Read MoreIf 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.

Read MoreA dredge pump contains a pump casing and an impeller. The impeller is mounted in the pump casing and connected to the drive motor via a gearbox and shaft. The front part of the pump casing is sealed with a suction cover and connected directly to the suction pipe of the dredger. The discharge port of the dredge pump is located near the top of the dredge pump and is connected to a separate discharge line.

- 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.
- Another way of classifying the type of slurry pump installation is dry installation or wet installation. Dry installation pumps have the hydraulic end and drive located outside the liquid, whereas wet installation pumps (such as submersible pumps) operate within a catch basin or slurry. Submersible pumps do not require much support structure and therefore do not take up much space. Depending on the type of operation and installation required, the preferred method of pump installation is determined.
- Slurry Pump selection
- On the other hand, if the slurry is not only abrasive but also has a low pH, then a duplex stainless steel construction is preferable. This material is best suited for slurry pumps to withstand harsh materials (such as acids) while still having a high Brinell hardness.
- 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.

- Will solids size pass through the pump?
- 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.
- - 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.).
- 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.
- Slurry pump impeller, is one of the most important parts of centrifugal slurry pumps. Depending on the application, slurry pump impeller selection is crucial to slurry pump performance. Slurry applications can be especially hard on the impeller of slurry pumps because of their abrasive nature. In order slurry pumps operates efficiently and stand up to the test of time, impeller has to be selected properly for slurry pumps.
- From an operational point of view the stuffing box is different as it requires some leakage to ensure lubrication and to prevent heat build up. The mechanical seal box should be leak free.
- When the slurry pump working, pump parts are easy to be impacted, wear, and corrosion, etc. Therefore, the liner of the slurry pump uses wear-resistant material, such as high chromium alloy, rubber. The wear-resistant materials can effectively reduce the wear parts of the pump. So most of the slurry pump is a wear-resistant slurry pump in the current market.

- Magnetite mixing
- 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.

- What is Heavy Duty Slurry Pump?
- Slurry pump seals
- The FGD process begins when the limestone feed (rock) is reduced in size by crushing it in a ball mill and then mixed with water in a slurry supply tank. The slurry (approx. 90% water) is then pumped into the absorption tank. As the consistency of the limestone slurry tends to change, suction conditions can occur which can lead to cavitation and pump failure.
- Conveying medium
- 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.
- 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.
- 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.

- Despite the complexity of internal flow patterns, the overall performance of dredge pumps is predictable.
- There are several types of slurry pumps, the most common being: centrifugal and volumetric pumps.
- With 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.
- >Slurry Pump
- In a word, the wear-resistant properties of the slurry pumps are stronger, and the ability to convey particles is also stronger. Generally, the capacity of the slurry pump is larger than the mud pump, which is mainly used for coal and metal ore washing. The mud pumps are more suitable for abrasive slurry is not very strong.
- Some models can generate discharge pressures up to 260 ft. (80 m).
- For example.
- 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.
