  • Seal support system pressure tracking value
    Patent number: 9098094
    Abstract: A pressure regulation tracking valve for maintaining the pressure of a gas relative to that of a process fluid includes a device, responsive to change in the pressure of the process fluid, for changing the pressure of the gas by substantially the same amount. The valve further includes a device for accommodating a pressure transfer medium for transferring the pressure of the process fluid to the gas pressure changing device. As a result, contact between the process fluid and the gas pressure changing device is avoided.
    Type: Grant

  • Mechanical seal
    Patent number: 5927722
    Abstract: A cartridge seal having a sleeve for fitting over a pump shaft and, at one end region of the sleeve, a stationary seal whose floating component is biased towards its static component. The cartridge further includes a member longitudinally spaced from the seal, which member and the stationary seal are moveable longitudinally relative to one another. The floating component is biased away from said member and towards the static component, means being provided to limit separation of said member and the stationary seal. The invention therefore provides a complete mechanical seal in one cartridge.
