Designed instruction of long shaft submerged pump
NFY/FYS Long Shaft Submerged Pump is a single-stage, single-suction vertical centrifugal pump. The design conforms to API610 VS4 Standard. The pump shaft utilizes a reliable connected shaft form, allowing the pump body to be submerged to depths of up to 7 meters. The submerged parts of the shaft are supported by sliding bearings, eliminating the need for shaft sealing. The upper liquid section incorporates angular contact ball bearings, with Grease Lubrication as the chosen lubrication method.
This pump features specially designed axial adjustment mechanisms that enable fine-tuning of the clearance between the impeller back-blade and the pump cover, ensuring balanced axial force. The unique balanced cavity structure helps relieve pressure, ensuring stable operation over time. It offers two flushing models—self-flushing and outside flushing—to lubricate and cool the sliding bearings, adaptable to different liquid temperatures and particle content. The sliding bearings are equipped with gland packing to prevent impurities from entering, reducing bearing wear and prolonging the pump’s working life.
Application areas of long shaft submerged pump
The NFY/FYS Long Shaft Submerged Pump is widely utilized across various industries for the efficient handling of a diverse range of liquids. It is particularly effective in the pumping of industrial wastewater, surface treatment processes, and the transportation of sulfuric acid, sulfur liquid, or other neutral or corrosive media. This pump is capable of transferring both clean liquids and those containing particles and fibrous content.
Its versatility makes it an essential component in fields such as biological medicine, petrochemical, mining, metallurgy, textile printing and dyeing, electricity, food processing, papermaking, electroplating, sewage treatment, and flue gas treatment. Additionally, it is increasingly being adopted in emerging sectors like new energy and new materials industries, where its robust design and reliable performance are highly valued.
