- What is a dredging pump?
- 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 pumpsxa0help to operate these scrubbers efficiently and handle the abrasive slurries used in the flue gas desulphurisation (FGD) process.
- There are many factors that should be considered when investing in a slurry pump. For example, it is important to consider the type of slurry, as the solids content of slurries can vary from 1% to 70%. It is also important to consider the level of wear and corrosion of the material being pumped; coal and some ores can corrode parts and damage your equipment fairly quickly, often beyond repair. This wear and tear can add significantly to operating costs, and you may eventually need to purchase new equipment to continue working.
- 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.
- For example.
- 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.
- Settling slurries are formed by coarse particles, which tend to form unstable mixtures. Special attention should be paid to flow and power calculations when selecting a pump. Most slurry applications consist of coarse particles and therefore have a higher abrasion resistance.
- Slurry pumps can also simply axially adjust the clearance between the impeller and the adjacent throat casing sealing surface. This helps to maintain pump performance when internal components begin to wear.
- Discharge ports can be placed at 45 degree intervals and oriented in up to 8 different positions depending on your needs.
- 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.
- It is important that the pump you choose has components that will not wear out from 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.
- 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.
- A variety of factors must be considered to ensure a satisfactory service. Here are tips for choosing the right >pump. In applications ranging from processing to wastewater treatment, plants often have to handle slurries. Handling this mixture of liquids and solids can be challenging and difficult. Some of the key factors in slurry pumping are the size and nature of the solids in the liquid and the type of wear they cause. Another is the corrosiveness of the liquid or mixture.
- Two types of slurry are found in these industries.
- 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.
- Desire for higher efficiency than centrifugal pumps
- >Dredge Pump
- The concentration of solids in the slurry - measured as a percentage of the total volume.
- - Keeping clean catch basins clean from solids
- Determine the operating parameters of the pump.
- Aier is pumping experts and offer some useful tips to maintain your >slurry pump.
- 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.
- - Pumping media where abrasive particles are present
- Low slurry flow rates
- Submersible slurry pump pumps offer many advantages over dry and semi-dry (cantilever) mounted pumps.
- Heavy-Duty Slurry Pump
- Slurry Pump
- 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.
- Larger impellers made of more material. This is to compensate for the wear and tear caused by abrasive slurries.
- Slurry Pump
- 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
- Less downtime
- >Dredge Pump
- 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.
- Repairable - target=_blank title=Rubber Lined Slurry Pumps>Rubber lined slurry pumps can be repaired by simply replacing the bushing.
- Slurry Pump
- method and level of design reach international advanced level. The company has the first-class pump performance
- - Portable and low maintenance - There are no long or exposed mechanical shafts between the motor and worm gear, which makes the submersible pump more portable. In addition, because there are no long or exposed mechanical connections between the motor and worm gear, less maintenance is required and operating costs are significantly lower.
- 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.
- 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.
- How to choose a slurry pump?
- 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.
- 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.
- Submersible slurry pump pumps offer many advantages over dry and semi-dry (cantilever) mounted pumps.
- 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.
- 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.
- 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.
