What is the Dredge Pump and How to select it for Work?

 

How do dredge pumps work?

Pansto dredge pump  contains a pump casing and an impeller. The impeller is mounted inside the pump casing and is attached to the drive motor via gearbox and shaft. The frontal portion of the pump casing is sealed using a suction cover, connecting directly to the dredge’s suction pipe. The dredge pump’s discharge is positioned near the top of the dredge pump and is connected to a separate discharge line.

The impeller is considered the core of a dredge pump and is similar to a fan that forces out air creating a centrifugal suction force. At the suction pipe, this vacuum absorbs the slurry and transports the material through the discharge pipeline.

Types of Dredging Pumps

Horizontal Gravel Pump

Horizontal Sand Gravel Pumps  are designed for handling abrasive materials and large volumes of sand. They are typically installed on a dredging platform such as dredger or barge, and connected to a suction and discharge pipeline.

Submersible Dredge Pump

Submersible Dredge Pumps  operate underwater directly at the dredging site. They are versatile, making them suitable for various underwater dredging tasks.

How to select Dredge Pump

Type of Material

Identifying the material to be dredged is crucial. Besides sand, you may encounter silt, mud, gravel, and debris. Selecting a pump that can handle a variety of materials ensures smooth operation and optimal performance.

Flow Rate Goals

Determine the volume of material that needs to be moved per minute. Higher flow rate requirements necessitate more powerful pumps to meet project demands efficiently.

Pipeline Length

The length of the pipeline affects the power requirements of the pump. Longer distances necessitate more robust pumps to achieve greater pressure, ensuring effective slurry movement but also resulting in higher energy consumption.

Elevation Changes

Elevation variations in the pipeline affect the pump’s power needs. Significant elevation increases demand stronger pumps to overcome gravitational forces and maintain steady flow.

Density and Viscosity

The density and viscosity of the slurry influence the pump’s workload. Heavier and more viscous mixtures necessitate pumps designed to handle increased stress without compromising performance.

Abrasion Resistance

Sand and water mixtures are highly abrasive and can quickly wear down equipment. Selecting a pump with high abrasion resistance ensures durability and reduces maintenance costs. Look for pumps made from wear-resistant materials and designed to withstand harsh environments.
