprocating piston compressor with the combination of oil pressure fed crankshaft bearings, and cylinder oil splash with regulated injection for the final high-pressure piston plunger design. Performance with inert gases, such as Nitrogen. N/A The industrial market has very specific demands. The new WP6000 meets those demands with turn-key water-cooled compressor packages that provide air or gas for your project. With up to six-cylinders, the WP6000 booster has a flexible design that can be customized to meet your exact specifications. Based upon Sauer's vast experience with robust Warship compressors for the World's Navies, the water-cooled WP6000 can be readily adapted using any combination of cylinders, or compression stages, to meet the precise requirement for flow and pressure.

Features
  • Proven concentric valves from Sauer's existing MP and HP product range in all stages.
  • Identical piston diameter in LP stages and HP crosshead guides for maximum flexibility. Cylinder, cylinder heads and coolers can be dismantled separately to ease maintenance and repair.
  • Pressure tight crankcase up to 290 psi.
  • Integrated flexible coupling and direct-drive for high reliability and low maintenance.
  • Pressure oil lubrication and 3-layer slide bearing for high sturdiness.
  • Low maintenance with the piston pin guided in a slide bearing.
  • Individual coolers for each cylinder/stage provide optimal cooling for all parts in the compression process.
  • Liners and wearing parts from Sauer established product range for cost and highest reliability.
 		N/A Mistral ('LB') Series inert gas boosters are dedicated nitrogen gas boosters that can accept suction pressures from 58-116 PSI to deliver gas to a maximum of 580 PSI. This single stage gas booster N/A Passat ('G') Series Compressor/Boosters have been engineered with a gastight crankcase ('special' double crankshaft seals and jointing) to prevent gas leakage, and are oil-lubricated, single acting reciprocating compressors with air-cooling. The 'G' series compressor/boosters are similar in performance to the 'H' series but are designed for noble gases such as Helium and Argon, and hazardous gases such as Carbon Monoxide and Natural Gas. Oil pressure fed to the crankshaft bearings and oil splash for compression, combined with Sauer regulated oil injection system for the final piston plunger design, ensures high reliability. The ability to handle elevated suction pressure for both noble or hazardous gases, gives enhanced performance to final pressures between 290 - 580 PSI reliably in three stages and from 1450 - 5075 PSI in four stages within the gas flow rate range of 5.9 - 236 SCFM. Models Available in ATEX Version: WP156L, WP276L, WP316L N/A Tornado Series Compressors are used for Air and Nitrogen compression. Each compressor is an air-cooled, single acting, three or four stage, reciprocating piston compressor with the combination of oil pressure fed crankshaft bearings, and cylinder oil splash with regulated injection for the final high-pressure piston plunger design. Performance with inert gases, such as Nitrogen.
