An injection system includes an injector pump delivering a mixture of polymer and water from a mixing tank. Optionally, a surge tank is provided to reduce pressure hammer effects. The mixture is delivered by the injector pump to a manifold device that includes a commutator valve receiving the mixture through an inlet and discharging the mixture through two or more outlet ports. An actuator controls the flow of the mixture through the commutator valve to create pulses in the mixture. Optionally, the actuator is controlled by a controller. The mixture is delivered from the outlet ports to nozzle arrays.
