Project Introduction
A certain energy company in Tibet has purchased DF155-67X7P self-balancing multistage pumps.
The hydropower station owned by a certain energy company in Tibet is located in the central Tibetan region at an altitude of 3,600 meters. The natural environment there is harsh and features typical characteristics such as extreme cold, oxygen deficiency, and low atmospheric pressure. As electricity demand in the region continues to grow, the existing circulating water supply system’s pump units have gradually become unable to meet the requirements, exposing several serious issues: insufficient head, significant fluctuations in water supply pressure, and difficulties in motor cooling, which lead to power degradation and frequent malfunctions. These problems severely impact the stable power generation as well as the safe and economical operation of the power station.

Customer’s core needs:
1. Performance Matching: The pump unit must meet a head requirement of ≥460 meters and an appropriate flow rate of 155 m³/h to ensure stable pressure for tunnel cooling and auxiliary water supply to the equipment units.
2. Environmental Adaptability: The equipment must be capable of long-term, reliable operation under low-temperature conditions as low as -30℃ and at high altitudes up to 3,600 meters. The motor must feature excellent insulation performance and efficient heat dissipation to mitigate the risks of power degradation and insulation aging.
3. Durability and Maintenance: Given the remote location of the power station, the pump body must exhibit exceptional wear resistance and corrosion resistance, capable of handling water containing trace amounts of sediment. At the same time, it should be easy to maintain and have a low failure rate.
Changsha Zhonglian Pump Industry, through its Tibet office, has engaged in in-depth communication and tailored recommendations for its customers. DF155-67X7P Self-Balancing Multistage Pump This pump model is specially designed for harsh operating conditions and features a self-balancing hydraulic design, ensuring high operational efficiency and stability even under high-head requirements. The motor section has undergone special optimization, including the use of motors specifically designed for high-altitude environments and enhanced insulation and cooling systems, effectively addressing the heat dissipation and power challenges posed by high altitudes. The flow-path components are made from high-hardness, wear-resistant materials, significantly improving the overall durability of the pump unit and its adaptability to complex water qualities.
Since DF155-67X7P pump Since being put into operation, the unit has been in stable service for half a year. Its outstanding performance has completely resolved the long-standing water supply challenges faced by this hydropower station:
• The water supply pressure is stable and reliable, fully meeting the cooling requirements of the generator set.
• The equipment operates smoothly, with no downtime failures caused by the effects of the high-altitude environment.
• Maintenance costs have been significantly reduced, and its high reliability and low-maintenance characteristics have been highly acclaimed by customers.
The success of this project has not only earned the customer’s commitment to giving priority to Changsha Zhonglian pump products in the future, but also provided valuable practical examples and reliable technical options for selecting pump equipment in hydropower and new-energy projects located in high-altitude and cold-climate regions.
