It is very important to maintain the stability of pump pressure in water mist system for higher fire suppression efficiency. In recent years, the optimization of design of the multi-plunger pump to reduce the pulsation of output pressure is an urgent problem to be solved. In the present study, the flow pulsation and frequency characteristics of multi-plunger canted disc link pump were simulated based on the kinematical equations. The kinetic characteristics of this type of pump were expounded through the calculation results. The effects of plunger number, canted disc dip angle, rotate speed, diameter and location of ball socket reference circle on the flow pulsation and frequency characteristic of the pump were also studied.
