Read MoreSites often rely on centrifugal pumps to provide slurry service. These pumps (and their associated piping systems) require special provisions that demand detailed knowledge of the properties of solids and slurries to prevent wear, corrosion, erosion and other adverse effects such as solids settling. Specifying the optimum combination of speed, geometry and material requires a proper balance of often conflicting pump priorities; this requires consideration of stable operation, maximum wear life, operational flexibility and minimum energy consumption.

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.

- Applications
- For certain types of slurry pumping conditions, positive displacement pumps may be a more suitable option than centrifugal pumps.
- Choosing Dry Slurry Pumps Versus Submersible Slurry Pumps
- target=_blank>Slurry Pump
- 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.
- >Slurry pumps are typically larger than standard pumps, with more horsepower and 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 move through a standard centrifugal pump.
- Vertical Slurry Pump
- Under ideal conditions, a dredge pump can produce fluid acceleration greater than the speed of its fastest moving component.
- 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.
- >Slurry Pump
- What is slurry?
- 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.
- Slurry pump construction materials
- 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.
- Heavy-Duty Slurry 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.
- Slurry Pump
- If you have experience pumping slurries, you know it's not an easy task. Slurries are heavy and difficult to pump. They cause excessive wear on pumps and their components and are known to clog suction and discharge lines if not moving fast enough. Most importantly, it’s a challenge to make slurry pumps last for a reasonable amount of time. But, there are a few things you can do to extend the life of your slurry pump and make pumping slurry less of a challenge.
- What is a slurry?
- 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.
- Determine the perfect combination of slow pumping (to reduce wear) and fast pumping to prevent solids from settling and clogging.
- A quench plan, as the name indicates, is designed to quench or cool the seal. It is normally used if short periods of dry running are expected. As illustrated bellow, the fluid is introduced into the area between the back of the seal faces and the close fit exit on the drive side of the pump.
- High head (i.e. the height to which the pump can move the liquid)
- >Slurry pumps are typically larger than standard pumps, with more horsepower and 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 move through a standard centrifugal pump.
- The 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.
- 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.
- These conditions include
- Critical to the engineering of the pump are heavy duty bearing frames and shafts, extra thick wall sections and easily replaceable wear parts. Total life cycle cost considerations are critical when specifying pumps for severe operating conditions, such as FGD service. High chrome pumps are ideal due to the corrosive pH of the slurry.
- 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.
- 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.
- Lifetime use
- Natural rubber is an excellent wear material when handling wet sand slurries. Its strength, resilience and cut resistance have a positive impact on the wear performance of slurry pumps.
- Non-settling slurries consist of very fine particles that do not settle to the bottom of the pipe and do not settle for very long (i.e. weeks).

- Slurry Pump VS Mud 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.
- Customised pumps
- The 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.
- 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.
- Slurry pumps are mainly used in industrials of mining, metallurgy, dredge, power, coal and other solid slurry transport.
- In harsh conditions with sand, sludge, rocks and mud, ordinary slurry pumps tend to clog, wear and fail frequently. But WA heavy duty slurry pumps are highly resistant to wear and corrosion, which means that the service life of our slurry pumps is better than other manufacturers' pumps.
- We know that the right rubber and ceramic liners work very well. They also last longer and can withstand more demanding use. They can also be replaced, thereby extending the life of the pump while reducing operating costs. You can also customise your pump with a variety of ceramic parts, including bushings, pump housings, impellers, wet ends and even seals.
