Key Technical Advantages

　　No Suction Limit & Deep-Water Operation Capacity Operating completely submerged, the ZJQ slurry pump eliminates suction loss and cavitation issues common with horizontal pumps. It supports deep-water operation up to 20 meters, ensuring stable sediment extraction even in deep reservoirs, river channels and tailings ponds, delivering more thorough dredging results.

　　Built-In Stirring Impeller for High-Concentration Pumping Fitted with a bottom agitator impeller, the pump stirs up settled compacted sludge and deposited sand, suspending solid particles evenly around the pump inlet. This design enables continuous pumping of high-density slurry without auxiliary equipment, greatly improving single-time conveying concentration and project efficiency.

　　Ultra-Wear-Resistant High-Chrome Alloy Wet End All wetted components including main impeller, pump casing and stirring blade are cast from high-strength high-chromium alloy. The exceptional anti-scour and anti-abrasion properties resist long-term impact from hard sand, ore grains and coal slag, significantly extending service life and reducing frequent spare-part replacement.

　　Multi-Level Motor Safety Protection System Featuring dual mechanical seal structure plus multiple protective functions including overheat protection, overload protection, water leakage and oil chamber monitoring. The F-class insulated motor ensures safe 24-hour continuous operation in muddy, abrasive and humid underwater environments, effectively preventing motor burnout and sudden downtime.

　　Flexible & Cost-Effective Field Deployment Integrated compact structure requires no pump house, no foundation fixation and no pre-water filling. It can be freely positioned, floated or fixed underwater, adapting to fluctuating water levels and narrow construction spaces. Simple installation and maintenance greatly reduce civil engineering and labor costs.

　　Typical Application Scenarios

　　River and lake deep dredging, reservoir sediment cleaning, mine tailings pond underwater discharging, sand mining and gravel extraction, thermal power plant ash slurry removal, sewage pond sludge disposal, port waterway desilting and high-concentration industrial slurry transportation.

　　Factory Quality & Global Service

　　Every ZJQ submersible slurry pump undergoes strict hydraulic performance testing, wear-resistance aging and continuous underwater operation tests before delivery. We provide customized power, caliber and sealing configuration solutions, complete spare parts supply and professional after-sales technical support for global dredging contractors, mining enterprises and industrial pump distributors.
