Read MoreThe 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.

Read More>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.

Although the focus of slurry pumps is often on the size and percentage of solids to be pumped, in many applications corrosion resistance is also an important factor in material selection. In such cases, the material chosen must provide adequate resistance to erosion and corrosion.

- 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.
- If the exact in-pump viscosity of the product is unknown, CSI can help
- When 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.
- Any type of impeller can be used in slurry applications, but closed slurry pump impellers are more common because they are high efficient and abrasion Resistance,. Open slurry pump impellers are usually used well for high concentration solids as they are less likely to clog. For example, the small fibers in paper stock which, in high densities, may have a tendency to clog the impeller. Pumping slurry can be difficult.

- 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.

- If you have experience pumping slurries, you know it's not an easy task. Slurries are heavy and difficult to pump. They cause excessive wear on pumps and their components and are known to clog suction and discharge lines if not moving fast enough. Most importantly, it’s a challenge to make slurry pumps last for a reasonable amount of time. But, there are a few things you can do to extend the life of your slurry pump and make pumping slurry less of a challenge.
- Consideration should be given to installing mixers on guide rods in the catch basin/tank to keep solids in suspension and avoid settling in the catch basin/tank. When investing in a slurry pump, you want to pump slurry that includes solids, not just dirty water. Therefore, it is important to make sure that the pump is doing this; by using an agitator, the pump is fed with solids and pumping the slurry.
- Process speed doesn’t have anything to do with choosing slurry pump impeller, but it does have an effect on the life of slurry pump impeller. It is important to find the sweet spot that allows the slurry pump to run as slow as possible, but fast enough to keep solids from settling and clogging. If pumping too fast, the slurry can quickly erode the impeller due to its abrasive nature. This is why it is important to select a larger impeller if possible.
- To reduce wear, reduce the pump discharge pressure to the lowest possible point.

In applications ranging from processing to wastewater treatment, plants often have to handle slurries. Handling this mixture of liquids and solids can be challenging and difficult. Some of the key factors in slurry pumping are the size and nature of the solids in the liquid and the type of wear they cause. Another is the corrosiveness of the liquid or mixture.

- Firstly, analysing your duty helps us to determine whether you are using the type and size of pump best suited to your needs. Cavitation can occur due to surges; a very effective way to solve this problem is to install a choke on the pump head to increase the pressure on the casing, which then absorbs the surge, or to add a choke to the output to reduce the surge.

- 3. Both pumps and motors are designed separately.
- 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.
- How does a dredge pump work?
- Applications
- 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 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.
- Flushing is defined as a fluid which is introduced into the seal cavity on the process fluid side, close to the seal face, and is normally used to cool and lubricate the seal face.

- 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.
