What Are Double Shell Dredge Pumps?

Double shell dredge pumps are specially designed to handle high-head situations, which means they can effectively manage the complexities involved in moving materials that are located at significant vertical distances. With two shells working fully in tandem, these pumps are built to enhance efficiency and reliability, particularly in tough work environments.

High-Head Dredging Applications

Characteristics of High-Head Situations

• Increased Vertical Lift: High-head dredging requires significant lifting of materials.
• Long-Distance Transport: Often, materials must be moved over longer horizontal distances as well.
• Heavy Material Handling: This may include transporting slurries, mud, and sediment without losing efficiency or effectiveness.

When to Choose a Double Shell Dredge Pump

So, when should you choose a double shell dredge pump for high-head dredging applications? Below are key scenarios and factors that influence this decision:

1. Depth of Dredging Operation

• Greater Depth: If you are working in water depths exceeding 20 feet and need to transport materials to significantly elevated areas, a double shell dredge pump becomes necessary.

2. Material Characteristics

• Viscous or High-Solid Content: For operations involving thick mud or slurry, these pumps can handle the increased resistance with ease.

3. Distance to Disposal Site

• Long Distances: When materials have to be pumped over longer distances, the double shell design ensures consistent pressure and flow rate.

4. Reliability and Maintenance

• Durability: If your operations require extended uptime with minimal maintenance, a double shell dredge pump is the better choice due to its robust construction.
