What is DG type sub-high pressure boiler feed pump

DG type sub-high pressure boiler feed pump is mainly used for sub-high pressure boiler feed water in thermal power plants, enterprise-owned power plants and cogeneration projects, or in other occasions for conveying sub-high pressure, high temperature clean water.

The hydraulic components of DG type sub-high pressure boiler feed pump are optimized and designed by CFD flow field analysis technology, with excellent performance. The impeller and guide vane are precision cast, with smooth flow channel, high dimensional accuracy and high efficiency. The rotor is dynamically balanced, and the accuracy level is higher than the industry level. The main key components are manufactured by machining center, with high precision and long life. The pump adopts central support structure as a whole, with sliding pin system, which can effectively compensate for thermal deformation. Some series are basically configured with diaphragm coupling, with stable transmission and good compensation. The whole series adopts cooling water integrated pipeline for water supply. If you choose to use mechanical seal self-flushing structure, you don't need to provide mechanical seal flushing water, which is convenient for users to install and use. There are two sealing forms for users to choose: mechanical seal and packing seal. From the suction section, the pump rotates clockwise.
