Single-Stage Single-Suction Pump: The XBD-W type single-suction single-stage fire pump consists of a motor and a pump, which are coaxial. The pump structure includes the pump body, impeller, pump cover, mechanical seal, etc. The pump inlet and outlet are on the same horizontal axis and have the same diameter, making installation and removal extremely convenient and requiring little space. The pump is equipped with a mounting base for easy installation and increased operational stability. The pump seal uses a mechanical seal, which is reliable and leak-free. The axial force of the pump is balanced by a balance ring on the impeller. The pump's inlet and outlet flanges are designed for a pressure of 1.6MPa, facilitating pipeline matching.
Single-Stage Multi-Suction Pump: The XBD-W type single-suction multi-stage segmented fire pump consists of a motor and a pump. The motor is a Y-type three-phase asynchronous motor. The fire pump and motor are connected by a coupling, forming a rigid connection that requires no calibration during use. The fire pump consists of a stator and a rotor. The stator consists of the inlet section, intermediate section, guide vanes, outlet section, stuffing box, etc. To prevent stator wear, the stator is equipped with sealing rings, balance sleeves, etc., which can be replaced with spare parts after wear. The rotor consists of a shaft, intermediate impeller, balance drum, etc. The lower end of the rotor has a water-lubricated bearing, and the upper part has an angular contact ball bearing. Most of the axial force of the pump is borne by the balance drum, and the remaining small portion of the residual axial downward force is borne by the angular contact ball bearing. The paper gaskets at the joint surfaces of the inlet section, intermediate section, and outlet section are tightened to achieve a seal, which can be selected by the user according to their needs.
