A high-efficiency noise-reduction hydraulic ram pump comprises a pump body, wherein the pump body is of a long cylinder structure, one end is a water inlet and is connected with a power water pipe, the other end is connected with a drain valve through a 90-degree elbow, the middle of the pump body is vertically connected with a water inlet pipe, and a water lifting valve is arranged on the water inlet pipe and is provided with an air chamber. The water inlet pipe is communicated with the air chamber through the water lifting valve, and a water outlet pipe is arranged on the air chamber and is communicated with the air chamber. The high-efficiency noise-reduction hydraulic ram pump is high in working efficiency, can improve the working efficiency to 85% or above, is low in noise and can control noise to 60 decibels or below.
