Slurry pump
Encyclopedia
A Slurry pump is a type of centrifugal pump
in physics
principle that increases the pressure of liquid and solid particle mixture (aka slurry
), through centrifugal force
(a rotating impeller) and converts electrical energy into slurry potential
and kinetic energy

and high concentration slurry in many industries such as:
Gold, Silver, iron ore, Lead&Zinc, Mineral sands, Tin, Steel, Titanium, Molybdenum, Copper, Electric Utilities, Oil Shale, Water&Sewage Utilities, Building areas, Coal, Sand&Gravel, Tobacco, Agriculture (hog, poultry, dairy manure), etc.

material, is the main rotating component which normally has vanes to impart the centrifugal force to the liquid.
Casing: Split outer casing halves of cast contain the wear liners and provide high operation pressure capabilities. The casing shape is generally of semi-volute or concentric, efficiencies of which are less than that of the volute
type.
Shaft and Bearing Assembly: A large diameter shaft with a short overhang minimizes deflection and vibration. Heavy-duty roller bearing are housed in a removable bearing cartridge.
Shaft sleeve: A hardened, heavy-duty corrosion-resistant sleeve with O-ring
seals at both ends protects the shaft. A split fit allows the sleeve removed or installed quickly.
Shaft Seal: Expeller drive seal, Packing seal, Mechanical seal
Drive Type: V-belt drive, gear reducer drive, fluid coupling
drive, and frequency conversion

Determine the above parameters before selecting appropriate slurry pump.
Centrifugal pump
A centrifugal pump is a rotodynamic pump that uses a rotating impeller to create flow by the addition of energy to a fluid. Centrifugal pumps are commonly used to move liquids through piping...

Physics
Physics is a natural science that involves the study of matter and its motion through spacetime, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.Physics is one of the oldest academic...

A slurry is, in general, a thick suspension of solids in a liquid.-Examples of slurries:Examples of slurries include:* Lahars* A mixture of water and cement to form concrete* A mixture of water, gelling agent, and oxidizers used as an explosive...
), through centrifugal force
Centrifugal force
Centrifugal force can generally be any force directed outward relative to some origin. More particularly, in classical mechanics, the centrifugal force is an outward force which arises when describing the motion of objects in a rotating reference frame...

Potential energy
In physics, potential energy is the energy stored in a body or in a system due to its position in a force field or due to its configuration. The SI unit of measure for energy and work is the Joule...
and kinetic energy
Kinetic energy
The kinetic energy of an object is the energy which it possesses due to its motion.It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes...

Slurry pump applications
Slurry pump are widely used to transport corrosiveCorrosive
A corrosive substance is one that will destroy or irreversibly damage another surface or substance with which it comes into contact. The main hazards to people include damage to the eyes, the skin, and the tissue under the skin; inhalation or ingestion of a corrosive substance can damage the...

Components of a slurry pump
Impeller: The impeller, either elastomerElastomer
An elastomer is a polymer with the property of viscoelasticity , generally having notably low Young's modulus and high yield strain compared with other materials. The term, which is derived from elastic polymer, is often used interchangeably with the term rubber, although the latter is preferred...

Chromium
Chromium is a chemical element which has the symbol Cr and atomic number 24. It is the first element in Group 6. It is a steely-gray, lustrous, hard metal that takes a high polish and has a high melting point. It is also odorless, tasteless, and malleable...

Volute (pump)
The volute of a centrifugal pump is the casing that receives the fluid being pumped by the impeller, slowing down the fluid's rate of flow. A volute is a curved funnel that increases in area as it approaches the discharge port. The volute converts kinetic energy into pressure by reducing speed...

Shaft sleeve: A hardened, heavy-duty corrosion-resistant sleeve with O-ring
O-ring
An O-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a disc-shaped cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.The O-ring...
