- Determine the nature of the material to be pumped
- Auxiliary equipment
- Will solids size pass through the pump?
- Selecting a dredge pump
- >Slurry pump impeller is one of the most important parts of centrifugal slurry pumps. Depending on the application, slurry pump impeller selection is crucial to slurry pump performance. Slurry applications can be especially hard on the impeller of slurry pumps because of their abrasive nature. In order slurry pumps operates efficiently and stand up to the test of time, impeller has to be selected properly for slurry pumps.
- Types of damage to slurry pumps
- 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.
- target=_blank>Slurry Pump
- The dredge pump is designed to draw sediment, debris and other hazardous materials from the surface layer into the suction pipe and transport the material through the pipe to the discharge site. The pump must be able to handle common solid debris of various sizes that can pass through the pump, thus minimizing the downtime required for cleaning.
- Typically, slurries are.
- -When pumping abrasive slurries, it is essential to use wear-resistant components with a high chromium content. But more is not always better - above 25%, the impeller becomes brittle.
- 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.
- 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.
- 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.
- 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.
- 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.
- Examples of these dubious enhancements to impeller adjustment abound in the industry. One of these is the adjustable wear ring or suction liner to maintain the recommended clearance between the impeller front shroud and the throat bushing face. Almost all >slurry pumps, including AIER® slurry pumps, have features to ensure that this equipment specification can be maintained over time.
- 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 Pump
- Two types of slurry are found in these industries.
- >Dredge Pump
- - 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.
- Working principle
- The company uses advanced computer assistant engineering software to design products and technology, which makes our
- Our firm has strong technical force and is specially engaged in the research of abrasion resistant materials of slurry pumps, sewage pumps and water pumps and the development of new products. The materials include high chrome white iron, duplex stainless steel, stainless steel, ductile iron, rubber, etc.
- 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.
- What are the materials used to construct the pump?
- Make sure you follow the basic rules of pump piping.
- Safety
- Despite the complexity of internal flow patterns, the overall performance of dredge pumps is predictable.
- 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.
- method and level of design reach international advanced level. The company has the first-class pump performance
- Abrasive.
- - Reduced space requirements - Since submersible slurry pumps operate directly in the slurry, they do not require any additional support structures.
- The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications. There are many drive modes for option, such as V-belt, flexible coupling, gearbox, hydraulic coupler variable frequency, silicon controlled speed, etc. Among them, the flexible shaft coupling drive and V-belt feature of low cost and easy installation.
- 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.
- 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.
- 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.
- On the other hand, if the slurry is not only abrasive but also has a low pH, then a duplex stainless steel construction is preferable. This material is best suited for slurry pumps to withstand harsh materials (such as acids) while still having a high Brinell hardness.
- 2. All have vertical pumps and horizontal pumps and can convey slurry.
- We use CFD, CAD method for product design and process design based absorbing experience of world leading pump companies. We integrate molding, smelting, casting, heat treatment, machining and chemical analysis, and have professional engineering and technical personnel.
- Dredge Pump Features
- Why would maintenance personnel want to adjust a high-speed rotating impeller to a static lining component while the unit is running? Even if interlocking devices are used to prevent static and non-static components from coming into contact, how credible are these features and what are the implications for pump wear parts, bearings and motors if these two components come into contact?
- Caution: A common mistake is to over-pressurise the box and damage the expensive mechanical seal.

- >Slurry Pump
- 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.
