- 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.
- Larger impellers made of more material. This is to compensate for the wear and tear caused by abrasive slurries.
- 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.
- How to Choose a Dredging Pump or Slurry Pump
- Slurry Pump Selection
- Pumps designed to pump slurries will be heavier than pumps designed for less viscous liquids because slurries are heavy and difficult to pump.
- In dry installation, the hydraulic end and drive unit are located outside the oil sump. When using a submersible slurry pump for dry installation, the slurry pump must always have a cooling system installed. Consider the design of the water tank in order to deliver slurry to the pump. Agitators and side-mounted agitators cannot be used for this type of installation.
- Some models can generate discharge pressures up to 260 ft. (80 m).
- 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).
- The type of application will determine whether a dry or submersible pump solution should be installed; in some cases, a solution that combines a dry and submersible pump may be the best choice. This article outlines the benefits of target=_blank title=Submersible Slurry Pump>submersible slurry pump versus dry mount pumping and shares some general rules that apply to both applications. Next, the target=_blank title=Slurry Pump Manufacturer>slurry pump manufacturer will share the following content with you.
- Slurry pump design
- To reduce wear, reduce the pump discharge pressure to the lowest possible point.
- Reduced inventory
- Slurry pump seals
- The terms flushing and quench, often seem to be confused or misused when discussing seal support schemes for , slurry pumps, . As the concepts of a mechanical seal cartridge and a filled seal cartridge are slightly different, I will discuss them separately and in turn.
- 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.
- Dredge Pump Features
- Fine-grained sand can be extremely abrasive and typically wears slurry pumps quickly. Characteristics of coarse aggregates that can affect pump performance are size, shape and surface texture, as well as gradual changes in particle size, while fine materials can create excessive friction in the pipe.
- Submersible pumps offer many advantages over dry installation or even semi-submersible sump pumps. Submersible pumps are more flexible and efficient than alternatives.
- Selecting a dredge pump
- One of the most frequently asked questions from our team of pump experts is: How do I pump slurry?xa0With this in mind, our team of experts have provided a useful guide to pumping slurry.
- Traditionally, centrifugal pumps are used to pump highly abrasive slurries. Centrifugal pumps use the force generated by the rotating impeller to impinge kinetic energy into the slurry.
- how-does-a-dredge-pump-work
- 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.
- The Company Adopts Advanced Computer Aided Engineering Software
- Dredge Pump
- When pumping slurry in wet sand applications, we must evaluate the abrasive particles flowing through the piping and then assess how they affect the slurry pump. If the pump is lined with poor quality rubber, the particles will not rebound effectively and, as a result, the rubber will begin to break down. The air shavings then begin to accelerate and negatively impact the efficiency of the pump, often leading to turbulence.
- Carbon transfer
- What is slurry?
- >Vertical Slurry Pump
- Depending on your own requirements, propeller seals, mechanical seals or packing seals can be used.
- For certain types of slurry pumping conditions, positive displacement pumps may be a more suitable option than centrifugal pumps.
- 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.
- What is Heavy Duty Slurry Pump?
- >Slurry Pump
- How Slurry Pumps Differ From Standard Pumps?
- >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.
- Slurries 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.
- Underwater installation
- Applications of Rubber Lined Slurry Pumps
- 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.
- If youve ever pumped a slurry, you know it can be one of the most challenging fluids to work with. It is abrasive, viscous, sometimes corrosive, and contains a lot of solids. Theres no doubt that the slurry on the pump is hard. But the more you know about whats being pumped, the better your pump selection will be, resulting in longer mean time between failures.xa0Next, the , slurry pump supplier, will share the following content with you.
- Other manufacturers looking for differentiation, if not the end result, may choose to add a small part to their pump assembly in the description, thus allowing in-line adjustment of the wear ring in the suction side lining assembly.
- Materials of Construction
- - Easy installation - Submersible pumps are relatively easy to install since the motor and worm gear are a single unit.
- 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.
- Capacity: 5-30000m3/h, Head: 5-120m. The company can produce different materials including High Chromium White Iron, Super High Chromium Hypereutectic White Iron, Low Carbon High Chromium Alloy, Carbon Steel, Stainless Steel, Duplex Stainless Steel, Ductile Iron, Grey Iron, etc. We can also provide natural rubber, elastomer rubber parts and pumps.
- - Hydraulic efficiency is as important as the material, as efficiency is related to wear. The swept-back design of the impeller blades minimises the separation of solids from the carrying fluid, resulting in a more uniform flow. This results in a slower wear rate.
- Determine the operating parameters of the pump.
- Any type of impeller can be used in slurry applications, but closed slurry pump impellers are more common because they are high efficient and abrasion Resistance,. Open slurry pump impellers are usually used well for high concentration solids as they are less likely to clog. For example, the small fibers in paper stock which, in high densities, may have a tendency to clog the impeller. Pumping slurry can be difficult.
