The impeller is considered the heart of the dredge pump and is similar to a fan that expels air and creates centrifugal suction. At the suction pipe, this vacuum absorbs the slurry and transports the material through the discharge line.

Read MoreA 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.

Read MoreAnother way of classifying the type of slurry pump installation is dry installation or wet installation. Dry installation pumps have the hydraulic end and drive located outside the liquid, whereas wet installation pumps (such as submersible pumps) operate within a catch basin or slurry. Submersible pumps do not require much support structure and therefore do not take up much space. Depending on the type of operation and installation required, the preferred method of pump installation is determined.

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.

Read MoreThe 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.

- 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.

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.

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.

- 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.

- Many types of pumps are used to pump slurry, but the most common slurry pump is the centrifugal pump. Centrifugal slurry pumps use centrifugal force from a rotating impeller to impinge kinetic energy on the slurry, similar to the way watery liquids pass through a standard centrifugal 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.
- Slurry pumps can also simply axially adjust the clearance between the impeller and the adjacent throat casing sealing surface. This helps to maintain pump performance when internal components begin to wear.
- 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.
- Larger impellers made of more material. This is to compensate for the wear caused by abrasive slurry.
- Compared to standard centrifugal pumps, centrifugal pumps optimized for slurry pumping typically have the following features.

- 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.
- Examples of these dubious enhancements to impeller adjustment abound in the industry. One of these is the adjustable wear ring or suction liner to maintain the recommended clearance between the impeller front shroud and the throat bushing face. Almost all >slurry pumps, including AIER® slurry pumps, have features to ensure that this equipment specification can be maintained over time.
- Pumping slurry can be a challenging problem, but with the right instruction, pumping and maintenance plan, you will achieve operational success.
- 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.
- 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.

- To reduce wear, reduce the pump discharge pressure to the lowest possible point.
- When slurry pump working, which is the motor drives the impeller rotation. That is the impeller on the slurry work which increases the kinetic energy of the slurry. At the same time, the slurry flows to the edge of the impeller due to inertia and is discharged from the discharge pipe at a high speed.

- 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.
- 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.
