In a subsea installation, the slurry pump runs directly in the slurry and does not require a support structure, which means it is flexible and easy to install. If possible, the catch basin should be equipped with sloping walls to allow sediment to slide down into the area directly below the pump inlet. Agitators should be used when the liquid contains large amounts of solids and has a high particle density. Freestanding or side-mounted (submersible) mixers are an excellent choice for resuspended solids, especially if the catch basin is large or does not have sloping walls.

- A slurry is any mixture of a fluid (such as water) and a powdery solid. Slurries are used as a convenient way to handle bulk solids in the mining, steel processing, foundry, power generation and, more recently, frac sand mining industries. Slurries typically behave like viscous viscous fluids, flowing under gravity, but can also be pumped as needed.

- Larger impellers made of more material. This is to compensate for the wear and tear caused by abrasive slurries.
- Types of slurry pump installation.
- 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.
- 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.
- 2.Pumping slurries poses several challenges and problems, but with proper engineering and equipment selection you can experience many years of worry-free operation. It's important to work with a qualified engineer when selecting a slurry pump because slurries can wreak havoc on a pump if not properly selected.
- 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.
- >Slurry Pump
- The selection of a dredge or >slurry pump can be a challenging process that can be simplified by understanding the main factors behind the smooth operation of a pump. In addition to providing more efficient performance, the right dredge pump requires less maintenance, lower power and a relatively longer life.
- 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.
- 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.
- Low slurry flow rates
- 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.
- Sump drainage or washdown
- 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.
- - Smaller, more efficient tank - Because the motor is cooled by the surrounding liquid, the submersible slurry pump can be started up to 30 times per hour, resulting in a smaller, more efficient tank.
- 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.

- Slurry pumps are mainly used in industrials of mining, metallurgy, dredge, power, coal and other solid slurry transport.
- Slurry pumps are usually larger than standard pumps, have more horsepower and use stronger bearings and shafts. The most common >type of slurry pump is the centrifugal pump. These pumps use a rotating impeller to move the slurry, similar to the way aqueous liquids pass through a standard centrifugal pump.
- Materials of Construction
- Slurry pump design
- Choosing the right pump for your slurry is critical to getting the most out of it. 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 caused by abrasive slurries. Compared to low-viscosity liquid pumps, target=_blank title=Slurry Pump>slurry pumps are typically larger and often require more horsepower to operate because they are less efficient. Bearings and shafts must also be more robust and durable.

- Desire for higher efficiency than centrifugal pumps
- Under ideal conditions, a dredge pump can produce fluid acceleration greater than the speed of its fastest moving component.
- Another way of classifying the type of slurry pump installation is dry installation or wet installation. Dry installation pumps have the hydraulic end and drive located outside the liquid, whereas wet installation pumps (such as submersible pumps) operate within a catch basin or slurry. Submersible pumps do not require much support structure and therefore do not take up much space. Depending on the type of operation and installation required, the preferred method of pump installation is determined.
- 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.
- 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.
- 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.
- 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.
