Premium Frame Plate and Cover Plate Liners from a leading China factory. As professional suppliers, we provide high-chrome and rubber wear parts to protect your pump casing and reduce maintenance costs.
The Frame Plate Liner and Cover Plate Liner are critical wet-end wear components specifically engineered for high-performance slurry pumps. Often referred to as the rear and front liners, these precision-engineered parts form the internal casing surfaces that face the direct impact of abrasive slurries. By acting as a sacrificial protective layer, they shield the pump casing from catastrophic wear and maintain the optimal hydraulic profile required for efficient fluid transport.
At CNSME Pump, we specialize in manufacturing premium Frame Plate and Cover Plate Liners that are fully interchangeable with Weir Warman designs. Whether your application demands the extreme hardness of high-chrome white iron or the impact resilience of natural rubber, our liners are designed to maximize equipment uptime and significantly lower overall maintenance costs across mining, mineral processing, and dredging operations.
| Component Types | Frame Plate Liner (Rear) & Cover Plate Liner (Front) | Compatibility | Fully interchangeable with Warman standards |
|---|---|---|---|
| Chrome Alloy | High Chrome White Iron (A05, A07, A49) | Chrome Hardness | HRC 58–65 |
| Rubber Material | Natural Rubber (R55) & Specialized Elastomers | Polyurethane | High-grade wear and corrosion resistant PU |
| Manufacturing | Precision Casting & CNC Machining | Application Fields | Mining, Dredging, Power Generation |
| Design Focus | Hydraulic Efficiency & Wear Resistance | Replacement Cycle | Sacrificial layer for easy maintenance |

| Comparison Metric | Standard Cast Liners | CNSME Premium Liners |
|---|---|---|
| Wear Life Cycle | Short to Medium | Extended (High-Chrome) |
| Maintenance Frequency | High (Frequent Stops) | Low (Optimized Intervals) |
| Hydraulic Efficiency | Moderate Loss over time | High (Precision Profile) |
| Installation Time | Variable Fitment | Fast (CNC Precision) |
| Total Cost of Ownership | High (Frequent Replacement) | Lowest (Long-term Value) |
The Frame Plate Liner is installed on the frame side (rear) of the pump, while the Cover Plate Liner is installed on the suction/cover side (front). Together, they protect the internal pump casing from abrasive wear.
High Chrome is best for highly abrasive, coarse particles (e.g., sand, mining ores). Natural Rubber is superior for fine, sharp particles and applications requiring high impact resistance.
Yes, our Frame and Cover Plate Liners are engineered to be fully interchangeable with Warman standards, ensuring a perfect fit without modification.
Our high-chrome white iron liners typically achieve a hardness of HRC 58–65, providing exceptional resistance to sliding abrasion.
Liners act as a sacrificial layer. Replacing only the liners is significantly cheaper and faster than replacing the entire structural casing, reducing overall maintenance costs.
They are widely used in mining, mineral processing plants, power generation (ash handling), and large-scale dredging projects.

High Head Slurry Pump: What to Know
The high head slurry pump features large‑diameter impellers, slow rotational speeds, thick wear‑resistant liners, and externally ribbed casings. It can handle high‑pressure transport of tailings, ash, and other high‑solids media for extended periods. Its optimized flow passage design and sealing options (gland seal, expeller, or mechanical seal) significantly extend wear life and reduce operating costs. Compared with standard slurry pumps, a high head pump often accomplishes long‑distance or high‑lift duties with a single unit, reducing the need for multiple pumps in series.
