Pump Description

XBD-DLL type verticalmulti-stage fire pumpGroup is a new product developed in accordance with relevant fire safety standards and regulations based on the needs of fire protection in China. The XBD-DLL fire pump is characterized by its high-speed structure, which reduces the number of stages compared to medium speed fire pump sets, resulting in a significant reduction in unit height and weight; The shaft seal adopts mechanical sealing, the water pump has no leakage, and the pump room is dry and clean; The unique bearing box structure allows for easy installation and maintenance by simply removing the motor and replacing the bearings and mechanical seals. The head interval is small, and one level can be set every 10 meters. Easy to design and select.

Pump structure description

The pump unit is a vertical multi-stage segmented structure, with bolts used to clamp and connect the inlet and outlet sections together. Each stage of the pump is equipped with an impeller. The axial force of a guide vane and pump is solved by hydraulic balance method, and the residual axial force is borne by a ball bearing and lubricated with grease.

The suction port of the pump is located below, and the discharge port is located above. The relative position between the two is assembled at a 180 ° angle when leaving the factory. Except for the first stage pump, users can adjust the direction of the outlet section at 90 °, 180 °, and 270 ° according to their needs. Remove the tightening bolt to adjust the installation position of the exhaust outlet. The pump set can work with 2-3 water outlets simultaneously.
