  • Patent number: 7794211
    Abstract: A self priming pump system that includes a motor coupled to a centrifugal pump for driving the centrifugal pump. A separator having a reservoir is provided for storing a limited amount of pumped fluid in advance of the centrifugal pump. A vacuum source provides a vacuum suction to the reservoir to draw pumped fluid into the reservoir to prime the pump. To increase the reliability of the vacuum pump system, a deflector and/or extension may be provided in the reservoir to help prevent pumped fluid from entering the vacuum pump input. Also, the configuration of a tank used to store liquid for the vacuum pump system may be configured to separate and collect sediments near a drain port, which then can be easily drained. For positive head pressures, one or more valves may be used to prevent pumped fluid from escaping the reservoir, if desired.

  • Patent number: 6652241
    Abstract: The invention relates to a method and compressor module for compressing a gas stream of entry temperature t1 with the aid of hydraulically driven piston compressors in two compression stages of an entry pressure p1 from an intermediate pressure p2 after the first compression stage and from intermediate pressure p2 to an exit pressure p3 after the second compression stage, whereby the gas stream compressed to the intermediate pressure p2 is cooled back down to the entry temperature t1 before entering the second compression stage, and identical pressure ratios p3/p2=p2/p1 are used in the compression stage. According to the invention, the pressure ratios are adjusted by correspondingly adapting a hydraulic fluid stream for driving the first compression stage and a hydraulic fluid stream for driving the second compression stage with regard to the flow rate thereof with the aid of two adjustable hydraulic fluid pumps.
