- Choosing the right pump for your slurry is critical to getting the most out of it. Basic pump components such as impeller size and design, materials of construction and discharge configuration must be considered to ensure that the pump can withstand the wear caused by abrasive slurries. Compared to low-viscosity liquid pumps, target=_blank title=Slurry Pump>slurry pumps are typically larger and often require more horsepower to operate because they are less efficient. Bearings and shafts must also be more robust and durable.
- Especially when the dredging depth reaches 20m or more, the above situation will be more obvious. The use of underwater pumps can effectively improve the above situation. The lower the installation position of underwater pumps, the smaller the suction resistance and vacuum, which can obviously reduce the losses during the work and improve the working efficiency. The installation of underwater pump can effectively increase the dredging depth and improve the ability to transport sediment.
- Compared to standard centrifugal pumps, centrifugal pumps optimised for slurry pumping usually have the following features.
- - transport solids hydraulically
- On the other hand, if the slurry is not only abrasive but also has a low pH, then a duplex stainless steel construction is preferable. This material is best suited for slurry pumps to withstand harsh materials (such as acids) while still having a high Brinell hardness.
- It is important that the pump you choose has components that will not wear out from abrasive slurries.
- The winch dredger is usually equipped with a hull-mounted dredge pump, which has an impeller centered at or below the draft line for further production and improved suction efficiency.
- Despite the complexity of internal flow patterns, the overall performance of dredge pumps is predictable.
- It is important that the pump you choose has components that will not wear out from abrasive slurries.
- The most important thing here is to determine the pump power required to deliver a specific fluid flow at the desired or required differential pressure. Consider the following.
- A clear clean fluid supplied from an external source is normally used which is delivered to the main sealing surface on the fluid side of the sealing process. By using a closed gap throat bushing, the stuffing box can be back-pressurised to a higher pressure, ensuring that the flushing fluid does not flash across the seal face.
- Despite the complexity of internal flow patterns, the overall performance of dredge pumps is predictable.
- A typical pump solution for this application is to install a hard metal >slurry pump to withstand these types of conditions. Hard metal pumps need to be able to withstand the most severe abrasive slurry service and they also need to be designed to be extremely easy to maintain and safe.
- The dredge pump is designed to draw sediment, debris and other hazardous materials from the surface layer into the suction pipe and transport the material through the pipe to the discharge site. The pump must be able to handle common solid debris of various sizes that can pass through the pump, thus minimizing the downtime required for cleaning.
- Longer maintenance intervals
- Determine the perfect combination of slow pumping (to reduce wear) and fast pumping to prevent solids from settling and clogging.
- One problem with centrifugal pumps is that the velocity and shear forces within the pump may damage the slurry/solids. Typically, twin-screw pumps cause the least damage to solids in the slurry.
- - Smaller, more efficient tank - Because the motor is cooled by the surrounding liquid, the submersible slurry pump can be started up to 30 times per hour, resulting in a smaller, more efficient tank.
- >Slurry pump impeller is one of the most important parts of centrifugal slurry pumps. Depending on the application, slurry pump impeller selection is crucial to slurry pump performance. Slurry applications can be especially hard on the impeller of slurry pumps because of their abrasive nature. In order slurry pumps operates efficiently and stand up to the test of time, impeller has to be selected properly for slurry pumps.
- Discharge ports can be placed at 45 degree intervals and oriented in up to 8 different positions depending on your needs.

- Slurry Pump Impeller Type
- When pumping slurry in wet sand applications, we must evaluate the abrasive particles flowing through the piping and then assess how they affect the slurry pump. If the pump is lined with poor quality rubber, the particles will not rebound effectively and, as a result, the rubber will begin to break down. The air shavings then begin to accelerate and negatively impact the efficiency of the pump, often leading to turbulence.
- The size and nature of the solids in the liquid: The size and nature will affect the amount of physical wear on the pump and its components, and whether the solids will pass through the pump without being damaged.

- >Dredge pumps are a special category of pumps used in the dredging process. Dredging is the process of transporting submerged sediments (usually sand, gravel or rock) from one area to another. Dredging takes place in the shallow waters of lakes, rivers or seas for land reclamation, dredging, flood control, new harbours or expansion of existing harbours. The various industries that use dredge pumps are therefore the construction industry, mining, the coal industry and the oil and gas industry.
- The terms flushing and quench, often seem to be confused or misused when discussing seal support schemes for , slurry pumps, . As the concepts of a mechanical seal cartridge and a filled seal cartridge are slightly different, I will discuss them separately and in turn.
- Although the focus of slurry pumps is often on the size and percentage of solids to be pumped, in many applications corrosion resistance is also an important factor in material selection. In such cases, the material chosen must provide adequate resistance to erosion and corrosion.

- Stainless Steel, Duplex Stainless Steel, Ductile Iron, Grey Iron, etc. We can also provide natural rubber, elastomer rubber parts and pumps.
- A dredge pump contains a pump casing and an impeller. The impeller is mounted in the pump casing and connected to the drive motor via a gearbox and shaft. The front part of the pump casing is sealed with a suction cover and connected directly to the suction pipe of the dredger. The discharge port of the dredge pump is located near the top of the dredge pump and is connected to a separate discharge line.
- Larger impellers made of more material. This is to compensate for the wear and tear caused by abrasive slurries.
- Firstly, analysing your duty helps us to determine whether you are using the type and size of pump best suited to your needs. Cavitation can occur due to surges; a very effective way to solve this problem is to install a choke on the pump head to increase the pressure on the casing, which then absorbs the surge, or to add a choke to the output to reduce the surge.
- - Keeping clean catch basins clean from solids
- To reduce component wear, most centrifugal slurry pumps run at fairly low speeds - typically less than 1200 rpm. Find the optimum position that allows the pump to run as slowly as possible but fast enough to prevent solids from settling out of the slurry deposit and clogging the lines.
