- pump Slurry is a type of pump designed to pump liquid containing solid particles. Slurry pumps vary in design and construction to accommodate different types of slurries that differ in solids concentration, solid particle size, solid particle shape, and solution composition. Slurry pumps are more powerful than liquid pumps. They have added sacrificial materials and replaceable wear parts to resist wear and tear.
Centrifugal, positive displacement and vortex pumps can be used for slurry. Centrifugal Slurry Pumps can have slotted or rubber or metal coated bearings between the support axes. Settings include horizontal, vertical, hover, and float.
Slurry is usually classified based on the concentration of solids. Slurry engineering classification is more complex and includes concentration, particle size, shape and weight in order to determine the severity of abrasion. Slurry is classified as class 1, class 2, class 3 and class 4 for engineering selection of slurry pumps.
Choosing slurry pumps is more difficult than choosing water and liquid pumps . Many factors and modifications to the duty point affect brake power and wear. Root Dynamic Centrifugal Slurry Pumps (ANSI/HI 12.1-12.6-2016) provides methods for calculating slurry pumps. The peripheral speed of the impeller is one of the main characteristics and classification of slurry pumps. The speed must be in accordance with the Slurry type classification (wear classification) to maintain a reasonable service life due to high wear of solids.
Before choosing a suitable slurry pump, engineers consider capacity, head, solids handling capacity, efficiency and power, speed and NPSH.
Slurry pumps are widely used in the transportation of abrasive solids in industries such as mining, dredging and steel. They are often designed to be suitable for heavy duty use. Depending on the extraction process, some slurries are corrosive, which presents a challenge because corrosion-resistant materials such as stainless steel are softer than high-iron steel. The most common metal alloy used to make slurry pumps is known as “high chrome”, which is basically white iron with 25% chromium added to make it less brittle. Rubber coatings are also for special applications where solid particles are small. used
Slurry pump components
Slurry pump impeller
An impeller, whether elastomer, stainless steel, or high chromium material, is the main rotating component that usually has vanes to transmit centrifugal force to the fluid.
Slurry pump cover
wear liners Separated parts of the outer casing of the casting contain and provide high operating pressure capabilities. The shape of the body is usually semi-round or concentric, which is less efficient than the spiral type.
Slurry pump shaft and bearing set
A large diameter single shaft with a short overhang minimizes deflection and vibration. Heavy duty roller bearings are housed in a removable bearing cartridge.
Slurry pump shaft sleeve
A hardened, corrosion-resistant sleeve with O-ring seals at both ends protects the shaft. The split fit allows the sleeve to be quickly removed or installed.
Slurry pump shaft seal
Output drive seal, packing seal, mechanical seal.
Slurry pump drive type
V belt drive, gear reducer drive, fluid coupling drive and frequency conversion. Drive devices
Slurry pump types
Slurry pump float
Floating slurry pumps are placed on the bottom of the tank, lagoon, pond or other water-filled environments and suck solids and liquids right into the pump itself. The material is taken at the inlet and passes through the hose connected to the discharge valve.
Slurry self-priming pump
A self-priming slurry pump operates from the ground and a hose is connected to the pump inlet valve. The self-priming pump draws the slurry to the pump and then discharges the material from there.
Flood suction of Slurry pump
A submersible slurry pump is attached to a tank or hopper and uses gravity to move the slurry and liquid from the chamber. Located at the bottom or underwater, the pump uses gravity to continuously fill the pump and then push the material out through the discharge valve.
