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.
2.Pumping slurries poses several challenges and problems, but with proper engineering and equipment selection you can experience many years of worry-free operation. It's important to work with a qualified engineer when selecting a slurry pump because slurries can wreak havoc on a pump if not properly selected.
Applications
What is a slurry?
Discharge ports can be placed at 45 degree intervals and oriented in up to 8 different positions depending on your needs.
Are the pump discharge components suitable for the slurry being pumped?
Depending on your own requirements, propeller seals, mechanical seals or packing seals can be used.
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.
One problem with centrifugal pumps is that the velocity and shear forces within the pump may damage the slurry/solids. Typically, twin-screw pumps cause the least damage to solids in the slurry.
It is important that the pump you choose has components that will not wear out from abrasive slurries.

Submersible slurry pump pumps offer many advantages over dry and semi-dry (cantilever) mounted pumps.
What is slurry?
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.

Slurry pump design
In 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.

Determine the size of the pump
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.
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.

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.
>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.
The most important thing here is to determine the pump power required to deliver a specific fluid flow at the desired or required differential pressure. Consider the following.

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.

Find the best position that allows the pump to run as slowly as possible (to reduce wear) but fast enough to prevent solids from settling and clogging the piping.
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.

These mud pumps can pump not only sand, but also more mud. They are very effective in pumping all forms of mud, gravel, concrete, slurry, slush, etc.

Determine the nature of the material to be pumped
Slurry pumps are usually larger than standard pumps, have more horsepower and use 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 pass through a standard centrifugal pump.
