XBD-L vertical single-stage single-suction fire pump set for conveying clean water without solid particles and liquid with physical and chemical properties similar to water. It is mainly used for pressurized water supply in fire protection system. In industrial and urban water supply and drainage, high-rise building pressurized water, long-distance water supply, heating, bathroom, boiler cooling and heating water circulation, pressurized air conditioning refrigeration system water supply and equipment supporting and other occasions.
The performance and technical conditions of the XBD-L fire pump unit produced by our company are in line with the requirements of the national newly issued GB6245-1998 "Fire pump performance requirements and test methods". The products have been tested by the National Fire Equipment Quality Supervision and Inspection Center. Qualified and obtained the Shanghai Fire Protection Product Certification.
The company's products are all designed and optimized by computer. The company has strong technical strength, rich production experience and perfect testing methods to ensure the stability and reliability of product quality.
1. Compact structure, small size and beautiful appearance. Its vertical structure determines the installation area is small, and its center of gravity coincides with the center of the pump foot, thus enhancing the running stability and service life of the pump.
2, smooth operation, low noise, high component concentricity.
3. Adopt advanced hydraulic model, high efficiency and excellent performance.
4. The shaft seal adopts high-quality mechanical seal, which has the characteristics of wear resistance, no leakage and long service life.
5. The pump inlet and outlet are on the same horizontal axis, and the caliber specifications are the same, which is convenient for pipeline connection and convenient for loading and unloading.
6. It is convenient to maintain. It is not necessary to dismantle the pipe. Just remove the pump cover nut and take out the motor and transmission components for maintenance.
