Definition of Dredge Pump and Slurry Pump

Slurry pumps are the mechanical devices utilized for pressure-driven transport of a fluid mixture (aka slurry). The fluid mixture by and large consists of water as a liquid with solids being minerals, sand, gravel, human waste, drilling mud or most of the crushed materials.

Dredge pumps are a special category of heavy-duty slurry pumps that are utilized in the process of dredging. Portable dredge pumps tend to be smaller, but pump solids, handle abrasive slurries and perform sediment removal for maintenance dredging projects equally well (albeit on a lower level). Dredging is referred to as the process of transport of underwater sediments (usually sand, gravel, other abrasive granular materials or rocks) from one region to another (a piece of typical dredging equipment is shown in Figure 1). Dredging takes place in shallow water areas of lakes, rivers or ocean for the purpose of land reclamation, desilting, flood prevention, mining operations, creation of new ports or expansion of existing ports. Hence, various industries that utilize dredge pumps are the construction industry, mining industry, the coal industry, and oil & gas industry.

The dredge’s suction pipe connects directly to the pump casing’s sealed frontal portion and plays a crucial role in absorbing the slurry and transporting the material through the separate discharge line.

Primary selection requirements for dredge pumps

Apart from economic considerations, two primary selection considerations for dredge pump operation are no settlement of sediments in the pump and minimum amount of wear and tear in the pump due to the flow operation. The dredge pump’s discharge plays a crucial role in the overall system, as it is connected to a separate discharge line and is responsible for transporting the material through the discharge pipeline. The key design parameters to keep in mind to satisfy the primary requirements are the type of installation, critical flow rate, total discharge head, and the pump design material.

Know your slurry type:

Before moving on to estimating the design parameters of ‘your’ slurry pump, an extremely crucial step is being familiar with the material that needs to be transported. Therefore, estimation of pH and temperature of the slurry, the specific gravity of slurry and concentration of solids in the slurry is the first crucial step towards the direction of ‘your’ ideal pump selection. Dewatering pumps are essential for efficient water removal in various projects such as construction sites and mining operations, ensuring sites remain dry and operational.

Critical flow rate estimation:

Critical flow rate is the transition flow rate between a laminar and a turbulent flow and is calculated based on grain diameter (size of slurry particles), the concentration of solids in the slurry and the pipe diameter. For minimal settlement of sediments, the actual pump flow rate of ‘your’ pump should be higher than the calculated critical flow rate for your application. However, it is important to be careful with the selection of the pump flow rate as the increase in flow rate will increase the wear and tear or abrasion of the pump material and hence reduce the lifetime of the pump. Hence, for an uninterrupted performance and extended lifetime, the pump flow rate should be optimized.

Discharge head estimation:

Total discharge head is a combination of static head (actual elevation difference between the surface of the slurry source and the discharge) and friction loss in the pump. Along with dependence on the geometry of the pump (pipe length, valves or bends), friction loss is also affected by the pipe roughness, flow rate and slurry concentration (or percentage of solids in the mixture). The friction losses increase with the increase in pipe length, the specific gravity of the slurry, concentration of the slurry or the slurry flow rate. The pump selection procedure requires that discharge head of ‘your’ pump is higher than the calculated total discharge head. On the other hand, it is crucial to note that the discharge head should be kept as low as possible to reduce the pump abrasion due to slurry flow.

A separate discharge line connected to the dredge pump’s discharge can help reduce friction losses and improve efficiency by facilitating the transport of material through the discharge pipeline.

Pump power rating:

The power consumption by the dredge pump is estimated from the discharge head, flow rate and specific gravity of pumped slurry. It is critical to verify that power rating of the selected pump is higher than the calculated power consumption after taking into account reasonable variations in operating conditions.

Material selection:

Typical material used for the construction of slurry pumps are cast iron, stainless steel, and high chrome steel. Some slurry pumps come with a lining to better deal with problems of slurry abrasion. A few elastomers which are used in the lining material are natural rubber, polyurethane or neoprene. The selection of lining material depends on the operating temperature, pH of slurry and the presence of specific abrasive fluids used in the dredging process.

