As the name suggests, the Slurry Pumps are for pumping materials. The key to slurry pump success is the generation of centrifugal force, which pushes material outward from the pump center.
Heavy Duty Slurry Pumps can withstand extensive wear due to characteristics such as a large impeller diameter, shafts, bearings, and internal passageways as well as heavy-duty construction. On an industrial level, slurry pump features generate higher upfront and operational costs compared to water pumps. However, only slurry pumps can hydro transport solid materials efficiently, and the long-term benefits outweigh the initial costs.


According to different usage scenarios, the slurry pump can be divided into three types:
Wet — In this installation, the slurry pump and drive are fully submersible. This is necessary for certain slurry pump applications, such as underwater operations.
Dry — In this installation, the pump drive and bearings are kept out of the slurry. The wet end — which includes the shell, impeller, hub or suction liner, and shaft sleeve or stuffing box — is free-standing and clear of any surrounding liquid. Slurry pump technicians install most horizontal pumps this way.
Semi-dry — This special arrangement is used for dredging applications with horizontal pumps. Operators flood the wet end and bearings but keep the drive dry. Bearings require special sealing arrangements in this case.
For more information about the slurry pump, you can contact the Slurry Pump Supplier from China (CNSME®).

This situation is generally due to the slurry pump suction pipe, or the instrument appears the phenomenon of air leakage, or may be due to the bottom of the slurry pump valve, not open the reason caused by. When encountering this kind of failure, the technical personnel should first check where the leakage position is, and give plugging in time. Secondly, the bottom valve of the slurry pump is repaired and replaced.

Slurry pump impeller material selection needs to be based on specific conditions and media characteristics to decide, common materials and selection points are as follows:
1. high chromium cast iron (Cr15, Cr27)
Features: high hardness, good wear resistance, suitable for conveying strong abrasive slurry.
Application: commonly used in mining, metallurgy and other fields of slurry transportation.
2. Rubber
Features: good elasticity, corrosion resistance, suitable for conveying corrosive media containing particles.
Application: chemical industry, environmental protection and other fields, especially suitable for more corrosive conditions.
3. polyurethane
Features: excellent abrasion resistance and elasticity, suitable for conveying slurry containing fine particles.
Application: suitable for smaller particles, less abrasive working conditions.
4. stainless steel (such as 304, 316)
Characteristics: strong corrosion resistance, suitable for conveying corrosive media.
Application: chemical, food and other industries, especially the more corrosive occasions.
5. Duplex stainless steel
Features: both high strength and corrosion resistance, suitable for high corrosion, high wear conditions.
Applications: seawater treatment, chemical and other highly corrosive areas.
6. ceramic
Features: high hardness, excellent wear resistance and corrosion resistance, but brittle.
Application: suitable for highly abrasive and corrosive working conditions.
Selection points:
Media characteristics: according to the abrasive slurry, corrosive and particle size to choose the right material.
Working conditions: consider the temperature, pressure, flow rate and other conditions on the material.
Economy: under the premise of meeting the performance requirements, choose the cost-effective material.
Service life: according to the working conditions, choose the material with better wear resistance and corrosion resistance to prolong the life of the impeller.
Summarize:
High chrome cast iron: suitable for highly abrasive working conditions.
Rubber / polyurethane: suitable for corrosive media.
Stainless steel / duplex stainless steel: suitable for corrosive conditions.
Ceramic: suitable for highly abrasive and corrosive conditions.
According to the specific conditions and media characteristics to choose the right impeller material, can enhance the efficiency and life of the pump.
