Hydraulic Submersible Sand Pump Product Introduction

1. Brief Overview

2. Core Structural Advantages

1. Hydraulic Drive System
   Equipped with heavy-duty hydraulic motor as power source, no underwater electric components. It eliminates electric leakage risks, making it safe for deep water, offshore and flammable construction environments. It delivers stable torque and strong suction power under heavy load.
2. Integrated Agitator Cutter
   A rotary stirring cutter is installed at the pump bottom. It stirs up compacted mud, hard silt and stacked gravel continuously, raising solid concentration of pumped medium and preventing blockage effectively.
3. Wear-resistant Flow Parts
   The impeller, pump casing and wear liner are cast with high-chromium alloy material, featuring excellent anti-abrasion performance to resist long-term impact and friction of sand, stone and mineral slag, extending service life greatly.
4. Full Submersible Sealing Structure
   Double-layer mechanical sealing structure prevents water and sediment from penetrating into the hydraulic motor. The whole pump can work completely under water without air cavitation, with reliable self-priming capacity.
5. Large Unobstructed Flow Channel
   Wide internal passage allows passing large solid particles, avoiding clogging by branches, broken stones and agglomerated mud during continuous pumping work.

3. Main Performance Features

• No external power cables required, highly suitable for field construction without power supply;
• Simple installation: directly connected to excavator hydraulic circuit for quick assembly and disassembly;
• Strong suction capacity, solid volume concentration of pumped medium can reach 40%-70%;
• Wide application range of working depth, stable operation under deep water;
• Low failure rate, easy maintenance and low operation cost.

4. Typical Application Scenarios

• River, lake and channel dredging & silt removal
• River sand extraction and offshore sediment cleaning
• Construction foundation pit mud cleaning
• Sewage tank, sedimentation tank sludge pumping
• Mining tailings slurry transportation
• Flood control sediment clearing and port dredging

5. Standard Matching Modes

1. Excavator-mounted type: Matched with 12-36 ton excavators, ideal for mobile on-site dredging;
2. Independent hydraulic station type: Equipped with separate hydraulic power unit for fixed long-term underwater pumping on ships or pools.
