Good galvanized wire, plating thickness of 3- 4 mm, zinc adhesion should be less than 460 grams/m, that is, the average thickness of zinc layer is not less than 65 microns. When the thickness of plated parts is greater than 4 mm, the zinc adhesion should not be less than 610 g/m, that is, the average thickness of zinc layer should not be less than 86 microns. Standard galvanized wire coating must be uniform, galvanized layer basically uniform with copper sulfate solution test etching five times no dew iron. For standard galvanized wire coating adhesion requirements, the zinc layer of plated parts should be firmly combined with the basic metal and have enough adhesion strength, after hammer test does not fall off, not convex.

- 3. Both pumps and motors are designed separately.
- 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.
- 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.
- 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.
- 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 target=_blank title=Slurry Pump>slurry pump. Let's talk about how slurry pumps differ from standard pumps and how to narrow your choices.
- If you want to know more information about the best dredge pump, welcome to >contact us today or request a quote.
- 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.
- Choosing the right slurry pump
- >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.
- How to Succeed in Slurry Pumping?
- The terms slurry pump and dredge pump can be used interchangeably.
- Two types of slurry are found in these industries.
- The concept of the >slurry pump and mud pump is very close, many people are not quite clear. Although slurry pumps and mud pumps are impurities pump, if you fully understand the two pumps, you can differentiate them very clearly from the application and transmission medium characteristics. What is the difference between the slurry pump and mud pump? Four aspects to distinguish the slurry and mud pumps.
- The solution is to choose a >heavy duty slurry pump and, just as importantly, to use a custom built unit with replaceable parts. At Aier Machinery, building your custom slurry pump is one of our areas of expertise. We design your slurry pump to your specifications and application.
- 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.

- Selecting a dredge pump
- Step 2
- A >dredge pump is a horizontal centrifugal pump that is the heart of a dredger. It is designed to handle suspended abrasive granular materials and solids of limited size. Without a dredge pump, a stranded dredger would not be able to deliver mud.
- Slurry pumps can be used to transport mixtures of liquids and solids in many industries in a wide range of applications, such as mine drainage, dredging of sunken lagoons and pumping of drilling mud.
- We know that the right rubber and ceramic liners work very well. They also last longer and can withstand more demanding use. They can also be replaced, thereby extending the life of the pump while reducing operating costs. You can also customise your pump with a variety of ceramic parts, including bushings, pump housings, impellers, wet ends and even seals.
- Particle size, shape and hardness (impact on wear and corrosion potential of pump components)
- Quenching is defined as the introduction of a neutral fluid (usually water or steam) into the atmospheric side of the seal to prevent the formation of solids that may interfere with movement or be used for other purposes.
- 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.
- Damage to slurry pumps can range from burst seals to bearings and component housings wearing out where they join, to impellers corroding due to cavitation or severe wear and so on. However, there are solutions to these problems.
- Heavy-Duty Slurry Pump
- How much solids damage can the customer tolerate?
- The construction aggregate industry conveys all forms of slurry, from fine sand to coarse aggregates.
- 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.
- One of the most frequently asked questions from our team of pump experts is: How do I pump slurry? With this in mind, our team of experts have provided a useful guide to pumping slurry.
- Compared to standard centrifugal pumps, centrifugal pumps optimized for slurry pumping typically have the following features.
- It is critical to determine the right slurry pump size and power requirements for your application. Depending on the abrasive nature of the slurry, it is important to select a pump size that will allow it to run at a slow enough speed to extend the life of the slurry pump. The ideal RPM to run a slurry pump is between 900 and 1200 RPM. Once that speed is started to be exceeded, the life of the pump is greatly reduced because the wear points of the slurry pump are actually sandblasted.
- Submersible slurry pump pumps offer many advantages over dry and semi-dry (cantilever) mounted pumps.

- There is a better way to pump sewage, overflows and other collected dirty water around the plant.
- Rubber is lighter and softer than other wear lining materials. This aids installation because it is easier to lift and install quickly and efficiently. Positive results for the health and safety of workers in the field.
- Consider the pump components
- Selecting a dredge pump
- The rule of thumb for setting the water pressure is the same when using the pack box, whether flushing. Mud pump shut-off pressure plus 10% or plus 20 psi, whichever is greater. However, the flow rate is set differently.
- 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.
- A slurry pump is a mechanical device used for the pressure-driven transfer of a fluid mixture (aka slurry). The fluid mixture consists largely of water as a liquid and solids as minerals, sand, gravel, human excrement, drilling mud or mostly crushed material.
- 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.
- Aier Machinery 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.
- reduce the discharge pressure of the pump to the lowest possible point, and.
- 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.
- 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.
