Submersible Sand Mining Dredge Pump
- Description
Submersible dredge, also called submersible slurry pump dredger, is designed and manufactured with optimized hydrodynamics technology for sand dredging and silt clearing. OCEAN Pump brand ZJQ series submersible dredge is equipped with our own specially designed submersible dredger pump, advanced high efficiency suction reamer head and the famous brand motor. All of them are integrated together to realize high dredger suction ratio, more thorough dredging and large slurry or sand output.
OCEAN Pump brand heavy duty submersible pump is made of high-chromium alloy material with good wear-resisting property and big flow passage way which is suitable for transportation of even 60mm diameter medium including mud with big solid particles, ore pulp, coal pulp and coarse sand, etc. The flexible sensing probe can realize over-heating protection, water-intake inspect protection and oil chamber protection, ensuring long and safe pump operation under abominable working conditions. Our submersible dredge features reliable, efficient and robust design, strong dredge body construction, cost saving, easy to operate and maintain. It is the best dredging equipment for small and medium scale multifunctional dredging projects.
