  • Pump life prediction system
    Patent number: 10982612
    Abstract: A pump life prediction system and methods for predicting pump life of a pump are disclosed. A method may include monitoring pump operating conditions. A value indicative of cavitation damage is determined based on the pump operating conditions. A pump life remaining is determined based on the value. The method may also include outputting an indication of the pump life remaining.

  • Liquid pump with cavitation mitigation
    Patent number: 10557446
    Abstract: A liquid pump applicable in a fuel system such as a common rail fuel system includes a valve assembly having a valve stack with axially aligned components, dead volume, and vapor-distributing flow channels, for cavitation mitigation. An inlet valve meters a flow of liquid into the pump for pressurization by a plurality of reciprocating plungers operated by way of a rotating camshaft.
