A pumping system, comprising: a pump fluid end comprising a plurality of pump chambers, each pump chamber comprising a bore having a reciprocatable plunger disposed therein, a suction valve, and a discharge valve; a prime mover mechanically coupled to the fluid end [by a drivetrain] and configured to reciprocate the plungers; and a controller communicatively coupled to the prime mover, the fluid end, or both and configured to alert a user re a pump malfunction, initiate corrective action of the pump malfunction, or both in response to: (a) an indication of torque reversal during operation of the pumping system, (b) an indication of negative flow rate from the pump during operation of the pumping system, (c) an indication of leakage of (i) a single discharge valve in a 3-plunger pump or (ii) discharge valves associated with two plungers in adjacent firing order, or (d) any combination of (a)-(c).

Minimizing drivetrain damage from bad discharge valves on positive displacement pumps

The disclosure provides for a wellbore servicing system that comprises an engine operable to provide power to one or more pumps. The one or more pumps are operable to direct a fluid into a wellbore, wherein the engine is coupled to the one or more pumps via a transmission. The system further comprises an engine control module (ECM) coupled to the engine. The system further comprises a controller coupled to the one or more pumps and operable to determine the volumetric efficiency of each of the one or more pumps. The system further comprises an information handling system, wherein the ECM and the controller are communicatively coupled to the information handling system, wherein the information handling system is operable to determine a divergence when a load is placed on the engine and a pumping plan for the system.
