Hot dip galvanizing is to remove oil from the workpiece, pickling, dipping, drying after dipping into the dissolved zinc solution for a certain time, can be brought out. Hot dip galvanizing is an effective way to prevent corrosion of metal. It is mainly used for metal structure facilities in various industries. It is to immerse the steel parts after rust removal into the melting zinc liquid at about 500℃, so that the surface of the steel members is attached with zinc layer, so as to play the purpose of anti-corrosion. The galvanized layer is more firm.

To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the amount of surface-active substances brought in to Z. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.

- Slurry Pump Impeller
- 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.
- 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.
- First, what is a slurry? A slurry is a semi-liquid mixture, usually consisting of fine particles. Examples of slurries can include manure, cement, starch, or coal suspended in water. There are countless other combinations that can be considered slurries. Because of the added particles and thicker consistency, special pump requirements should be considered. A standard pump may be able to handle the fluid, but not as effectively as a properly sized slurry pump.
- Choosing Dry Slurry Pumps Versus Submersible Slurry Pumps
- 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.
- - 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.
- Longer maintenance intervals
- Despite the complexity of internal flow patterns, the overall performance of dredge pumps is predictable.
- Dredge Pump
- Mixers can also help agitators when pumping very dense particles. In applications where the tank is small and/or where pumping is desired to lower the water level in the tank, a slurry pump with an internal cooling system should be considered to avoid overheating of the stator (when the water level gets low). When pumping sediment from a dam or lagoon, consider the use of a raft unit, which is a submersible device. Agitators are recommended, as well as one or more mixers that can be mounted on the raft or pump to resuspend particles for successful pumping of particles.
- 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.
- How to Choose a Dredging Pump or Slurry Pump
- Materials of Construction
- Desire for higher efficiency than centrifugal pumps
- As new coal-fired power plants come on line to meet the growing demand for electricity in the US and around the world, there is an increasing need to clean plant emissions to meet clean air regulations. Special pumps help to operate these scrubbers efficiently and handle the abrasive slurries used in the flue gas desulphurisation (FGD) process.
- Slurry Pump
- 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.
- >Dredge Pump
- - 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.
- 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.
- There is a better way to pump sewage, overflows and other collected dirty water around the plant.
- How Slurry Pumps Differ From Standard Pumps?
- Stainless Steel, Duplex Stainless Steel, Ductile Iron, Grey Iron, etc. We can also provide natural rubber, elastomer rubber parts and pumps.
- 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.
- Vertical Slurry Pumps Pump Sewage More Efficiently
- - Pumping media where abrasive particles are present
- 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.
- Includes a large number of solids or particles.
- Heavy-Duty Slurry Pump
- Slurry pumps are mainly used in industrials of mining, metallurgy, dredge, power, coal and other solid slurry transport.
- 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.
- Rubber Lined Slurry Pump
- TL FGD Pump
- Slurry Pump
- 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.
- Longer maintenance intervals
- Slurry Pump
- Firstly, analysing your duty helps us to determine whether you are using the type and size of pump best suited to your needs. Cavitation can occur due to surges; a very effective way to solve this problem is to install a choke on the pump head to increase the pressure on the casing, which then absorbs the surge, or to add a choke to the output to reduce the surge.
- Slurry Pump
- There are several types of slurry pumps, the most common being: centrifugal and volumetric pumps.
- 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.

- With the development of the dredging market, the requirements for dredging equipment are getting higher and higher, and the suction resistance and vacuum of dredging pumps are getting higher and higher, which has a great impact on the efficiency of dredging pumps and the chance of cavitation is getting higher and higher. The number of >dredging pumps is also increasing.
- - Pumping media where abrasive particles are present
- - Smaller, more efficient tank - Because the motor is cooled by the surrounding liquid, the submersible slurry pump can be started up to 30 times per hour, resulting in a smaller, more efficient tank.
- What style of pump is suitable?
- The winch dredger is usually equipped with a hull-mounted dredge pump, which has an impeller centered at or below the draft line for further production and improved suction efficiency.
- 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.
