Core Advantages
Highly Efficient and Energy-Saving
The submersible dredge pump operates directly underwater, utilizing water pressure to assist in feeding, resulting in lower energy consumption compared to pumps that require vacuum priming.
01
Excellent Dredging Capacity
Inspired by the wide flow path and heavy-duty impeller design of dredge pumps, it can handle mixed media containing solids and fibers.
02
Strong Wear Resistance
Wetted parts are made of high-chromium alloy cast iron, specifically designed to withstand abrasive underwater media.
03
Easy Installation
No fixed pump station is required; deployment via slings or rails provides high flexibility.
04
Technical Details
Diverse Sealing Options: The submersible dredge pump can utilize a variety of sealing options, including packing seals, mechanical seals, grease-filled seals, and spiral sleeves with L-shaped rubber seals, ensuring absolute waterproofness and reliability in deep water.
Removable: The submersible dredge pump's impeller utilizes a multi-start trapezoidal thread connection, providing high torque transmission and easy assembly. An impeller removal ring is located at the rear end of the sleeve for easy impeller removal.
Applications
- Deep-sea mining
- Port and waterway dredging
- Deepwater reservoir desilting
- Caisson and foundation pit drainage
