INDUSTRIES SERVED: Mineral Processing, Mining
As a professional China manufacturer and supplier of slurry pump polyurethane liners, we focus on delivering wear-resistant solutions for demanding slurry transport systems. Our cast polyurethane liners combine high tear strength, elasticity, and hydrolysis resistance, helping clients reduce downtime and maintenance costs. With advanced casting equipment and strict quality control, we ensure stable parameters including hardness tolerance, tensile strength, and dimensional accuracy.
Our liners are widely used in mining, mineral processing, sand washing plants, dredging projects, and coal preparation systems. We support OEM replacement for Warman® type slurry pumps and other global brands. Whether you are a pump distributor, local agent, or industrial factory maintenance team, we provide reliable polyurethane wear parts tailored to your application environment.

- Perfect for mining operations moving fine abrasive slurries where rubber liners wear out too fast.
- Excellent in coal washing plants handling high-concentration coal-mud mixtures with minimal noise.
- Widely used in dredging and sand gravel pumps exposed to constant impact and sliding abrasion.
- Ideal for power plant ash and tailings transport lines that need corrosion and hydrolysis resistance.
- Great choice for chemical processing pumps dealing with acidic or oily slurries up to 70°C.
- Superior abrasion resistance, 3-5 times longer life than traditional rubber liners.
- Excellent corrosion resistance for acidic and alkaline slurry working environments.
- Good elasticity and impact absorption, reducing pump vibration and noise.
- High dimensional stability under high temperature (40-90℃) and heavy load Light weight design, easy to install and replace for lower maintenance time.
- Oil and radiation resistance, suitable for multiple harsh industrial scenarios.
- No bubbles or visible defects, ensuring stable pump hydraulic efficiency
- Enjoy factory-direct competitive prices that typically save customers 60-70% compared to big-brand equivalents.
- Parameter performance: better wear resistance than market average products
- Quality ranking: top tier in China polyurethane liner manufacturers with ISO certification
- Benefit from low MOQ starting at just 1 set, perfect for trials or urgent maintenance needs.
- Rely on our dedicated after-sales service with 12-month warranty, 24/7 technical support, and fast replacement parts.
- A large gold mine in Australia was facing frequent replacement of rubber slurry pump liners, with a service life of only 1 month due to high abrasive ore slurry. After switching to our ultra wear resistant Shore A 85 custom cast slurry pump polyurethane liners, the service life was extended to 5 months, reducing maintenance frequency by 80% and cutting annual liner procurement costs by 65%. Our local agent provided on-site installation guidance and after-sales follow-up, solving the client’s long-term maintenance headache.
- A dredging company in the Middle East needed slurry pump liners suitable for high temperature (up to 85℃) coastal working conditions, with strict corrosion resistance to seawater slurry. Our custom cast corrosion resistant and heat resistant polyurethane liners with Shore A 80 hardness were designed for their specific pump models, with high dimensional stability under extreme temperature. The liners have been in stable operation for 4 months without any wear or deformation, meeting the client’s high-standard project requirements.
- A chemical plant in Europe required OEM slurry pump liners for their special corrosive chemical slurry pumps, with small MOQ for trial use. We accepted their 5-piece OEM order with custom mould casting, delivered the products in 15 days, and provided free sample testing before bulk production. The liners showed excellent corrosion resistance in their working environment, and the client later signed a long-term bulk order and became our regional agent.

- Choosing the right liner doesn’t have to be complicated. First, check your slurry particle size and concentration — go for higher Shore A hardness (92-95) if you have lots of fine sharp silica.
- Next, note operating temperature and chemistry: our ether-based polyurethane handles up to 70°C continuously and resists hydrolysis far better than standard grades.
- Match the liner thickness and bonding style to your pump model and duty. Compatibility with existing OEM pump structure..
- Finally, consider total cost of ownership: although upfront price is attractive, the real savings come from longer life and fewer stops. Send us your pump curve and slurry data sheet and we’ll recommend the optimal custom solution within 24 hours.
Providing technical drawings or worn samples helps improve matching accuracy.
Polyurethane typically lasts 3-5 times longer in fine abrasive and oily slurries, with better cut resistance and smoother flow. Rubber is still good for some coarse duties, but PU wins in most modern mining applications.
