  Everyone knows that the fire fighting jockey pump is composed of a pressure water tank, a water pump, a control cabinet, a control instrument, a pipe fitting, etc. The fire pump is composed of a motor and a pump. The pump structure includes components such as a pump body, an impeller, a pump cover, a mechanical seal, and the like, and the pump and the motor are coaxial. The axial force of the pump is balanced by the balance ring of the impeller. The pump inlet and outlet are on the same horizontal axis and the caliber specifications are the same. The pump is equipped with a mounting base for easy installation and increased pump stability.