Type of slurry pump installation:

Based on the shaft orientation, the slurry pumps can be divided as horizontal pumps and vertical pumps with horizontal pumps having the shaft in a horizontal position while the vertical pumps have a vertically aligned shaft.

Horizontal pumps are the most common types of slurry pumps used, and hence have the advantage of ease of installation or maintenance, a wide range of selection of flow parameters and choice of design materials. However, the vertical pumps among other benefits have the advantage of requiring relatively much lesser ground space for installation.

Another method to classify the type of installation for slurry pumps is dry installation or wet installation. Dry installation pumps have the hydraulic end and the drive located outside the liquid while the wet installation pumps such as submersible pumps operate inside the sump or the slurry. The submersible pumps do not require much support structure, hence, do not occupy much space. Depending on the kind of operation and installation desired the preferred method of pump installation is decided. Certain pumps are also capable of pumping sea water and handling abrasive particles.

1.What is Submersible Slurry Pump

A submersible slurry pump for cleaning projects is a pump designed specifically for pumping and removing mud and sediment during cleaning processes. This type of pump is widely used for cleaning ponds, lakes, water tanks, industrial wastewater ponds, construction sites and other areas where accumulated sludge, sediment or debris needs to be removed. OCEAN Pump submersible slurry pumps are specifically designed for the challenging conditions faced during cleaning processes such as abrasive particles, high solids content and viscosity changes. The submersible slurry pump body is usually immersed in the liquid or slurry being cleaned, and the bottom suction port is in direct contact with the slurry, allowing efficient and effective extraction of the slurry. As a kind of equipment specially designed to handle high-concentration solid particle slurry, the submersible slurry pump provides an important transportation solution for industrial production and environmental protection.

2. How to Choose Submersible Slurry Pump for Cleaning Works

1. Determine the cleaning requirements for submersible slurry pump

When planning the cleaning tasks of submersible slurry pumps, you must first clarify the cleaning work sites, such as rivers, ports, wells, ponds, sedimentation tanks, etc. Based on this, select a pump type suitable for pumping mud or sediment. If the treated material is fine sand or silt, a conventional DMZ submersible slurry pump can be used. The bottom of the pump is equipped with numerous small holes that can filter large particles to prevent clogging while protecting the impeller and motor. If the materials to be cleaned contain large particles or grit, OCEAN Pump has developed a unique impeller and pump casing design that can smoothly pass large particles. If there is hardening or hard gravel in the cleaning site, OCEAN Pump is also equipped with a stirrer on both sides to improve efficiency. At this time, you can choose a DMD submersible slurry pump. In addition, OCEAN Pump is designed with a special sand suction head that can adapt to various mud or sediment types.

2. Evaluate the capacity of the submersible slurry pump

Choose a submersible slurry pump that matches the flow required for your cleaning work. Capacity is usually measured by the flow or discharge of the pump per unit time. The capacity units vary in different regions. Common expressions include gallons per minute (GPM), liters per second (L/s), or cubic meters per hour (m3/h). Due to the characteristics of the submersible slurry pump being immersed in liquid and having the sand suction port in direct contact with the material, its extraction efficiency is higher than that of conventional horizontal pumps. The flow here refers to the mixed flow of sand and water, in which the sand concentration generally accounts for 30% of the mixed flow. In order to increase the extraction concentration of the submersible slurry pump, OCEAN Pump has taken measures such as adding a high-pressure water gun and adding 2-3 agitators. The maximum concentration can reach 60%. OCEAN Pump will configure different solutions based on the output and time requirements provided by customers to ensure that the selected pump can effectively handle the expected amount of slurry.

