This Frame Plate Seal Ring is compatible with full series of slurry pumps including AH, HH, M and L models. It is a key annular sealing part installed between the pump frame plate and pump casing. Molded precisely with high-elastic rubber and composite wear-resistant materials, the ring features standard roundness, accurate size and excellent resilience to achieve tight and gap-free fitting after installation. Designed for severe working conditions with high sediment, solid particles and corrosive slurry, the seal ring effectively blocks assembly gaps, prevents slurry leakage, sand and impurity ingress, and eliminates common failures such as internal fluid channeling and pressure loss. It also provides outstanding cushioning, vibration resistance and aging resistance to avoid sealing loosening caused by operational vibration and reduce metal component wear. Widely used in mining, metallurgy, thermal power, chemical industry and environmental desulfurization, this standard interchangeable seal ring can directly replace original parts with easy installation and strong compatibility, serving as an essential accessory for daily pump maintenance and replacement.

 Core Product Advantages 

(1) High Elastic Sealing & Stable Pressure Performance Featuring excellent elasticity and toughness, the ring fits closely under operating pressure and adapts to equipment vibration and pressure fluctuations. It maintains stable sealing performance for a long time, effectively solving common problems such as slurry leakage, water seepage, pressure drop and air intake, and keeping stable pumping efficiency.

 (2) Excellent Wear Resistance & Long Service Life Made of specially formulated wear-resistant rubber composite materials, the product resists slurry scouring and particle friction without easy deformation or damage. Optimized for high-abrasion slurry pump working conditions, its service life is greatly extended compared with ordinary seal rings, reducing replacement frequency and maintenance costs. 

(3) Corrosion & Aging Resistance for Complex Conditions It delivers outstanding acid, alkali and oxidation resistance, adapting to acidic, alkaline, high-humidity and dusty environments. It will not harden, crack or age under high and low temperature conditions, maintaining stable sealing performance during long-term continuous operation with strong environmental adaptability. 

(4) Dust & Impurity Prevention to Protect Pump Parts The seal ring tightly blocks assembly gaps and prevents sand, slag and solid impurities from entering the internal sealing area. It avoids abrasion to precision parts such as frame plates and shaft sleeves, reduces internal pump wear, and extends the service life of the entire pump assembly. 

(5) Standard Universal Size & Easy Maintenance Manufactured with standard industrial dimensions, it is fully compatible with mainstream slurry pump models. It can directly replace original parts without modification, greatly simplifying installation and replacement. It effectively reduces equipment shutdown time, improves production efficiency and lowers overall operating costs.
