DG series centrifugal pumps, also known as multi-stage boiler feedwater pumps, handle and transport corrosive liquids or liquids with physical and chemical properties similar to those of clean water in various sectors, including chemical processing, petroleum, heating, power generation, industrial cooling water circulation, and long-distance water supply. By selecting appropriate materials for the flow-passing components and sealing configurations, these pumps can also be adapted to transport hot water, oils, and corrosive liquids, thereby meeting the pumping needs of a wider range of industries. For enhanced energy efficiency during operation, the pumps feature advanced hydraulic optimization and are equipped with high-efficiency motors, making them more energy-efficient than traditional equipment under equivalent operating conditions.
Product Details:
DG series multistage pumps employ a horizontal, single-suction, multistage segmented design and primarily consist of a stator, rotor, bearings, shaft seal, drive mechanism, inlet and outlet ports, and a coupling. When liquid is drawn into the center of the impeller, centrifugal force propels it outward at high speed, thereby increasing its kinetic energy. While decelerating, the liquid converts most of its kinetic energy into pressure energy, causing the pressure to rise, following this sequence of acceleration, deceleration, and pressurization, the liquid is ultimately discharged from the discharge section.
Application:
DG boiler feed water pumps are intended for conveying clean water or non-corrosive liquids with physical and chemical properties similar to those of clean water. As such, they are suitable for applications such as garden and agricultural irrigation, firefighting, pressurized drainage, boiler feedwater systems, long-distance water supply, heating systems, power systems, and industrial and municipal drainage.
Feature:
1. Its simple structure, rational design, and minimal number of components make installation and maintenance quick and easy, thereby reducing downtime caused by disassembly.
2. The equipment maintains stable operation even during high-speed operation, with low noise and low vibration, effectively improving the production environment and ensuring long-term operational stability.
3. The materials for the flow-through components and impeller can be selected based on operating conditions and the conveyed medium to ensure long-term, stable conveyance of the medium even under high-temperature and high-pressure conditions.