3. Consider the lift and pressure requirements of the submersible slurry pump

When establishing the pressure required for the cleaning task of the submersible slurry pump, it is necessary to comprehensively consider the lift and conveying distance factors. Among them, the head refers to the vertical distance from the clean water surface to the highest discharge point, while the discharge distance represents the horizontal distance between the submersible slurry pump and the discharge point. Both of these have a significant impact on the pressure required. According to the needs of different customers, corresponding measures should be taken. For example, for some cleaning locations that only need to discharge slurry to the shore, a high-flow, low-lift pump type can be selected to meet basic cleaning needs while avoiding waste of energy and resources. However, for customers who need to transport slurry to longer distances, such as 500 meters, meters or even further, the situation is different. In this case, the head, flow rate and discharge distance need to be considered comprehensively, and the number of pumps may even need to be increased to ensure that the customer’s demand for long-distance transportation is met. OCEAN Pump will fully consider the actual situation and needs of customers when dealing with such issues. Based on the required lift, flow rate and discharge distance, we provide customers with the most suitable solution, which may include customized designs, to ensure that cleaning tasks can be completed efficiently and stably.

4. Evaluate submersible slurry pump construction and materials

Submersible slurry pumps are designed to withstand wear and tear from mud and sediment. During the cleaning process, part of the pump body is in direct contact with mud or sediment, causing the pump casing, impeller, water-absorbing plate and other flow-passing parts to be easily worn. To this end, OCEAN Pump uses durable materials to make flow parts, the commonly used high-chromium alloy Cr28, also known as A05. Special materials can be customized for special working environments, such as SS304 and SS316 stainless steel. In addition to wear problems, the seal of a submersible slurry pump is also a key indicator of the pump’s durability. 2-3 oil-lubricated double-end mechanical seals are usually used, and special structures require special design. For deep-sea sand pumps, OCEAN Pump has developed and designed special mechanical seals for high-pressure deep seas, which have won high praise from customers.

5. Consider the power source of Submersible Slurry Pump

Electric drive is a widely used drive method for submersible slurry pump. In this driving mode, the motor and the pump are coaxially integrated, and the motor shaft drives the water pump impeller to rotate, transferring energy to the slurry medium, causing it to generate a certain flow rate, thereby driving the solid matter to flow and realizing the transportation of the slurry. The advantages of electric drive are higher stability and less noise. When selecting an electric drive, the power voltage of the on-site power needs to be considered, as power voltages vary between countries. For this reason, OCEAN Pump can usually customize motors according to customer needs, such as 380V/440V, 50HZ/60HZ, etc. If power conditions are not available on site, some customers will choose to use generator sets to generate electricity. The electric-driven submersible slurry pump is easy to control, small in size, light in weight, relatively safe in installation and layout, and has no environmental problems such as hydraulic oil leakage.
Hydraulic drive is an increasingly popular driving method, and more and more customers choose to use hydraulic drive. The hydraulic drive system can provide higher torque output and is suitable for high power output occasions. Hydraulic drive can be divided into two methods: one is that some customers directly borrow the hydraulic system of the excavator to drive the submersible slurry pump. Through the control system of the excavator, precise control of the output power, speed and direction can be easily achieved; the other is One way is to use a hydraulic pump station to drive and use a diesel engine to drive an oil pump to provide power for the hydraulic submersible slurry pump.
OCEAN Pump will select hydraulic drive pumps or electric drive pumps for customers based on specific application scenarios and requirements. On the basis of comprehensively considering the advantages and disadvantages of various driving methods and application requirements, we provide customers with reasonable choices.

6. Evaluate Submersible Slurry Pump portability and installation options

Depending on the nature of the cleaning job, OCEAN Pump selects a pump that is either portable or permanently installable. When making purchase decisions, OCEAN Pump fully considers factors such as weight, size, and ease of installation. When selecting a submersible slurry pump, you also need to consider the scale and depth of the cleaning task. For small cleaning tasks, corresponding small pump models can be selected to fit into narrow operating spaces. For deeper cleaning tasks, you can choose a pump with a longer cable to meet the depth requirements. In addition, OCEAN Pump also provides customers with one-stop service, not only providing submersible slurry pumps, but also supporting winches, cable drums, cable conveyors, control cabinets and other facilities, which improves the efficiency of customers in finding solutions and provides complete services. Save time and business opportunities for customers.
