- Slurry Pump Selection
- Find the best position that allows the pump to run as slowly as possible (to reduce wear) but fast enough to prevent solids from settling and clogging the piping.
- Materials of Construction
- 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.
- When slurry pump working, which is the motor drives the impeller rotation. That is the impeller on the slurry work which increases the kinetic energy of the slurry. At the same time, the slurry flows to the edge of the impeller due to inertia and is discharged from the discharge pipe at a high speed.
- Dredge Pump
- 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.
- 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.
- 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.
- 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.
- 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.
- Carbon transfer
- Pumping slurry can cause excessive wear and tear on the pump and its components as the mud can clog the suction and discharge lines.
- 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.
- >Dredge pumps are a special category of pumps used in the dredging process. Dredging is the process of transporting submerged sediments (usually sand, gravel or rock) from one area to another. Dredging takes place in the shallow waters of lakes, rivers or seas for land reclamation, dredging, flood control, new harbours or expansion of existing harbours. The various industries that use dredge pumps are therefore the construction industry, mining, the coal industry and the oil and gas industry.
- The impeller is considered the heart of the dredge pump and is similar to a fan that expels air and creates centrifugal suction. At the suction pipe, this vacuum absorbs the slurry and transports the material through the discharge line.
- As this limestone slurry needs to be moved efficiently through a complex industrial process, the selection of the right pumps and valves (taking into account their whole life cycle costs and maintenance) is crucial.
- 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.

- Pumping mud is not as easy as pumping water. Depending on the type of slurry, there are many variables in choosing the right pump for the slurry. There is no formula or set-in-stone answer as to what the best slurry pump design is. You must combine knowledge and application details to select the ideal , slurry pump, . Lets talk about how slurry pumps differ from standard pumps and how to narrow your choices.
- how-does-a-dredge-pump-work
- Pumping slurry can be a challenging problem, but with the right instruction, pumping and maintenance plan, you will achieve operational success.
- To reduce wear, reduce the pump discharge pressure to the lowest possible point.
- Slurry Pump
- 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.
- Determine the nature of the material to be pumped
- 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.
- A target=_blank title=Slurry Pump>slurry pump is a special type of pump capable of handling slurry. Unlike water pumps, slurry pumps are prone to wear and tear and are more robust and durable.
- Are the pump discharge components suitable for the slurry being pumped?
- Corrosiveness of the liquid or slurry mixture: More corrosive slurries will wear pump components faster and may dictate the choice of pump manufacturing materials.
- Keep in mind that slurry pumps are designed to adapt to specific pumping conditions. Pumps used in the cement industry handle most fine particles at low pressures, so the casing can be of lightweight construction. In rock pumping, the casing and impeller must be able to resist slamming, so they must be built thick and strong.
- Corrosiveness of the liquid or slurry mixture: More corrosive slurries will wear pump components faster and may dictate the choice of pump manufacturing materials.
- Consider the pump components
- Submersible Slurry Pump
- 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.
- Dry Installation
- Flushing is defined as a fluid which is introduced into the seal cavity on the process fluid side, close to the seal face, and is normally used to cool and lubricate the seal face.
