    A power plant in Xinjiang has purchased a self-balancing boiler feed pump, model DG85-80*9P, from Zhonglian Pump Industry.

    A power plant in Xinjiang has purchased a self-balancing boiler feed pump, model DG85-80*9P, from Zhonglian Pump Industry.

    Recently, Zhonglian Pump Industry reached a cooperation agreement with a power plant in Xinjiang to supply it with DG85-80*9P self-balancing boiler feedwater pumps for its boiler feedwater system. The equipment has now completed production, transportation, and on-site installation and commissioning, and has officially been put into stable operation. The boiler upgrade project at this power plant requires the pumps to be suitable for high-temperature and high-pressure operating conditions. The core requirement is continuous and stable delivery of deaerated water, with a medium temperature not exceeding 105℃, an inlet pressure no greater than 0.6 MPa, and the ability to meet the specified performance parameters of a rated head of 720 meters and a flow rate of 85 m³/h. Given that the lowest winter temperature in Xinjiang can drop as low as -20℃, the equipment must also demonstrate reliable starting performance under low-temperature conditions and comply with the GB/T12145-2016 standards for steam quality in thermal power generating units.

    D/F/Y/MSK Series Horizontal Split-Case Multistage Pumps

    D/F/Y/MSK Series Horizontal Split-Case Multistage Pumps

    The DSK, DFSK, DYSK, and MDSK series of horizontal, mid-open multistage pumps represent a new generation of large-scale, horizontally configured, mid-open multistage centrifugal pumps independently developed by Changsha Zhonglian Pump Industry. This product line features a dual-inlet design with symmetrically arranged impeller and rotor components; after the fluid flows through the final-stage volute casing and pressure chamber on both sides, it exits, forming a parallel-flow configuration. The pump boasts numerous outstanding characteristics, including high flow rate, high head, compact and aesthetically pleasing design, high efficiency and energy savings, a broad high-efficiency operating range, excellent cavitation resistance, smooth operation, convenient maintenance, and reliable performance. As a national high-tech product, it fills a critical gap in China’s market for high-parameter multistage centrifugal pumps with large flow rates and high heads. These pumps are widely used in industrial cooling-water circulation, secondary pressurization pumping stations for high-altitude water intake, agricultural irrigation, river-water intake, flood drainage, municipal engineering, and other applications.
