However the principle is the same, we try to cool the seal rather than flush it in any way.

Read MoreA 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.

Read MoreIn a subsea installation, the slurry pump runs directly in the slurry and does not require a support structure, which means it is flexible and easy to install. If possible, the catch basin should be equipped with sloping walls to allow sediment to slide down into the area directly below the pump inlet. Agitators should be used when the liquid contains large amounts of solids and has a high particle density. Freestanding or side-mounted (submersible) mixers are an excellent choice for resuspended solids, especially if the catch basin is large or does not have sloping walls.

- Pump selection for FGD
- 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.
- - 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.

What is a slurry pump?
-
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.

- A >dredge pump is a horizontal centrifugal pump that is the heart of a dredger. It is designed to handle suspended abrasive granular materials and solids of limited size. Without a dredge pump, a stranded dredger would not be able to deliver mud.
- 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.
- Pumps designed to pump slurries will be heavier than pumps designed for less viscous liquids because slurries are heavy and difficult to pump.

- Another important target=_blank title=Part of the Slurry Pump>part of the slurry pump is its casing, which bears all the pressure. The slurry pump casing should have a large clearance between the impeller and the diversion angle to reduce wear and prevent large solid particles from getting stuck. Due to the extra space, there is more recirculation in the slurry pump casing under various operating conditions. Again, this accelerates wear compared to typical pumps.
- If pump size and type are not defined, it is worth considering the following factors when selecting a dredge pump and dredge pump: type and thickness of material to be pumped, whether diesel or electric power is required, HP (kw) of engine required, pump performance data, durability, ease of maintenance and average life expectancy under normal operating conditions. life, all important attributes in the selection process. Equally important is matching the proper pipe size and composition to maintain proper material flow without clogging the pipe and to maintain the pumping output needed to get the job done.
- 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.

- 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
- 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.
- From an operational point of view the stuffing box is different as it requires some leakage to ensure lubrication and to prevent heat build up. The mechanical seal box should be leak free.

- 1. The two types of pumps are all centrifugal pumps in the working principle. They are machines that increase the energy of solid and liquid mixtures by means of centrifugal force (the rotation of the impeller of the pump). A device that converts electrical energy into kinetic and potential energy of a medium.

- 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.
