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.

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.

- Many types of pumps are used for pumping slurries.The centrifugal slurry pump uses the centrifugal force generated by a rotating impeller to impact kinetic energy to the slurry, similar to how a water-like liquid would move through a standard centrifugal pump.
- 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.
- 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 - usually 2-5 vanes.
- 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.
- - Installation flexibility - The submersible slurry pump is available in a variety of mounting models, including portable and semi-permanent (also easy to move as it can be freely suspended from a chain or similar device without having to be bolted to the ground/floor, etc.).

Centrifugal slurry pumps capable of providing high capacity with a limited head are mainly used for pumping slurry through pipes with a concentration of less than 70% by weight of solids. Centrifugal slurry pumps can be vertical, horizontal or submersible.

Consideration should be given to installing mixers on guide rods in the catch basin/tank to keep solids in suspension and avoid settling in the catch basin/tank. When investing in a slurry pump, you want to pump slurry that includes solids, not just dirty water. Therefore, it is important to make sure that the pump is doing this; by using an agitator, the pump is fed with solids and pumping the slurry.

- To reduce component wear, most centrifugal slurry pumps run at fairly low speeds - typically less than 1200 rpm. Find the optimum position that allows the pump to run as slowly as possible but fast enough to prevent solids from settling out of the slurry deposit and clogging the lines.
- Desire for higher efficiency than centrifugal pumps
- For more information about this new and improved pump, please contact us.
- 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.
- The frame plate for WAJ series pumps has interchangeable hard metal or pressure moulded elastomer liners. The impellers are made of pressure moulded elastomer liners.The shaft seals for WAJ series can be packing seal, centrifugal seal or mechanical seal.
- Determine the size of the pump
- - Reduced space requirements - Since submersible slurry pumps operate directly in the slurry, they do not require any additional support structures.
- Compared to standard centrifugal pumps, centrifugal pumps optimised for slurry pumping usually have the following features.
- Includes a large number of solids or particles.
- Includes a large number of solids or particles.
- There are three different >types of slurry pump impellers; open, closed, and semi-open. Each has its own strengths and weaknesses, depending on the application. Some are better for solids handling, others are better for high efficiency.
- 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.
- >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.

In a field that encompasses so many specialities, long-lasting, efficient and reliable quality equipment is essential.
- The slurry must be pumped from the absorber tank to the top of the spray tower where it is sprayed downwards as a fine mist to react with the upward moving flue gas. With pumping volumes typically in the range of 16,000 to 20,000 gallons of slurry per minute and heads of 65 to 110 feet, rubber lined slurry pumps are the optimal pumping solution.

- If you have experience pumping slurry, you know it is not an easy task. Slurries are heavy and difficult to pump. They can cause excessive wear on the pump and its components, and if they don't move fast enough, they can clog the suction and discharge lines. Most importantly, it can be a challenge to keep a slurry pump in use for a reasonable period of time. However, there are steps you can take to extend the life of your slurry pump and reduce the challenges of pumping slurry.
- Adapting a pump to its precise application - be it pulp and paper, gas and oil, mining or industrial applications - will have a direct impact on its service life. That's why our bespoke pumps have the unique advantage of interchangeable components. These components include slurry valves, which can be replaced every 6 months as a preventive measure and every 12 months for regular maintenance, depending on the application.

- The basic mechanical seal flushing programme is very simple. It requires that a clear/clean fluid (usually water) is introduced into the space between the actual seal and the impeller side outlet restriction. The flushing fluid is introduced at a pressure higher than the pumping pressure, thus ensuring positive outflow/flushing of the mechanical seal and a clean operating environment.
- In this article, we will present practical guidelines and rules for slurry centrifugal pumps. We will also discuss key operating characteristics, material selection and other considerations.
- - Low noise level - Operating underwater results in low noise or even silent operation.
- 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).

- Dredge pumps are designed to transfer large quantities of fluids and solids.
- What is slurry?
- The size and nature of the solids in the liquid: The size and nature will affect the amount of physical wear on the pump and its components, and whether the solids will pass through the pump without being damaged.

- 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.
