Hydraulic fracturing pumps to enhance flow of fracturing fluid into wellheads and related methods

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.

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.

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 including the crankshaft and at least one planetary gearbox arranged at an end of the hydraulic fracturing pump, such that rotating the crankshaft drives the crankshaft to cause movement of the at least one planetary gearbox, and
• the crankshaft connected to a plurality of plunger pairs including a first plunger pair, a second plunger pair, a third plunger pair, and a fourth plunger pair arranged consecutively relative to a longitudinal axis of the crankshaft, thereby to engage the plurality of plunger pairs in a non-consecutive sequence including reciprocating the first plunger pair, then the third plunger pair, then the second plunger pair, and then the fourth plunger pair;
• 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.
