The main objective of all flush water programmes is to prevent contamination of the seals by pumped water.The flush water programme for boxes is therefore very similar to the flush water programme for mechanically sealed boxes. However there are still some obvious mechanical differences. The most notable difference is the addition of a seal (packing) between the inlet and outlet limits. This minimises the amount of flushing fluid consumed.
A slurry is any mixture of a fluid (such as water) and a powdery solid. Slurries are used as a convenient way to handle bulk solids in the mining, steel processing, foundry, power generation and, more recently, frac sand mining industries. Slurries typically behave like viscous viscous fluids, flowing under gravity, but can also be pumped as needed.
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.

Slurry Pump
Quenching is defined as the introduction of a neutral fluid (usually water or steam) into the atmospheric side of the seal to prevent the formation of solids that may interfere with movement or be used for other purposes.
When flushing is required, the >slurry pump supplier recommends the API Option 32 sealed pipe arrangement as it is more suitable for services containing solids or contaminants that could damage the seal faces if recirculated in the flushing medium.
>Slurry pumps are typically larger than standard pumps, with more horsepower and stronger bearings and shafts. The most common type of slurry pump is the centrifugal pump. These pumps use a rotating impeller to move the slurry, similar to the way aqueous liquids move through a standard centrifugal pump.
In this article, we will present practical guidelines and rules for slurry centrifugal pumps. We will also discuss key operating characteristics, material selection and other considerations.
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.
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.

reduce the discharge pressure of the pump to the lowest possible point, and.
Light-duty Slurry Pump
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.
It is often used if a short period of dry running is expected. Fluid is introduced into the area between the back of the seal face and the tight-fitting outlet on the drive side of the slurry pump.
Choosing the right , slurry pump, for your application can be a daunting task. Slurry pumps can be found in almost all industries and play a vital role in many processes.The 4 key aspects to look for when determining the right slurry pump are slurry pump design, pump materials of construction, slurry pump seals, and proper slurry pump power sizing.Next, the , slurry pump supplier, will share them with you.+
How does a dredge pump work?
With the development of the dredging market, the requirements for dredging equipment are getting higher and higher, and the suction resistance and vacuum of dredging pumps are getting higher and higher, which has a great impact on the efficiency of dredging pumps and the chance of cavitation is getting higher and higher. The number of >dredging pumps is also increasing.

Under ideal conditions, a dredge pump can produce fluid acceleration greater than the speed of its fastest moving component.
Slurry pumps are mainly used in industrials of mining, metallurgy, dredge, power, coal and other solid slurry transport.
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.
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.
The rule of thumb for setting the water pressure is the same when using the pack box, whether flushing. Mud pump shut-off pressure plus 10% or plus 20 psi, whichever is greater. However, the flow rate is set differently.
High head (i.e. the height to which the pump can move the liquid)
-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.
Natural rubber is an excellent wear material when handling wet sand slurries. Its strength, resilience and cut resistance have a positive impact on the wear performance of slurry pumps.

Hydrostatic head - i.e. the height to which the slurry must be lifted in the piping system.
Slurry Pump Impeller Type
Slurries are divided into two main categories: non-settling or settling. Non-settling slurries consist of very fine particles, giving the illusion of increased apparent viscosity. These slurries usually have low wear characteristics, but require very careful consideration when selecting the right pump, as they behave differently from ordinary liquids.

Longer maintenance intervals
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 pumpsxa0help to operate these scrubbers efficiently and handle the abrasive slurries used in the flue gas desulphurisation (FGD) process.
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.
Aier Machinery has strong technical force and is specially engaged in the research of abrasion resistant materials of slurry pumps, sewage pumps and water pumps and the development of new products. The materials include high chrome white iron, duplex stainless steel, stainless steel, ductile iron, rubber, etc.
