A manually operable pump includes a fluid line operatively connected to a fluid source, and a manually operable actuator. A facilitator is used to facilitate flow of fluid from the fluid source through the fluid line. The facilitator is operably connected to the manually operable actuator. A piezoelectric system is operably connected to the manually operable actuator, and configured to capture energy from manual actuation of the manually operable actuator and regulate the speed of the facilitator.
