The high-pressure pump sent the water that larger than the mud pump pressure to the leakproof packing. Then protect the packing. Otherwise, it is easy to make the seal part wear. But the wear-resistant slurry pumps can complete the transportation work independently, which not need to equip other auxiliary equipment.

- What is a dredging pump?
- Consider the impeller. Slurry pumps must have thicker vanes than water pumps to prevent wear. Due to the increased thickness, there will be fewer vanes, otherwise the passages will be too narrow and will affect the performance of the pump. The impeller should have a large enough passage so that the largest solid particles can pass through without clogging.
- 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.

- The FGD process begins when the limestone feed (rock) is reduced in size by crushing it in a ball mill and then mixed with water in a slurry supply tank. The slurry (approx. 90% water) is then pumped into the absorption tank. As the consistency of the limestone slurry tends to change, suction conditions can occur which can lead to cavitation and pump failure.
- For pumping abrasive slurries, these types of pumps can also be made from specialised high-wear alloys. Hardened stainless steel is also a common choice for abrasive slurries.

- All manufacturers are consistently involved in product development in the long and short term. Customers should expect to benefit from these developments in a number of ways: increased efficiency, increased reliability, reduced operating costs, or a combination of both.
- In a word, the wear-resistant properties of the slurry pumps are stronger, and the ability to convey particles is also stronger. Generally, the capacity of the slurry pump is larger than the mud pump, which is mainly used for coal and metal ore washing. The mud pumps are more suitable for abrasive slurry is not very strong.
- - Keeping clean catch basins clean from solids
- - Reduced space requirements - Since submersible slurry pumps operate directly in the slurry, they do not require any additional support structures.
- 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.

- Choosing The Right Slurry Pump For Your Application
- Step 1
- How to choose a slurry pump?
- 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.
- Slurry Pump
- There are three different >types of slurry pump impellers; open, closed, and semi-open. Each has its own strengths and weaknesses, depending on the application. Some are better for solids handling, others are better for high efficiency.
- Compared to standard centrifugal pumps, centrifugal pumps optimised for slurry pumping usually have the following features.
- Slurry Pump
- As described below, there are several , types of pumps, that are suitable for pumping slurries. However, before considering which technology to use, we must address several key issues.
- 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.
- Reduced inventory
- The design of the slurry pump is critical to ensure that the abrasive and often corrosive aspects of the slurry do not damage the impeller. In addition, slurries and sludges may contain large amounts of unforeseen solids, which will inevitably clog many types of pumps. Since most centrifugal pump impellers have very tight tolerances on the worm gear, the abrasive (and sometimes corrosive) nature of the slurry will quickly wear down the worm gear and destroy the tolerances. In turn, this causes the pump to lose suction. This can lead to extensive downtime of the slurry pump, as well as expensive maintenance and spare parts.
- How does a dredge pump work?
- - Lower operating costs - Typically, submersible slurry pumps require much lower operating costs than dry mounted pumps due to higher efficiency.
- Safety
- One of the most frequently asked questions from our team of pump experts is: How do I pump slurry? With this in mind, our team of experts have provided a useful guide to pumping slurry.
- As wear is a function of speed, slurry pumps should be operated at the lowest possible speed; units typically run at 1,200 rpm or less. Often, direct coupling between the pump and a low-speed motor or other drive makes the most sense. On the other hand, many other applications favour gearboxes to meet the required speed and operating point. In services where variable flow rates are required, variable frequency drives are used to provide the necessary continuous speed variation.
- 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.

- In addition, a new level of complexity is added to an otherwise simple machine. Other parts must now be inventoried and training beyond basic spanner turning is required. When it comes to pumping rock and some of the world's most abrasive materials.
- The impeller is considered the heart of the dredge pump and is similar to a fan that expels air and creates centrifugal suction. At the suction pipe, this vacuum absorbs the slurry and transports the material through the discharge line.
- - Easy installation - Submersible pumps are relatively easy to install since the motor and worm gear are a single unit.
- When the slurry pump working, pump parts are easy to be impacted, wear, and corrosion, etc. Therefore, the liner of the slurry pump uses wear-resistant material, such as high chromium alloy, rubber. The wear-resistant materials can effectively reduce the wear parts of the pump. So most of the slurry pump is a wear-resistant slurry pump in the current market.
- Consider the impeller. Slurry pumps must have thicker vanes than water pumps to prevent wear. Due to the increased thickness, there will be fewer vanes, otherwise the passages will be too narrow and will affect the performance of the pump. The impeller should have a large enough passage so that the largest solid particles can pass through without clogging.
- 3.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 and tear caused by abrasive slurries. Slurry pumps are typically larger in size compared to low viscosity liquid pumps and often require more horsepower to operate due to their lower efficiency. Bearings and shafts must also be more robust and durable.
- >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.
