The seal prevents the leakage of slurry into the motor compartment. It is a critical component for ensuring the longevity of the pump.

Discharge Pipe:

The discharge pipe is the outlet for the pumped slurry. It is usually connected to a pipeline or hose for transporting the material to its destination.

Identifying the right pump

• A dewatering pump sucks in water through an inlet valve and ejects it from a discharge valve. They have an inlet size ranging in size from 1 to 4 inches. A 4-inch dewatering pump will finish a job 4 times faster than a 1-inch pump.

• A semi-trash pump is used to pump clear or slightly muddy and sandy water. You will want to use a hose with a strainer so the hose doesn’t get clogged with items too big to pass through.

• A trash pump is made to handle debris and solids, such as leaves, pebbles and twigs. These pumps have larger impellers and leave debris intact. Use a hose with a strainer for a trash pump, so items that are too large don’t enter.

• Diaphragm pumps are most commonly used to pump sludge and extremely abrasive liquids. The pump has a diaphragm which is pushed up and down, creating a vacuum effect that draws in water.

In practice, we recommend connecting a rubber hose directly to the submersible slurry pump outlet. For long-distance transport, HDPE pipes or steel pipes can be utilized to guarantee stability and efficiency in the material transfer process.

3.Understanding the Key Parameters of Submersible Slurry Pumps

Understanding the important parameters of submersible slurry pumps is crucial for selecting the right pump for specific applications and ensuring optimal performance. Below are some key parameters to consider:

3.1  Flow Rate

Flow rate is typically measured in cubic meters per hour (m³/h) or gallons per minute (GPM), determining the pump’s capacity to move dredged materials. It is important to note that the flow rates listed in the DMZ submersible slurry pump specifications refer to clean water mixed flow. OCEAN Pump is equipped with advanced flow testing equipment capable of accurately measuring the flow rates of various submersible slurry pump models and can provide different flow rate levels tailored to customer needs.

3.2  Head Height

Head height is measured in meters (m) or feet (ft) and indicates the maximum vertical distance the submersible slurry pump can lift dredged materials. This parameter is essential for determining the pump’s ability to transport materials to the desired discharge point. Head height refers to the vertical distance from the clean water surface to the highest discharge point, while the distance refers to the horizontal distance between the submersible slurry pump and the discharge point. Both factors significantly impact the required pressure. Depending on customer requirements, appropriate measures should be taken. If the head is too low, it may result in insufficient fluid transport; conversely, if the head is too high, it can increase energy consumption and costs.

3.3 Solid Handling Capacity

Submersible dredge pumps are designed to handle solids of certain sizes and concentrations, such as sand, gravel, or sludge. The impeller design and casing material of submersible slurry pumps must withstand the abrasive nature of dredged materials. Typically, submersible slurry pumps are categorized into open and closed structures. Open-structure impellers provide higher flow rates and lower heads, making them easy to clean and suitable for high-output barge operations that do not require discharging material to the shore. In contrast, closed-structure impellers have smaller flow paths, limited flow rates, but higher heads with reduced wear, making them suited for extracting fine sand and mud from coastal areas where clogging is less of a concern.

To combine the advantages of both designs, OCEAN Pump’s R&D department has developed semi-open and three-vane impeller structures, ensuring both flow and head while maintaining slurry passage capability. This innovation allows large particle submersible dredge pumps to exhibit significant advantages in flow performance and wear resistance. In terms of materials, the flow components of OCEAN Pump’s submersible slurry pumps are made from high-chromium wear-resistant alloys, with custom options in stainless steel or other materials available based on specific slurry compositions.

3.4 Power Requirements

When selecting a pump, power supply and actual demand are two critical considerations. An improper power selection can lead to inadequate flow rates and head, adversely affecting the submersible slurry pump’s operational efficiency. Conversely, an excessively high power rating can increase energy consumption and operational costs while imposing unnecessary strain on the equipment, impacting its lifespan.

Additionally, it is essential to consider the differences in industrial voltage frequencies across various countries. For instance, the commonly used industrial voltage frequency in our country is 380V/50Hz, while some countries use 440V/60Hz. To ensure stable operation, OCEAN Pump thoroughly assesses the voltage frequency of the customer’s location prior to selection, customizing solutions according to local conditions. OCEAN Pump also offers comprehensive services, including matching variable frequency drive (VFD) control cabinets. With VFD control cabinets, users can easily adjust the flow rate and head of their submersible slurry pump, ensuring safe motor operation and meeting diverse operational needs. This not only enhances pump utilization and energy savings but also reduces operational costs.

By understanding these key parameters, engineers and project managers can select the most suitable submersible slurry pump for specific dredging applications, ensuring efficient and effective material removal while minimizing operational challenges and downtime.
