It is usually not the pump itself that is noisy, it it the vibration of the surface it is attached to that creates most of the noise. I have had luck adding a piece of 1" pressed board between the water pump and the panel it is mounted to. Anything that will keep the vibration of the pump from being transferred wood surface it is attached to.
