The Mud pumps need to be equipped with auxiliary equipment, but slurry pumps not. They often need to use with high-pressure water pump when mud pump working. The high-pressure pump sent the water that larger than the mud pump pressure to the leakproof packing. Then protect the packing. Otherwise, it is easy to make the seal part wear. But the wear-resistant slurry pumps can complete the transportation work independently, which not need to equip other auxiliary equipment.

Read MoreWhen pumping slurry in wet sand applications, we must evaluate the abrasive particles flowing through the piping and then assess how they affect the slurry pump. If the pump is lined with poor quality rubber, the particles will not rebound effectively and, as a result, the rubber will begin to break down. The air shavings then begin to accelerate and negatively impact the efficiency of the pump, often leading to turbulence.

- 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.
- Stainless Steel, Duplex Stainless Steel, Ductile Iron, Grey Iron, etc. We can also provide natural rubber, elastomer rubber parts and pumps.
- 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.
- -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.

- 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.

>Dredge pumps are a special category of pumps used in the dredging process. Dredging is the process of transporting submerged sediments (usually sand, gravel or rock) from one area to another. Dredging takes place in the shallow waters of lakes, rivers or seas for land reclamation, dredging, flood control, new harbours or expansion of existing harbours. The various industries that use dredge pumps are therefore the construction industry, mining, the coal industry and the oil and gas industry.

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.

The size of slurry pump impeller must be considered to ensure it holds up against abrasive wear. Slurry pump impellers are generally larger in size when compared to slurry pumps for less abrasive liquids. The more “meat” the impeller has, the better it will hold up to the task of pumping harsh slurry mixtures. Just think of slurry pump impeller as a football team’s offensive line. These players are usually large and slow. Throughout the whole game they are beaten up, over and over again, but expected to withstand the abuse. You wouldn’t want small players in this position, just like you wouldn’t want a small impeller on your slurry pumps.

- One of the most frequently asked questions from our team of pump experts is: How do I pump slurry? With this in mind, our team of experts have provided a useful guide to pumping slurry.
- The selection of a dredge or >slurry pump can be a challenging process that can be simplified by understanding the main factors behind the smooth operation of a pump. In addition to providing more efficient performance, the right dredge pump requires less maintenance, lower power and a relatively longer life.

- Corrosiveness of the slurry
- The length of the piping. The longer the pipe, the more slurry-induced friction the pump needs to overcome.
- 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 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.

- It is also important to consider the chemical compatibility of the slurry with any elastomers in the pump. Once the nature of the slurry and the components of the different types of pumps have been addressed, you can select potential candidate slurry pumps for the application.
- 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.

- 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.

- >Dredge Pump
- 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.
- Slurry pump considerations
- 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.
- Positive displacement slurry pumps with limited capacity to deliver high head are used to pump slurry through pipes with very high solids concentrations.
- Applications
- As the slurry is collected at the bottom of the tower, more rubber lined pumps are required to transfer the slurry to storage tanks, tailings ponds, waste treatment facilities or filter presses. Depending on the type of FGD process, other pump models are available for slurry discharge, pre-scrubber recovery and catch basin applications.
- Larger impellers made of more material. This is to compensate for the wear caused by abrasive slurry.
- What we mean by slurry is basically a liquid containing solid particles. When you want to pump this slurry, there are different requirements than when pumping only dirty water. 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.
- A typical pump solution for this application is to install a hard metal >slurry pump to withstand these types of conditions. Hard metal pumps need to be able to withstand the most severe abrasive slurry service and they also need to be designed to be extremely easy to maintain and safe.
- 3. Both pumps and motors are designed separately.
- As new coal-fired power plants come on line to meet the growing demand for electricity in the US and around the world, there is an increasing need to clean plant emissions to meet clean air regulations. Special pumps help to operate these scrubbers efficiently and handle the abrasive slurries used in the flue gas desulphurisation (FGD) process.
- 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.
