To reduce component wear, most centrifugal slurry pumps run at fairly low speeds - typically less than 1200 rpm. Find the optimum position that allows the pump to run as slowly as possible but fast enough to prevent solids from settling out of the slurry deposit and clogging the lines.
-
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.

A slurry is a mixture of fluids, which consists of a water-like liquid and particles. Typically, slurry acts in the same way as a viscous, sticky fluid - moving with gravity - but usually needs to be pumped.
-
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.

- Customised solutions
- Determine the perfect combination of slow pumping (to reduce wear) and fast pumping to prevent solids from settling and clogging.
- 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.
- How does a dredge pump work?
- 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.
- Compared to standard centrifugal pumps, centrifugal pumps optimized for slurry pumping typically have the following features.
- Slurry Pump
- Choosing the right material for a slurry pump is another key process in determining the right pump for handling slurry. If the slurry is highly abrasive with neutral pH, then the best material of construction is Hi-Chrome. this metallurgy has the highest Brinell hardness and can withstand the abrasiveness of the slurry.
- -When pumping abrasive slurries, it is essential to use wear-resistant components with a high chromium content. But more is not always better - above 25%, the impeller becomes brittle.

- Typical Applications of slurry pump
- 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.
- Under ideal conditions, a dredge pump can produce fluid acceleration greater than the speed of its fastest moving component.
- The solution is to choose a >heavy duty slurry pump and, just as importantly, to use a custom built unit with replaceable parts. At Aier Machinery, building your custom slurry pump is one of our areas of expertise. We design your slurry pump to your specifications and application.
- Slurry Pump
- 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.
- Typical Applications of slurry pump
- For certain types of slurry pumping conditions, positive displacement pumps may be a more suitable option than centrifugal pumps.
- factors-to-consider-when-choosing-a-slurry-pump
- 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.
- 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.

- 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.
- 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.

- Some quench seals are planned to replace the tight fitting outlet restriction with a secondary seal and a top outlet that can be piped to capture the used quench fluid and drain it from the rotating assembly. However the principle is the same, we try to cool the seal rather than flush it in any way.
- Determine the operating parameters of the pump.
- Pumping slurry can be a challenging problem, but with the right instruction, pumping and maintenance plan, you will achieve operational success.
- Determine the nature of the material to be pumped
- Traditionally, centrifugal pumps are used to pump highly abrasive slurries. Centrifugal pumps use the force generated by the rotating impeller to impinge kinetic energy into the slurry.
- Slurry Pump Selection

A waste water pump cannot handle the solid particles of a slurry. This is where slurry pumps come in handy. >Slurry pumps are heavy duty and robust versions of centrifugal pumps, capable of handling tough and abrasive tasks.
- Applications of Rubber Lined Slurry Pumps
- Centrifugal slurry pumps capable of providing high capacity with a limited head are mainly used for pumping slurry through pipes with a concentration of less than 70% by weight of solids. Centrifugal slurry pumps can be vertical, horizontal or submersible.
- Monitoring
- 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.
- Slurry Pump Speed
- The most important thing here is to determine the pump power required to deliver a specific fluid flow at the desired or required differential pressure. Consider the following.
- Corrosiveness of the liquid or slurry mixture: More corrosive slurries will wear pump components faster and may dictate the choice of pump manufacturing materials.
- What is the pump constructed of?
- >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.
- 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.
