The slurry pump is equipped with a triple composite sealing system: auxiliary impeller dynamic seal + packing seal + flushing water seal, designed for harsh working conditions with high solid content, strong abrasion and easy crystallization.
During operation, the high-speed rotating auxiliary impeller generates reverse centrifugal pressure to offset internal slurry overflow pressure and reduce seal load fundamentally. The middle soft packing provides auxiliary sealing, dustproofing and vibration reduction. External flushing water forms a continuous clean water barrier in the seal gap, preventing fine sand and solid particles from entering the shaft gap and avoiding shaft abrasion, seal burning and slurry leakage.
This sealing system allows higher operation tolerance for short-time dry running, material shortage and liquid level fluctuation. It effectively eliminates slurry leakage, keeps clean on-site environment and improves long-term sealing stability.
