Read MoreWhen the slurry pump working, pump parts are easy to be impacted, wear, and corrosion, etc. Therefore, the liner of the slurry pump uses wear-resistant material, such as high chromium alloy, rubber. The wear-resistant materials can effectively reduce the wear parts of the pump. So most of the slurry pump is a wear-resistant slurry pump in the current market.

Read MoreSlurries 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.

3.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 and tear caused by abrasive slurries. Slurry pumps are typically larger in size compared to low viscosity liquid pumps and often require more horsepower to operate due to their lower efficiency. Bearings and shafts must also be more robust and durable.

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.

- 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.
- Slurry pumps with rubber lining are the ideal pump for the mineral sand industry. They have a special rubber lining that makes them heavy duty pumps capable of withstanding high levels of abrasion.
- Larger impellers made of more material. This is to compensate for the wear caused by abrasive slurry.
- Another important target=_blank title=Part of the Slurry Pump>part of the slurry pump is its casing, which bears all the pressure. The slurry pump casing should have a large clearance between the impeller and the diversion angle to reduce wear and prevent large solid particles from getting stuck. Due to the extra space, there is more recirculation in the slurry pump casing under various operating conditions. Again, this accelerates wear compared to typical pumps.
- 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.
- 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.
- WA series target=_blank title=Heavy-Duty Slurry Pump>heavy-duty slurry pump is cantilevered, horizontal, natural rubber or hard metal lined centrifugal slurry pumps. They are designed for handling abrasive, high density slurries in the metallurgical, mining, coal, power, building material and other industry department.
- It is important that the pump you choose has components that will not wear out from abrasive slurries.
- Corrosiveness of the liquid or slurry mixture: More corrosive slurries will wear pump components faster and may dictate the choice of pump manufacturing materials.
- Abrasive.
- Fewer and thicker vanes on the impeller. This makes it easier for solids to pass through than the 5-9 vanes on a standard centrifugal pump - typically 2-5 vanes.
- 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.

- 2. All have vertical pumps and horizontal pumps and can convey slurry.
- Process speed doesn’t have anything to do with choosing slurry pump impeller, but it does have an effect on the life of slurry pump impeller. 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.
- 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.
