An impulse pump is provided with a low power motor to store rotational kinetic energy in a flywheel. The stored kinetic energy is released using a planetary gear transmission that links the flywheel to a pusher shaft. The kinetic energy is released when the planetary gear carrier is decelerated using a caliper brake. The planetary gear carrier deceleration forces rotational acceleration of the pusher shaft and deceleration of the flywheel. Through a cam roller contact point between the pusher shaft and the cam raceway on the plunger the rotational motion of the pusher shaft is converted to linear and translational motion of the plunger. The translational motion of the plunger allows impulse jet energy to be rapidly released from a nozzle of the pump.
