How do you analyze and dampen pulsation in reciprocating pump systems?

Pulsation sources: discrete flow pulses from plunger action create pressure waves. Analysis: API 674/618 guidelines, acoustic simulation of piping system to find resonant frequencies, avoid coincidence with pump pulsation frequencies. Dampening methods: pulsation dampeners (gas-charged or all-liquid bladder type) sized for volume change, acoustic filters (volume-choke-volume), orifice plates (adds damping but permanent loss), and proper pipe sizing (limit velocity). Suction stabilizers prevent acceleration head problems. Complex systems require acoustic analysis software (Beta, PulsaTrol).
