The ZJQ Series Submersible Slurry Sand Pump delivers exceptional industrial fluid handling performance, engineered specifically for rigorous mining dredging, river clearing, and industrial waste operations. Driven by an advanced pure copper motor, this heavy-duty pump offers unmatched reliability, efficiency, and exceptional structural longevity under highly abrasive environmental conditions. Its primary customer value centers on its heavy-duty wear resistance, ensuring consistent high-flow execution while significantly lowering long-term maintenance costs.
Built with a robust cast iron body and premium high-chromium alloy wear components, the pump effectively handles harsh slurries, coal slag, and dense silt. The advanced design incorporates an optional external agitator wheel that uniformly breaks up thick sediments, allowing the unit to draw heavily concentrated mixtures without clogging. Complementing this is a thickened, hollowed-out suction base that maximizes entry surface area, drastically boosting total extraction efficiency. The precision-balanced internal engineering limits noise and structural vibrations, providing a smooth user experience during extended deep-water submersion. With supported options for tailored customization, this electric sand pump serves as a versatile, low-maintenance workhorse for modern environmental dredging and industrial mineral processing lines worldwide.

Extra Sections
Functions:
-
Operates directly underwater as a submersible fluid mover, using heavy-duty mechanical agitation and centrifugal pressure to continuously lift heavy mud and particulate-laden sand without priming delays.
Advantages:
-
No Priming Needed: Submersible operation entirely eliminates the need for complex external vacuum lines or foot valve priming configurations.
-
Anti-Clogging Design: The combination of an integrated agitator and large hollow intake guarantees clog-free passage for thick solids.
