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.

Read MoreWith the standard flush schedule, the flow is usually adjusted by compressing the packings until a few drops of water are observed leaking from the seals on the drive side. In a quench schedule the flow rate is set by adjusting the inlet valve, while a valve is used on the exhaust side to maintain the correct seal tank pressure. If the outlet water from the seal box is too hot, the flow rate is increased until the outlet water cools, while still maintaining the correct seal box pressure.

Read MoreThe 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.

- Selecting the right pump for slurries is critical to get the most bang for your buck. Basic pump components, such as the impeller size and design, material of construction, and discharge configurations must be considered to ensure the pump will hold up against the wear caused by an abrasive slurry. Slurry pumps are generally larger in size when compared to low-viscosity liquid pumps and usually require more horsepower to operate because they're less efficient. Bearings and shafts must be more rugged and rigid as well.
- If pump size and type are not defined, it is worth considering the following factors when selecting a dredge pump and dredge pump: type and thickness of material to be pumped, whether diesel or electric power is required, HP (kw) of engine required, pump performance data, durability, ease of maintenance and average life expectancy under normal operating conditions. life, all important attributes in the selection process. Equally important is matching the proper pipe size and composition to maintain proper material flow without clogging the pipe and to maintain the pumping output needed to get the job done.
- Larger impellers made of more material. This is to compensate for the wear caused by abrasive slurry.
- 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.
- Slurry pumps are mainly used in industrials of mining, metallurgy, dredge, power, coal and other solid slurry transport.
- Horizontal pumps are the most commonly used type of slurry pump and therefore have the advantage of being easy to install or maintain, a wide range of flow parameters to choose from and a wide range of design materials to choose from. One of the advantages of vertical pumps, however, is the relatively small amount of floor space required for installation.
- Then, reduce the pump discharge pressure to the lowest possible point to further reduce wear. And follow proper piping layout and design principles to ensure consistent and uniform delivery of slurry to the pump.
- Another important target=_blank title=Part of the Slurry Pump>part of the slurry pump is its casing, which bears all the pressure. The slurry pump casing should have a large clearance between the impeller and the diversion angle to reduce wear and prevent large solid particles from getting stuck. Due to the extra space, there is more recirculation in the slurry pump casing under various operating conditions. Again, this accelerates wear compared to typical pumps.
- Slurry Pump
- Under ideal conditions, a dredge pump can produce fluid acceleration greater than the speed of its fastest moving component.
- In addition, a new level of complexity is added to an otherwise simple machine. Other parts must now be inventoried and training beyond basic spanner turning is required. When it comes to pumping rock and some of the world's most abrasive materials.
- For certain types of slurry pumping conditions, positive displacement pumps may be a more suitable option than centrifugal pumps.
- Settling slurries are formed by coarse particles, which tend to form unstable mixtures. Special attention should be paid to flow and power calculations when selecting a pump. Most slurry applications consist of coarse particles and therefore have a higher abrasion resistance.
- Slurry pump seals
- Depending on the abrasive nature of the slurry, it is important to select the ideal seal. Slurry pump seals should have a hardened surface made of silicon carbide or tungsten carbide. Vortex pumps use patented seal technology that utilizes a double mechanical seal setup and a separate seal flushing system. This allows the sealing surface to be kept cool at all times without causing the slurry to overheat the seal and crack the surface.
- Aier Machinery's team of consultants are on hand to provide you with a solution to your needs. Whether you are planning to purchase a slurry pump or need spare parts for an existing pump, we will help you determine your needs and provide advice on fine-tuning your equipment to your specific application.
- Longer maintenance intervals
- There are many factors that should be considered when investing in a slurry pump. For example, it is important to consider the type of slurry, as the solids content of slurries can vary from 1% to 70%. It is also important to consider the level of wear and corrosion of the material being pumped; coal and some ores can corrode parts and damage your equipment fairly quickly, often beyond repair. This wear and tear can add significantly to operating costs, and you may eventually need to purchase new equipment to continue working.
- Critical to the engineering of the pump are heavy duty bearing frames and shafts, extra thick wall sections and easily replaceable wear parts. Total life cycle cost considerations are critical when specifying pumps for severe operating conditions, such as FGD service. High chrome pumps are ideal due to the corrosive pH of the slurry.
- Pumping slurry can present some challenges and problems, but with proper engineering and equipment selection, you can experience years of trouble-free operation. It's important to work with a qualified engineer when selecting a slurry pump, because slurry can wreak havoc on a pump if not selected properly.
- 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.
- Slurry pumps can also simply axially adjust the clearance between the impeller and the adjacent throat casing sealing surface. This helps to maintain pump performance when internal components begin to wear.
- 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.
- 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.
- 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.
- Slurry 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.
