The slurry is a thick, viscous, and semi-liquid mixture of a number of minerals. It is the most challenging fluid to move, made up of a high concentration of solids, very abrasive, thick, occasionally corrosive. The slurry is extremely difficult to pump, there is no doubt about that, and thus, selecting the proper pump for these abrasive applications can make a significant difference in the long-term performance of the application.
The slurry is a fluid combination made up of a water-like liquid and suspended particles. it moves with gravity but requires pumping in most cases. Examples of slurries include cement, manure, starch, and cola suspended in water. Slurries are used as a convenient way to handle solid in mining, steel, processing, and power generation.
Slurries that do not settle to the bottom of the pipe include extremely small particles and may settle over an extended period of time (i.e. weeks).
Slurries that settle are created when coarse particles aggregate in an unstable combination. Coarse particles are contained in these settling slurries.
Below Are Some Common Characteristic Of Slurries
Slurries are pumped using a variety of different types of pumps, but the most common form of pump is the centrifugal pump. Centrifugal slurry pumps work by imparting kinetic energy to the slurry via centrifugal force created by a revolving impeller, similar to how a water-like liquid would flow via a typical centrifugal pump.
The use of slurry significantly reduces the estimated life of pumping components. It is vital to pick pumps that are suited for these heavy-duty applications from the outset.
Technical Specification Of Centrifugal Slurry Pump
The impeller size/design, construction material, and discharge configurations must all be chosen carefully to avoid abrasive wear.
Slurry pumps often have open impellers, which are less prone to clogging. Closed impellers are the most prone to clogging and are the most difficult to clean.
Slurry impellers are huge. This prolongs their service life in slurry.
Slurry pumps are bigger than low-viscosity liquid pumps and require more horsepower to run due to their inefficiency. Bearings and shafts must also be tougher.
Slurry pumps are commonly coated with metal or rubber to protect the pump casing from wear. For example, Goulds Pumps’ XHD (Extra Heavy Duty) slurry pump is lined with rubber.
Metal casings are hard alloys. These casings are made to tolerate increased pressure and circulation.
The casings are chosen to suit the application. Pumps used in cement manufacturing, for example, handle small particles at low pressure. So a lightweight enclosure is appropriate. The pump casing and impeller need to be thicker and stronger to handle rocks.
It’s challenging to make the slurry pumps last for a reasonable amount of time. However, there are a few things you can do to extend the life of slurry pumps.
Here are a few things to consider before buying prolonged slurry pumps:-
Pumping slurries presents a number of difficulties, but with careful planning and the right equipment, you should be able to work worry-free for many years. Thus, it is critical to deal with a slurry pump engineer of the highest caliber.
