Read MoreThe 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.

- >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.

What is Heavy Duty Slurry Pump?
-
When 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.

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.

- Traditionally, centrifugal pumps are used to pump highly abrasive slurries. Centrifugal pumps use the force generated by the rotating impeller to impinge kinetic energy into 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.
- When slurry pump working, which is the motor drives the impeller rotation. That is the impeller on the slurry work which increases the kinetic energy of the slurry. At the same time, the slurry flows to the edge of the impeller due to inertia and is discharged from the discharge pipe at a high speed.
- Slurries are divided into two main categories: non-settling or settling. Non-settling slurries consist of very fine particles, giving the illusion of increased apparent viscosity. These slurries usually have low wear characteristics, but require very careful consideration when selecting the right pump, as they behave differently from ordinary liquids.

- 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.
- Choosing the right slurry pump
- 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.
- The concept of the >slurry pump and mud pump is very close, many people are not quite clear. Although slurry pumps and mud pumps are impurities pump, if you fully understand the two pumps, you can differentiate them very clearly from the application and transmission medium characteristics. What is the difference between the slurry pump and mud pump? Four aspects to distinguish the slurry and mud pumps.
- Fine-grained sand can be extremely abrasive and typically wears slurry pumps quickly. Characteristics of coarse aggregates that can affect pump performance are size, shape and surface texture, as well as gradual changes in particle size, while fine materials can create excessive friction in the pipe.
- Quenching is defined as the introduction of a neutral fluid (usually water or steam) into the atmospheric side of the seal to prevent the formation of solids that may interfere with movement or be used for other purposes.
- If centrifugal, are the impellers of the right design and material?
- 1.Find the spot that allows the pump to run as slow as possible (to reduce wear), but fast enough to keep solids from settling and clogging the lines.To reduce wear, lower the pump’s discharge pressure to the lowest point possible. Follow proper piping principles to ensure a constant and uniform delivery of the slurry to the pump.
- Follow proper piping principles to ensure consistent and uniform delivery of mud to the pump.
- Dredge pumps are designed to transfer large quantities of fluids and solids.
- 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.

- Quenching is defined as the introduction of a neutral fluid (usually water or steam) into the atmospheric side of the seal to prevent the formation of solids that may interfere with movement or be used for other purposes.
- Some quench seals are planned to replace the tight fitting outlet restriction with a secondary seal and a top outlet that can be piped to capture the used quench fluid and drain it from the rotating assembly. However the principle is the same, we try to cool the seal rather than flush it in any way.
- 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.

- With the development of the dredging market, the requirements for dredging equipment are getting higher and higher, and the suction resistance and vacuum of dredging pumps are getting higher and higher, which has a great impact on the efficiency of dredging pumps and the chance of cavitation is getting higher and higher. The number of , dredging pumps, is also increasing.
- 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.

- As the slurry is collected at the bottom of the tower, more rubber lined pumps are required to transfer the slurry to storage tanks, tailings ponds, waste treatment facilities or filter presses. Depending on the type of FGD process, other pump models are available for slurry discharge, pre-scrubber recovery and catch basin applications.
- 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.
- If the exact in-pump viscosity of the product is unknown, CSI can help
- 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.
- The basic mechanical seal flushing programme is very simple. It requires that a clear/clean fluid (usually water) is introduced into the space between the actual seal and the impeller side outlet restriction. The flushing fluid is introduced at a pressure higher than the pumping pressure, thus ensuring positive outflow/flushing of the mechanical seal and a clean operating environment.
- 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.
