As a leading manufacturer with over 25 years of experience (established in 1998), Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-quality industrial filtration belts. Our Polyester Sludge Press Belt High Tensile 5000N/5cm is engineered to deliver exceptional performance in solid-liquid separation processes. With an annual export value of US$5-10 million and a global market presence spanning North America, Europe, Southeast Asia, and beyond, we are committed to providing reliable filtration solutions that enhance operational efficiency and reduce downtime. This belt is designed to withstand the most demanding sludge dewatering applications, ensuring consistent output and long service life.
The core of this product lies in its high tensile strength of 5000N/5cm, which allows it to handle heavy sludge loads without stretching or tearing. The 50μm filtration precision effectively captures fine particles, achieving a clear filtrate and a dry cake. Made from 100% polyester material, the belt offers excellent resistance to chemicals, abrasion, and moisture, making it suitable for municipal wastewater treatment, mining, food processing, and other industries. Below we detail the key features and specifications.
Key Features & Advantages
- High Tensile Strength (5000N/5cm): Ensures the belt maintains dimensional stability under high pressure, reducing elongation and preventing premature failure.
- Precision Filtration (50μm): Optimized for fine solid-liquid separation, delivering a high-quality filtrate and a drier cake, which lowers disposal costs.
- Durable Polyester Material: Resistant to chemicals (acids, alkalis, solvents), UV degradation, and microbial attack, extending the belt's operational life.
- Superior Drainage Design: The weave structure allows rapid water drainage, improving dewatering efficiency and reducing cycle times.
- Customizable Dimensions: Available in various widths, lengths, and joint types (spiral, pin seam, or endless) to fit any belt press model.
- Low Maintenance: The robust construction and easy-to-clean surface minimize downtime for cleaning and repairs.
- Consistent Tracking: Straight edges and uniform tension distribution ensure stable belt tracking, reducing wear on press rollers.

Frequently Asked Questions
1. What is the recommended maximum operating pressure for this belt?
The belt is designed to handle typical dewatering pressures up to 6-8 bar (depending on the press design). For higher pressures, we can supply a reinforced version with increased tensile strength.
2. Can this belt be used for food processing applications?
Yes, the polyester material is food-grade safe and can be used in applications such as fruit juice, vegetable oil, and starch dewatering. Please inform us about your specific food contact requirements.
3. How do I determine the correct belt length and width for my press?
You can measure the existing belt or provide the press model number. We also offer a measuring guide. Alternatively, we can send a technician to your site (for large orders) or work with your drawings.
4. What joint types are available, and which one is best?
We offer spiral link (clipper) joints, pin seam (alligator) joints, and endless (woven) belts. Endless belts are strongest but require press disassembly. Pin seam joints are easy to install and suitable for most machines. Our sales team can recommend the best option based on your press type.
5. What is the typical lifespan of this belt?
Lifespan depends on operating conditions, but under normal municipal sludge dewatering, our belts typically last 6-12 months. With proper maintenance (regular cleaning, avoiding sharp objects), some customers have achieved over 18 months.
6. Do you provide samples for testing before bulk order?
Yes, we can provide a small sample (e.g., 30x30 cm) for you to test filtration efficiency and compatibility. We also offer trial belts at a discounted price for new customers.
7. What is the minimum order quantity (MOQ)?
Our standard MOQ is 1 piece for custom sizes. For standard sizes in stock, we can accept smaller quantities. Please contact us to discuss your specific needs.
8. How is the belt packaged for shipping?
Each belt is rolled on a core, wrapped in waterproof plastic, and packed in a sturdy carton or wooden crate (for large sizes). We also add edge protectors to prevent damage during transit.
