Claim 12:
13. A method of operating a hydraulic fracturing pump associated with a high-pressure fracturing operation, the method comprising:
rotating a crankshaft of a hydraulic fracturing pump, the hydraulic fracturing pump comprising a drive assembly with at least one planetary gearbox arranged at an end of the hydraulic fracturing pump, and the crankshaft connected to a plurality of plunger pairs arranged consecutively relative to a longitudinal axis of the crankshaft, thereby to engage the plurality of plunger pairs in a non-consecutive sequence along the longitudinal axis;
pumping a first fracturing fluid having a first fracturing fluid composition via a plurality of first plungers of the plurality of plunger pairs; and
pumping a second fracturing fluid having a second fracturing fluid composition via a plurality of second plungers of the plurality of plunger pairs, the first fracturing fluid composition being different than the second fracturing fluid composition.
