Abstract: A system and method for injecting slurry includes a first elongated tank comprising a first end having a first volume and a second end having a second volume, said first volume separated from the second volume, a first pipe having a first end external to the first elongated tank receiving clear fluid and a second end coupled to the first volume and a plurality of slurry valves fluidically coupled to the first elongated tank. The plurality of slurry valves have a first state communicating high pressure slurry from the second volume to the slurry injection site and a second state communicating low pressure slurry into the second volume. A plurality of clear fluid valves are fluidically coupled to the first elongated tank and communicate high pressure clear fluid to the first volume in the first state and communicate low pressure clear fluid from the first volume in the second state.

Abstract: A fluid machine has a housing and a rotating portion that rotates relative to and is at least partially disposed within the housing. The housing is coupled to a seal assembly comprising a plurality of seal channels having a plurality of seal rings. Each of the plurality of seal channels comprises a respective one of the plurality of seal rings.

Abstract: A turbine and method of operating the same includes a housing having a volute and an outlet and an impeller rotatable coupled to the housing. The turbine includes a nozzle ring having a plurality of primary nozzles and a plurality of secondary nozzles. The plurality of primary nozzles and the plurality of secondary nozzles direct fluid toward the impeller. An auxiliary valve assembly selectively communicates fluid from the volute to the plurality of secondary nozzles. An actuator is coupled to the valve auxiliary assembly moving the auxiliary valve assembly from a first position communicating fluid from the volute into the secondary nozzles to a second position blocking flow of fluid to the secondary nozzles.
