Descrição geral do projeto
Country: Indonesia
Indústria: Lithium Battery Materials / Spodumene Lithium Extraction
The customer is engaged in spodumene lithium extraction using the sulfuric acid leaching process. The production line includes crushing and grinding, roasting, sulfuric acid leaching, impurity removal, filtration, evaporation, concentration, and lithium carbonate precipitation.
During long-term operation, the plant continuously transfers high-temperature acidic slurry and high-solid-content mineral slurry. The original metal centrifugal pumps frequently experienced casing corrosion, impeller wear, mechanical seal leakage, and excessive vibration after only 3–5 months of service.
The most severe problems occurred in the acid leaching and filter press feeding sections, where the slurry contained both sulfuric acid and fine mineral particles. The combination of chemical corrosion and abrasive wear significantly reduced pump service life and increased maintenance downtime, affecting the stability of the entire lithium production process.
Challenges in Lithium Processing Slurry Transfer
As a critical lithium processing pump application, the acid leaching process presents several operational challenges:
- Strong sulfuric acid corrosion
- Abrasive wear caused by fine mineral particles
- High solid concentration slurry transfer
- Mechanical seal leakage risks
- Unstable slurry feeding performance
- Continuous operation under elevated temperatures
These issues often result in frequent maintenance, reduced filtration efficiency, and increased operating costs.
Pump Solution
To address these challenges, Bomba Changyu supplied a UHB corrosion-resistant slurry pump for the acid leaching and slurry transfer sections.
The pump is specifically designed for handling corrosive and abrasive slurries commonly found in lithium processing plants, mining operations, and chemical industries.

Why UHMWPE Was Selected
The wetted components of the pump are manufactured from UHMWPE (Ultra-High Molecular Weight Polyethylene), which combines excellent corrosion resistance and abrasion resistance in a single material.
Resistência à corrosão
UHMWPE offers outstanding resistance to sulfuric acid and various chemical solutions used during lithium extraction processes.
Resistência à abrasão
The material can effectively withstand continuous erosion caused by mineral particles and high-solid-content slurry.
Reduced Leakage Risk
The external mechanical seal design helps minimize leakage and improve operational safety.
Longer Service Life
Compared with conventional metal pumps, UHMWPE-lined slurry pumps can significantly reduce wear-related failures and extend maintenance intervals.
Resultados do projeto
After installation, the pump system achieved stable operation throughout the lithium processing plant.
The customer reported:
- Reduced pump casing corrosion
- Lower impeller wear rates
- Improved slurry feeding stability
- Fewer maintenance shutdowns
- Reduced spare parts consumption
- Extended continuous operating cycles
By combining corrosion resistance and abrasion resistance, the UHB slurry pump provided a reliable solution for sulfuric acid slurry transfer and helped improve overall production stability within the lithium extraction process.
