Claim 9:
10. 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 by driving opposite ends of the crankshaft from corresponding opposite ends of the hydraulic fracturing pump, 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 corresponding first plunger of each of the plurality of plunger pairs; and
while pumping the first fracturing fluid, pumping a second fracturing fluid having a second fracturing fluid composition via a corresponding second plunger of each of the plurality of plunger pairs, the first fracturing fluid composition being different than the second fracturing fluid composition.
