The invention discloses a circular diaphragm booster pump, which relates to the technical field of booster pumps. The booster pump cylinder is provided with multiple cavities, and the booster pump is divided into a drive end and a hydraulic end; a crankshaft connecting rod crosshead assembly is installed at the drive end, and a circular diaphragm assembly is installed at the hydraulic end. The circular diaphragm assembly includes an inner cylinder, a circular diaphragm, and an outer cylinder with a cylinder cover, with a one-way valve at the cavity for inlet and outlet. One end of the inner cylinder is connected to a diaphragm cylinder sealing filler assembly, which includes a hydraulic plunger cylinder sleeve and hydraulic plunger, and the hydraulic plunger is connected to the drive plunger. The hydraulic plunger is connected to a compensation one-way valve, and a diaphragm adaptive relief valve is assembled at the cavity, with one end of the diaphragm adaptive relief valve connected to the compensation one-way valve. This circular diaphragm booster pump creatively uses a small diameter circular diaphragm to replace a large diameter circular diaphragm, solving the traditional diaphragm booster pump's problems of large circular diaphragm and large booster cylinder diameter structure layout difficulties and the unfavourable issue of axial fastening due to large load on the limiting plate. The integrated structure of the hydraulic plunger and compensation system addresses the problem of fluid compensation power waste in existing diaphragm booster pumps.
