CYZ Self-Priming Centrifugal Oil Pump is used to transport petroleum products such as gasoline, kerosene, diesel, and aviation fuel. The medium temperature ranges from -20°C to +80°C, making it an excellent marine oil loading and unloading pump. It is also suitable for oil transportation in land-based oil depots, oil tankers, and other oil storage facilities. It can also be used to transport seawater, freshwater, and other liquids.     This pump belongs to the self-priming centrifugal pump category, featuring a simple structure, convenient operation and maintenance, stable operation, high displacement, high efficiency, easy adjustment, and a wide range of applications.     It adopts an axial liquid-return pump body structure, consisting of a suction chamber, liquid storage chamber, vortex chamber, liquid return hole, and gas-liquid separation chamber. The pump's bearings are single-row radial ball bearings. A cooling chamber is located at the bottom of the bearing body, and sealing rings are installed between the high and low-pressure areas inside the pump. The shaft end uses mechanical seals.
