1. A pumping system, comprising:
a pump 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; and
a prime mover mechanically coupled to a crankshaft configured to reciprocate the plungers;
a torque monitoring system configured to monitor torque of the pump;
one or more additional pumps; and
a controller configured to increase pumping rate of the one or more additional pumps, in response to detecting the torque changing from positive to negative or from negative to positive during cyclic rotation of the crankshaft.
