Project Requirement

      Recently, a marine engineering enterprise in Yantai, Shandong Province, in order to meet the critical water supply and drainage demands of its large-scale project construction, conducted rigorous market research and technical comparison, and ultimately selected the 600LC-39 vertical long-shaft lift pump  manufactured by Changsha Zoomlian Pump Industry Co., Ltd. as the core equipment. This procurement decision reflects the enterprise's comprehensive consideration of equipment reliability, efficiency and professional services.

Located on the coast of the Yellow Sea, marine engineering projects in Yantai are often confronted with complex operating conditions, especially challenges such as the strong corrosiveness of seawater medium, large water level fluctuations, and the need for long-term continuous operation. The 600LC-39 vertical long-shaft lift pump procured this time is an excellent product specially designed for such harsh environments. Adopting a vertical long-shaft structure, the pump can effectively adapt to the lifting of water from relatively deep sources. Its core flow-passing components are made of special corrosion-resistant and wear-resistant materials, ensuring long-term stable operation in the transportation of seawater and other complex media. With a standard head of 39 meters and a large-caliber design of 600 mm, it can meet the project's requirements for large-flow and medium-to-high-head transportation, guaranteeing the strong power of the water supply and drainage system during construction or production.

 

When talking about the selection process, the technical director of the enterprise stated that besides the pump's excellent technical parameters and adaptability, the profound R&D strength and rich engineering application cases accumulated by Changsha Zhonglian Pump Industry in the field of large-scale industrial pumps, especially in the vertical long-shaft pump product line, are the key factors to win trust. The professional selection support, sound after-sales service system and timely technical response capability provided by Changsha Zhonglian Pump Industry are crucial to ensuring the smooth progress of key projects.

 

This cooperation is not only a single equipment procurement, but also an in-depth docking between professional users in the marine engineering field and a leading domestic pump enterprise. The commissioning of the 600LC-39 vertical long-shaft lift pump will provide solid and reliable fluid transportation guarantee for the marine engineering operations of the Yantai enterprise, helping it improve construction efficiency and operational safety. It also demonstrates that domestic high-end industrial pumps are playing an increasingly important supporting role in major infrastructure and marine economic construction projects.

Customers say this
As a marine engineering enterprise engaged in large-scale projects in Yantai, we have extremely high requirements for the reliability and adaptability of water supply and drainage equipment due to the complex operating conditions such as strong corrosion of seawater, large water level fluctuations, and the need for long-term continuous operation in coastal construction.
After rigorous market research and technical comparison, we finally selected the 600LC-39 vertical long-shaft lift pump produced by Changsha Zhonglian Pump Industry. Since its commissioning, the pump has fully demonstrated outstanding performance advantages, which have exceeded our expectations.
Firstly, its excellent corrosion resistance and wear resistance are particularly prominent. The core flow-passing components made of special materials can stably operate in seawater medium for a long time without any failure caused by corrosion, which greatly reduces our maintenance costs and downtime. Secondly, the pump's performance parameters are highly consistent with the actual needs of the project. With a standard lift of 39 meters and a large-caliber design of 600mm, it achieves efficient large-flow transportation, ensuring the stable operation of the entire water supply and drainage system during the construction process. In addition, the vertical long-shaft structure enables the pump to adapt well to the deep water source environment of our project, and the long-term continuous operation performance is stable, without any problems such as insufficient power or sudden shutdown.
The outstanding performance of the 600LC-39 vertical long-shaft lift pump has provided a solid guarantee for the smooth progress of our marine engineering projects. We are very satisfied with this product and highly recommend it to other enterprises facing similar harsh working conditions. We also look forward to continuing to cooperate with Changsha Zhonglian Pump Industry in future projects.
