The vibration of a pump assembly, comprising a prime mover, a multiplex fluid pump connected to a drive line, and a transmission connected to transfer torque from the prime mover to the drive line to reciprocate a plurality of plungers, and a source of harmonic excitation, is inhibited by coupling a counteracting resonant system to the pump assembly, wherein the counteracting resonant system has an oscillatory frequency matching the harmonic excitation source. Also disclosed are a pump assembly comprising the prime mover, the multiplex fluid pump, the drive line, the transmission, and the counteracting resonant system; and a pumping method comprising connecting the transmission to transfer torque from the prime mover to rotate the drive line, connecting the drive line to the multiplex fluid pump, and coupling and tuning the counteracting resonant system to the induced harmonic excitation.
