The primary function of the expeller is to achieve sealing and prevent slurry leakage through its unique design. It plays a crucial role in industries such as mining, coal, and chemicals, where efficient and stable operation is essential.
The expeller is typically installed in the expeller seal section of the slurry pump. It is located in the shaft sealing area, usually near the pump casing wall and bearing section, and rotates together with the impeller to provide sealing protection. Its main function is to generate centrifugal force through the pump’s internal rotational flow, pushing the slurry out of the pump and preventing it from leaking through the shaft seal. The main role of the expeller is as follows.
Sealing Protection: Expeller works with the pump shaft’s sealing components to reduce leakage, maintaining pump integrity and reducing shaft wear for improved reliability. Reduced Seal Wear: Expeller minimizes internal pressure differences, reducing seal wear and leakage, which extends pump life. Enhanced Durability: Made from wear-resistant, corrosion-resistant alloys, the expeller ensures long-term performance in harsh environments with abrasive or corrosive slurries. Improved Efficiency: By controlling leakage, the expeller boosts pump efficiency and reduces energy loss. Lower Maintenance Costs: Compared to traditional seals, the expeller reduces wear and failure, cutting down on maintenance costs.

Based on The Multi-phase Flow Applying CFD technology to analyze and calculate the velocity and pressure fields inside slurry pumps, predicting performance parameters and optimizing designs. This includes researching multiphase flow characteristics, particle wear features, and their impact on pump efficiency, enabling the series expansion of hydraulic models.
Using finite element analysis, we calculate the stress distribution in both circumferential and radial directions within the volute under various operating conditions (including stable operation, start/stop, and variable conditions). The goal is to identify the maximum stress points and perform strength validation. This ensures that the component’s rigidity and strength meet the requirements while reducing design redundancy.
CAE technology simulates the entire pouring process, analyzing temperature, flow, and stress fields. This helps predict defects like shrinkage and porosity, enabling process optimization and improved product quality. By simulating thermal and mechanical stresses, CAE ensures slurry pump components can withstand harsh conditions, improving material selection and durability for longer pump life and minimizing shrinkage and porosity, resulting in stronger, more reliable slurry pumps with fewer maintenance needs. Continuous simulations refine casting and design processes, enabling ongoing improvements in slurry pump performance and quality across industries.
Slurry pumps and spare parts are designed using 3D models, ensuring optimized functionality, aesthetic appeal, and ease of maintenance. 3D models ensure precise fit and function of spare parts, reducing errors and production adjustments, leading to better efficiency, and helping identify potential issues in installation and operation early, ensuring smooth deployment and reducing field problems. 3D models optimize pump components for better performance, easier maintenance, and longer service life, reducing wear and increasing energy efficiency.
