It is important to find the sweet spot that allows the slurry pump to run as slow as possible, but fast enough to keep solids from settling and clogging. If pumping too fast, the slurry can quickly erode the impeller due to its abrasive nature. This is why it is important to select a larger impeller if possible.

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.

Is the discharge configuration suitable for abrasive slurries?

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.

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.

- Horizontal pumps are the most commonly used type of slurry pump and therefore have the advantage of being easy to install or maintain, a wide range of flow parameters to choose from and a wide range of design materials to choose from. One of the advantages of vertical pumps, however, is the relatively small amount of floor space required for installation.
- The frame plate for WAJ series pumps has interchangeable hard metal or pressure moulded elastomer liners. The impellers are made of pressure moulded elastomer liners.The shaft seals for WAJ series can be packing seal, centrifugal seal or mechanical seal.
- The same point of slurry pump and mud pump
- Low slurry flow rates
- 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.
- 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.
- 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.
- If the exact in-pump viscosity of the product is unknown, CSI can help
- Larger impellers made of more material. This is to compensate for the wear caused by abrasive slurry.
- - Hydraulic efficiency is as important as the material, as efficiency is related to wear. The swept-back design of the impeller blades minimises the separation of solids from the carrying fluid, resulting in a more uniform flow. This results in a slower wear rate.
- -When pumping abrasive slurries, it is essential to use wear-resistant components with a high chromium content. But more is not always better - above 25%, the impeller becomes brittle.
- The first major requirement for >slurry pumps is to provide adequate service life. The erosive and corrosive effects of slurries, such as the impact of high velocity flow of liquid/solid mixtures, can be really challenging. In many applications, some of the solids in the mixture are larger than the particles normally specified; therefore, the pump should be able to pass through them without causing any damage or operational problems.
- In AIER® slurry pumps, WY & WYJ sump pump are vertical centrifugal slurry pump, submerged for transfer abrasive, coarse particles and high density slurry. When working, it needs no seal water or any kind of seal. It can work well as well when suction volume is not enough.
- Types of damage to slurry pumps
- Aier Machinery has strong technical force and is specially engaged in the research of abrasion resistant materials of slurry pumps, sewage pumps and water pumps and the development of new products. The materials include high chrome white iron, duplex stainless steel, stainless steel, ductile iron, rubber, etc.
- 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.
- Choosing the right material for a slurry pump is another key process in determining the right pump for handling slurry. If the slurry is highly abrasive with neutral pH, then the best material of construction is Hi-Chrome. this metallurgy has the highest Brinell hardness and can withstand the abrasiveness of the slurry.
- - Low noise level - Operating underwater results in low noise or even silent operation.
- How does a dredge pump work?
- AIER will always strive to be your common sense slurry pump and parts supplier in a complex world!
- 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.
- 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.
- The solution is to choose a >heavy duty slurry pump and, just as importantly, to use a custom built unit with replaceable parts. At Aier Machinery, building your custom slurry pump is one of our areas of expertise. We design your slurry pump to your specifications and application.
- 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.
- Many types of pumps are used for pumping slurries.The centrifugal slurry pump uses the centrifugal force generated by a rotating impeller to impact kinetic energy to the slurry, similar to how a water-like liquid would move through a standard centrifugal pump.
- Other manufacturers looking for differentiation, if not the end result, may choose to add a small part to their pump assembly in the description, thus allowing in-line adjustment of the wear ring in the suction side lining assembly.
- Desire for higher efficiency than centrifugal pumps
- - Installation flexibility - The submersible slurry pump is available in a variety of mounting models, including portable and semi-permanent (also easy to move as it can be freely suspended from a chain or similar device without having to be bolted to the ground/floor, etc.).
- >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.
- Better safety
- Heavy-Duty Slurry Pump
- 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.
- 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.

- All products are mainly supplied to environmental protection, wastewater treatment, urban water supply and drainage, mine, metallurgy, coal, petrochemical, building material, thermal power FGD, river dredging, tailing disposal and other fields.
- Hydrostatic head - i.e. the height to which the slurry must be lifted in the piping system.
- factors-to-consider-when-choosing-a-slurry-pump
- - Keeping clean catch basins clean from solids
- 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.
- Customised solutions
- Is the discharge configuration suitable for abrasive slurries?
- 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.
- Other manufacturers looking for differentiation, if not the end result, may choose to add a small part to their pump assembly in the description, thus allowing in-line adjustment of the wear ring in the suction side lining assembly.
- In this article, we will present practical guidelines and rules for slurry centrifugal pumps. We will also discuss key operating characteristics, material selection and other considerations.
- >Slurry Pump
- Despite the complexity of internal flow patterns, the overall performance of dredge pumps is predictable.
- The slurry must be pumped from the absorber tank to the top of the spray tower where it is sprayed downwards as a fine mist to react with the upward moving flue gas. With pumping volumes typically in the range of 16,000 to 20,000 gallons of slurry per minute and heads of 65 to 110 feet, rubber lined slurry pumps are the optimal pumping solution.
- It is also important to consider the chemical compatibility of the slurry with any elastomers in the pump. Once the nature of the slurry and the components of the different types of pumps have been addressed, you can select potential candidate slurry pumps for the application.
