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

Read MoreSelecting the right pump for slurries is critical to get the most bang for your buck. Basic pump components, such as the impeller size and design, material of construction, and discharge configurations must be considered to ensure the pump will hold up against the wear caused by an abrasive slurry. Slurry pumps are generally larger in size when compared to low-viscosity liquid pumps and usually require more horsepower to operate because they're less efficient. Bearings and shafts must be more rugged and rigid as well.

- 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.
- 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.

The FGD process begins when the limestone feed (rock) is reduced in size by crushing it in a ball mill and then mixed with water in a slurry supply tank. The slurry (approx. 90% water) is then pumped into the absorption tank. As the consistency of the limestone slurry tends to change, suction conditions can occur which can lead to cavitation and pump failure.

Settling slurries are formed by coarse particles, which tend to form unstable mixtures. Special attention should be paid to flow and power calculations when selecting a pump. Most slurry applications consist of coarse particles and therefore have a higher abrasion resistance.

Slurry Pump selection

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.

- The terms 'flushing' and 'quench' often seem to be confused or misused when discussing seal support schemes for >slurry pumps. As the concepts of a mechanical seal cartridge and a filled seal cartridge are slightly different, I will discuss them separately and in turn.
- 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 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.

- Another 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.
- 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.
- Pumping slurry can present some challenges and problems, but with proper engineering and equipment selection, you can experience years of trouble-free operation. It's important to work with a qualified engineer when selecting a slurry pump, because slurry can wreak havoc on a pump if not selected properly.

- The length of the piping. The longer the pipe, the more slurry-induced friction the pump needs to overcome.
- 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.
- A slurry is a mixture of fluids, which consists of a water-like liquid and particles. Typically, slurry acts in the same way as a viscous, sticky fluid - moving with gravity - but usually needs to be pumped.
- 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.

- 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.
- 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.
- With the standard flush schedule, the flow is usually adjusted by compressing the packings until a few drops of water are observed leaking from the seals on the drive side. In a quench schedule the flow rate is set by adjusting the inlet valve, while a valve is used on the exhaust side to maintain the correct seal tank pressure. If the outlet water from the seal box is too hot, the flow rate is increased until the outlet water cools, while still maintaining the correct seal box pressure.
- Rubber lined pumps offer many advantages
- 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.
- Some models can generate discharge pressures up to 260 ft. (80 m).
- 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.
- 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.
- Again, to meet life cycle cost considerations, pumps should be equipped with large diameter impellers for lower operating speeds and longer wear life, as well as field replaceable rubber liners that can be bolted on for quick maintenance. In a typical coal-fired power plant, two to five pumps will be used in each spray tower.
