Carbon fiber slurry pump sets a ten-year service record, reshaping the durability benchmark for titanium dioxide production equipment

2025-05-26


 

This slurry pump, which has been continuously operating for ten years on a large sulfuric acid titanium dioxide production line, is about to be displayed in an exhibition. It is from Chengdu YONGYI PUMPS Co., Ltd. This new carbon fiber composite slurry pump has achieved a record of ten years without replacement of the pump body/pump cover and more than 5 years of stable service for the impeller. This breaks the industry convention of monthly replacement of traditional metal pumps, marking a major breakthrough in the application of new carbon fiber composite pumps in corrosive industrial environments.

As the first slurry pump in this process section, this new carbon fiber composite pump has achieved a leapfrog improvement in service life from "monthly maintenance" to "annual durability". Under the harsh conditions of long-term contact with acidic titanium gypsum slurry, the new carbon fiber composite material exhibits excellent corrosion resistance and wear resistance, completely changing the past production pain points of frequent replacement of equipment parts. The successful application of this equipment not only significantly reduces the frequency of downtime maintenance, but also provides reliable assurance for the continuous and stable operation of the production line through material innovation.

"The decommissioning and display of this 'ten-year pump' is a microcosm of the deep integration of materials science and industrial manufacturing." The ten years of practice of the new carbon fiber composite pump, from early experiments to large-scale applications, proves that it has moved from "technology verification" to "mature standard configuration", providing a replicable solution for the durability upgrade of equipment in the chemical and metallurgical industries.

With the deepening application of new carbon fiber composite pumps in high-end equipment fields, industrial equipment with similar "long life and low maintenance" characteristics will accelerate the cost reduction, efficiency improvement, and green transformation of traditional manufacturing, becoming an important technological support for the high-quality development of process industries.
