自由容器

The D-type horizontal multistage pump is characterized by high efficiency, a wide performance range, safe and stable operation, low noise, long service life, and convenient installation and maintenance. It is suitable for conveying clean water or other liquids with physical and chemical properties similar to those of water. By changing the materials of flow-through components, sealing types, and adding cooling systems, it can also be used to transport hot water, oils, corrosive media, or media containing abrasive particles.

Application

The D-type horizontal multistage pump is primarily used for industrial and municipal water supply and drainage, pressurized water supply for high-rise buildings, garden sprinkler systems, fire-fighting pressurization, long-distance water transmission, heating and cooling water circulation pressurization for bathrooms and other facilities, as well as equipment matching. It is particularly suitable for feed water of small boilers.
