Dynamic Balance Sealing System Prevents Water Ingress The ZJQ pump features an upgraded pressure-balanced mechanical seal design. It effectively balances internal and external pressure differences of the oil chamber under deep water and fluctuating water pressure, avoiding seal extrusion, deformation and water leakage faults that commonly occur in ordinary submersible pumps. This professional sealing technology greatly improves underwater operation safety and extends the service life of sealing components.

　　Full-Range Intelligent Motor Protection Built-in professional monitoring modules for overheat, overload, phase loss, oil chamber leakage and water penetration. Once abnormal working conditions occur, the pump will automatically power off and alarm, preventing motor burnout and equipment damage. The F-class high-temperature resistant motor winding ensures stable output under heavy-load and high-temperature continuous operation.

　　Reinforced Alloy Flow Parts for Ultra-Long Service Life All wetted components including main impeller, pump body and bottom agitator are precision-cast from high-hardness high-chromium alloy. It resists continuous scouring of hard sand, ore particles, coal slag and abrasive sediment, achieving several times longer service life than ordinary cast iron submersible pumps and reducing frequent replacement downtime.

　　Wide Flow Channel Anti-Clog Hydraulic Performance The optimized large-diameter unobstructed flow channel allows smooth passage of large solid particles up to 80% of the minimum channel size. It effectively avoids blockage caused by mixed silt, gravel and floating debris, maintaining stable flow and concentration during long-cycle underwater slurry transportation.

　　Professional Application Scenarios

　　24/7 tailings pond underwater discharge, long-term reservoir sediment accumulation cleaning, continuous thermal power plant ash slurry circulation, seasonal river flood sediment removal and harsh working condition underwater slurry fixed-point conveying projects.
