- - 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.
- 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.
- As this limestone slurry needs to be moved efficiently through a complex industrial process, the selection of the right pumps and valves (taking into account their whole life cycle costs and maintenance) is crucial.
- A 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.

- 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.
- For pumping abrasive slurries, these types of pumps can also be made from specialised high-wear alloys. Hardened stainless steel is also a common choice for abrasive slurries.
- Slurry Pump Impeller
- Keep in mind that slurry pumps are designed to adapt to specific pumping conditions. Pumps used in the cement industry handle most fine particles at low pressures, so the casing can be of lightweight construction. In rock pumping, the casing and impeller must be able to resist slamming, so they must be built thick and strong.

- Will solids size pass through the pump?
- >Dredge Pump
- 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.
- Slurry pump construction materials
- Natural rubber is an excellent wear material when handling wet sand slurries. Its strength, resilience and cut resistance have a positive impact on the wear performance of slurry pumps.
- - Keeping clean catch basins clean from solids

- Pumping slurry can be a challenging problem, but with the right instruction, pumping and maintenance plan, you will achieve operational success.
- The slurry must be pumped from the absorber tank to the top of the spray tower where it is sprayed downwards as a fine mist to react with the upward moving flue gas. With pumping volumes typically in the range of 16,000 to 20,000 gallons of slurry per minute and heads of 65 to 110 feet, rubber lined slurry pumps are the optimal pumping solution.
- Discharge ports can be placed at 45 degree intervals and oriented in up to 8 different positions depending on your needs.

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.
- 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.
- >Slurry pumps are typically larger than standard pumps, with more horsepower and stronger bearings and shafts. The most common type of slurry pump is the centrifugal pump. These pumps use a rotating impeller to move the slurry, similar to the way aqueous liquids move through a standard centrifugal pump.
- 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.
- Submersible pumps offer many advantages over dry installation or even semi-submersible sump pumps. Submersible pumps are more flexible and efficient than alternatives.

- WY type pump casing is made of abrasion resistant metal, impeller material can be abrasion resistant metal or rubber. The submerged parts of WYJ are all lined with rubber, for transfer corrosive slurry.
- Pumps with replaceable parts and components can have an unlimited service life. A high quality customised slurry pump with replaceable parts can last you a lifetime and should therefore be considered as a very reliable long-term investment.
- 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.

- It is critical to determine the right slurry pump size and power requirements for your application.

- A clear clean fluid supplied from an external source is normally used which is delivered to the main sealing surface on the fluid side of the sealing process. By using a closed gap throat bushing, the stuffing box can be back-pressurised to a higher pressure, ensuring that the flushing fluid does not flash across the seal face.
- The concentration of solids in the slurry - measured as a percentage of the total volume.
- 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.
- 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.
- Non-settling slurries consist of very fine particles that do not settle to the bottom of the pipe and do not settle for very long (i.e. weeks).
- As this limestone slurry needs to be moved efficiently through a complex industrial process, the selection of the right pumps and valves (taking into account their whole life cycle costs and maintenance) is crucial.
- Sites often rely on centrifugal pumps to provide slurry service. These pumps (and their associated piping systems) require special provisions that demand detailed knowledge of the properties of solids and slurries to prevent wear, corrosion, erosion and other adverse effects such as solids settling. Specifying the optimum combination of speed, geometry and material requires a proper balance of often conflicting pump priorities; this requires consideration of stable operation, maximum wear life, operational flexibility and minimum energy consumption.
- Improved flow control
- Safety
- What style of pump is suitable?
- 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.

- Selecting a dredge pump
- What is a dredging pump?
- 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
- 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.
