Why Lined Slurry Pumps Fail in Real Applications
Handling abrasive slurry is not just about pumping liquid; it’s about surviving wear, temperature, and system instability.
Many conventional pumps struggle with:
- Rapid wear from solid particles
- Performance loss under high temperature
- Instability caused by pressure fluctuation and cavitation
- Increased maintenance due to material limitations
HB Series Stainless Steel Slurry Pump Solutions
It primarily addresses the issue of shortened pump service life caused by wear, corrosion, or blockages due to solid particles in the mining and metallurgical industries.
✔ Resists abrasive wear from particle-laden slurry (0.3–1 mm)
✔ Maintains stability under high temperature up to 180°C
✔ Strong metal structure reduces risks of cavitation and pressure impact
✔ Wide chemical compatibility for industrial and chemical processes
✔ Clean and anti-static design for safer and compliant operation
✔ Compatible with existing UHB systems – easy integration without redesign
✔ Longer service life with reduced maintenance frequency
Advantages of the Abrasive Slurry Pump
High Temperature Structural Integrity
Eliminates liner creep and deformation. Single-piece stainless steel casting ensures stable operation in abrasive slurry processes up to 180°C.
Broad Chemical/Solvent Compatibility
Prevents swelling and cracking. Provides comprehensive resistance against strong oxidizers and organic solvents where non-metallic materials typically reach their limits.
Superior Hard-Particle Resistance
Handles sharp, aggressive solids. The rigid metallic structure resists erosive wear and high-velocity fluid impact better than soft polymer linings.
Extended Mean Time Between Maintenance (MTBM)
Lower Total Owned Cost. Eliminates common lining failures like delamination or blistering, ensuring long-term reliability in heavy-duty industrial applications.
parts for Abrasive Slurry Pump
Featuring all-stainless-steel flow-through components, a semi-open impeller, and a high-rigidity structural design, the HB series maintains excellent resistance to wear and clogging, as well as stable operation even under complex operating conditions. The following are the main core components:
- Pump Housing (High-Rigidity, Pressure-Resistant Construction)
- Constructed from 304, 316L, or duplex stainless steel (customizable), the housing features high overall rigidity and excellent resistance to pressure and impact. Its smooth internal flow passages effectively reduce turbulence and erosion wear.
- Pump Cover (Reliable Sealing and Maintenance-Friendly Design)
- Precision-machined stainless steel construction ensures stable sealing performance and easy disassembly, effectively reducing maintenance complexity and downtime.
- Impeller (Semi-Open Anti-Clogging Design)
- Features a semi-open impeller with thickened blades and an optimized flow path design, capable of handling particles ranging from 0.3 to 1 mm in size. This reduces the risk of clogging and enhances the pump’s ability to handle slurries containing solids.
- Protective Covers / Wear Parts (Wear-Resistant, Replaceable Design)
- Critical wear parts feature a wear-resistant stainless steel design. The modular structure facilitates easy replacement, effectively extending the overall service life of the unit and reducing maintenance costs.
- Shaft and Bearing Assembly (Stable, Low-Vibration Operation)
- A high-strength shaft combined with heavy-duty bearing support, optimized for dynamic balance, reduces vibration and runout, ensuring long-term stable operation.
- Sealing System (Reliable Leak-Proof Design)
- Our proprietary high-performance mechanical seals (with multiple customizable options) are suitable for slurry and chemical applications, effectively preventing leaks and enhancing operational safety.
- Base Structure (Installation-Compatible Design)
- The rigid base structure is compatible with UHB pump installation systems, eliminating the need for modifications to piping or foundations and ensuring easy installation.

Material Performance Comparison
Material Properties Overview
| Material | Corrosion Resistance (PREn) | Hardness (HB) | Application |
|---|---|---|---|
| 304 Stainless Steel | 18–20 | 150–180 | General industrial fluids |
| 316L Stainless Steel | 24–26 | 150–190 | Mild corrosive and chemical media |
| Duplex 2205 | 34–38 | 250–280 | Chloride-containing environments |
| Super Duplex 2507 | 42–45 | ≥300 | High corrosion and severe abrasion conditions |
Note: Higher PREn values indicate stronger corrosion resistance, making 2507 and 2205 suitable for more aggressive and demanding slurry applications.
Reference for the PREN Calculation Formula:PREn=%Cr+3.3×(%Mo+0.5×%W)+16×%N
