Read MoreWhen dealing with slurry, you generally want to go bigger and slower. The thicker the impeller, the better it will hold up. The slower the pump, the less erosion will inflict on the impeller. However, the impeller isn’t the only thing to worry in slurry pump when dealing with slurry. Tough, durable materials of construction are necessary most of the time. Metal slurry pump liners and wear plates are common in slurry applications.

Read MoreThe size of slurry pump impeller must be considered to ensure it holds up against abrasive wear. Slurry pump impellers are generally larger in size when compared to slurry pumps for less abrasive liquids. The more “meat” the impeller has, the better it will hold up to the task of pumping harsh slurry mixtures. Just think of slurry pump impeller as a football team’s offensive line. These players are usually large and slow. Throughout the whole game they are beaten up, over and over again, but expected to withstand the abuse. You wouldn’t want small players in this position, just like you wouldn’t want a small impeller on your slurry pumps.

- Slurry Pump
- 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.
- Mixers can also help agitators when pumping very dense particles. In applications where the tank is small and/or where pumping is desired to lower the water level in the tank, a slurry pump with an internal cooling system should be considered to avoid overheating of the stator (when the water level gets low). When pumping sediment from a dam or lagoon, consider the use of a raft unit, which is a submersible device. Agitators are recommended, as well as one or more mixers that can be mounted on the raft or pump to resuspend particles for successful pumping of particles.
- The slurry weight or consistency determines the type, design and capacity of the slurry pump required. If you have any questions about the best pump for your application, welcome to >contact us today or request a quote.
- Horizontal centrifugal pumps are commonly used for slurry service, but vertical and other types of pumps are better suited to certain specific applications. Centrifugal pumps for handling slurries have features tailored to specific services that reflect the corrosive or abrasive nature of the slurry and the concentration of solids. These may include the choice of materials, the use of liners or even different drive sizes.
- Examples of these dubious enhancements to impeller adjustment abound in the industry. One of these is the adjustable wear ring or suction liner to maintain the recommended clearance between the impeller front shroud and the throat bushing face. Almost all >slurry pumps, including AIER® slurry pumps, have features to ensure that this equipment specification can be maintained over time.

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.

- Slurry pump design
- Slurry pumps can be used to transport mixtures of liquids and solids in many industries in a wide range of applications, such as mine drainage, dredging of sunken lagoons and pumping of drilling mud.
- It is critical to determine the right slurry pump size and power requirements for your application. Depending on the abrasive nature of the slurry, it is important to select a pump size that will allow it to run at a slow enough speed to extend the life of the slurry pump. The ideal RPM to run a slurry pump is between 900 and 1200 RPM. Once that speed is started to be exceeded, the life of the pump is greatly reduced because the wear points of the slurry pump are actually sandblasted.

- Slurry Pump Considerations
- >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.
- 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 terms slurry pump and dredge pump can be used interchangeably.
- 2. All have vertical pumps and horizontal pumps and can convey slurry.
- Corrosiveness of the slurry
- A slurry is a mixture of fluids, which consists of a water-like liquid and particles. Typically, slurry acts in the same way as a viscous, sticky fluid - moving with gravity - but usually needs to be pumped.
- Submersible slurry pump pumps offer many advantages over dry and semi-dry (cantilever) mounted pumps.
- Packing the box seal
- It is often used if a short period of dry running is expected. Fluid is introduced into the area between the back of the seal face and the tight-fitting outlet on the drive side of the slurry pump.
- 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.
- With the standard flush schedule, the flow is usually adjusted by compressing the packings until a few drops of water are observed leaking from the seals on the drive side. In a quench schedule the flow rate is set by adjusting the inlet valve, while a valve is used on the exhaust side to maintain the correct seal tank pressure. If the outlet water from the seal box is too hot, the flow rate is increased until the outlet water cools, while still maintaining the correct seal box pressure.
- 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.
- Slurry Pump
- Heavy-Duty Slurry Pump
- Why would maintenance personnel want to adjust a high-speed rotating impeller to a static lining component while the unit is running? Even if interlocking devices are used to prevent static and non-static components from coming into contact, how credible are these features and what are the implications for pump wear parts, bearings and motors if these two components come into contact?
- As new coal-fired power plants come on line to meet the growing demand for electricity in the US and around the world, there is an increasing need to clean plant emissions to meet clean air regulations. Special pumps help to operate these scrubbers efficiently and handle the abrasive slurries used in the flue gas desulphurisation (FGD) process.
- - transport solids hydraulically
- Metal and/or rubber pump bushings are used to combat the erosion of solid particles found in the slurry. Metal slurry pump housings are usually made of carbide to resist erosion caused by increased pressure and circulation. Sometimes wear-resistant steel is used on the pump casing so that the pump can be welded if repairs are needed.
- What is a dredging pump?
- Selecting the right pump for slurries is critical to get the most bang for your buck. Basic pump components, such as the impeller size and design, material of construction, and discharge configurations must be considered to ensure the pump will hold up against the wear caused by an abrasive slurry. Slurry pumps are generally larger in size when compared to low-viscosity liquid pumps and usually require more horsepower to operate because they're less efficient. Bearings and shafts must be more rugged and rigid as well.
- 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.
- Determine the size of the pump
- The rule of thumb for setting the water pressure is the same when using the pack box, whether flushing. Mud pump shut-off pressure plus 10% or plus 20 psi, whichever is greater. However, the flow rate is set differently.
- The mud pump is the motor driving the piston move through the link mechanism. Then causes the change of the volume of the sealed chamber of the mud pump. and the pressure difference between inside and outside of the pump change. Finally, the process of absorbing water and draining water is complete.

- How to choose a slurry pump?
- 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.
- WY type pump casing is made of abrasion resistant metal, impeller material can be abrasion resistant metal or rubber. The submerged parts of WYJ are all lined with rubber, for transfer corrosive slurry.
- 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.
- Types of slurry pumps
- These mud pumps can pump not only sand, but also more mud. They are very effective in pumping all forms of mud, gravel, concrete, slurry, slush, etc.
- Corrosiveness of the slurry
- If you've ever pumped a slurry, you know it can be one of the most challenging fluids to work with. It is abrasive, viscous, sometimes corrosive, and contains a lot of solids. There's no doubt that the slurry on the pump is hard. But the more you know about what's being pumped, the better your pump selection will be, resulting in longer mean time between failures. Next, the target=_blank title=Slurry Pump Supplier>slurry pump supplier will share the following content with you.
- 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.
- >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.
- Dredge pumps are designed to transfer large quantities of fluids and solids.
- Slurry Pump
- Settling slurries are formed from coarse particles; they are formed from unstable mixtures. It is these settling slurries with coarse particles.
- Damage to slurry pumps can range from burst seals to bearings and component housings wearing out where they join, to impellers corroding due to cavitation or severe wear and so on. However, there are solutions to these problems.
- It is often used if a short period of dry running is expected. Fluid is introduced into the area between the back of the seal face and the tight-fitting outlet on the drive side of the slurry pump.
