- Larger impellers made of more material. This is to compensate for the wear caused by abrasive slurry.
- Again, to meet life cycle cost considerations, pumps should be equipped with large diameter impellers for lower operating speeds and longer wear life, as well as field replaceable rubber liners that can be bolted on for quick maintenance. In a typical coal-fired power plant, two to five pumps will be used in each spray tower.
- 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.
- 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.

- The design of the slurry pump is critical to ensure that the abrasive and often corrosive aspects of the slurry do not damage the impeller. In addition, slurries and sludges may contain large amounts of unforeseen solids, which will inevitably clog many types of pumps. Since most centrifugal pump impellers have very tight tolerances on the worm gear, the abrasive (and sometimes corrosive) nature of the slurry will quickly wear down the worm gear and destroy the tolerances. In turn, this causes the pump to lose suction. This can lead to extensive downtime of the slurry pump, as well as expensive maintenance and spare parts.
- Compared to standard centrifugal pumps, centrifugal pumps optimised for slurry pumping usually have the following features.
- The size and nature of the solids in the liquid: The size and nature will affect the amount of physical wear on the pump and its components, and whether the solids will pass through the pump without being damaged.
- Depending on your own requirements, propeller seals, mechanical seals or packing seals can be used.
- Longer maintenance intervals
- The construction aggregate industry conveys all forms of slurry, from fine sand to coarse aggregates.
- In a subsea installation, the slurry pump runs directly in the slurry and does not require a support structure, which means it is flexible and easy to install. If possible, the catch basin should be equipped with sloping walls to allow sediment to slide down into the area directly below the pump inlet. Agitators should be used when the liquid contains large amounts of solids and has a high particle density. Freestanding or side-mounted (submersible) mixers are an excellent choice for resuspended solids, especially if the catch basin is large or does not have sloping walls.
- 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.
- Pumps designed to pump slurries will be heavier than pumps designed for less viscous liquids because slurries are heavy and difficult to pump.
- Under ideal conditions, a dredge pump can produce fluid acceleration greater than the speed of its fastest moving component.
- Our firm 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.
- For example.
- 600WN to 1000WN dredge pumps are of double casings, single stage cantilevered centrifugal pumps. These pumps are equipped with frame and lubrication is force thin oil. The design of double casing the pump working till the volute liner almost worn down and guarantee no leakage when volute liner is worn down.
- How to choose a slurry pump?
- 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 - typically 2-5 vanes.
- The slurry pump is mainly used in the mining industry, its wear resistance is strong. So It conveys slurry that containing slag, but it can conveys mud. The mud pump is usually made of cast iron, the wear resistance of the pump is low. So the mud pumps often used for conveying mud or slurry containing suspended particles.
- Under ideal conditions, a dredge pump can produce fluid acceleration greater than the speed of its fastest moving component.
- 2. All have vertical pumps and horizontal pumps and can convey slurry.
- 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.
- It is often used if a short period of dry running is expected. Fluid is introduced into the area between the back of the seal face and the tight-fitting outlet on the drive side of the slurry pump.

- It is important that the pump you choose has components that will not wear out from abrasive slurries.

- If the exact in-pump viscosity of the product is unknown, CSI can help
- Find the best position that allows the pump to run as slowly as possible (to reduce wear) but fast enough to prevent solids from settling and clogging the piping.
- 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.

- Determine the operating parameters of the pump.
- Pump selection for FGD
- 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.
- Particle size, shape and hardness (impact on wear and corrosion potential of pump components)
- Caution: A common mistake is to over-pressurise the box and damage the expensive mechanical seal.
- A quench plan, as the name indicates, is designed to quench or cool the seal. It is normally used if short periods of dry running are expected. As illustrated bellow, the fluid is introduced into the area between the back of the seal faces and the close fit exit on the drive side of the pump.
- Larger impellers made of more material. This is to compensate for the wear caused by abrasive slurry.
- Mud pumps are mainly used for drilling, pharmaceutical, brewing, paper, and other industries, which used to transport suspension.
