How To Succeed in Slurry Pumping?

A variety of factors must be considered to ensure satisfactory service. Here are tips for choosing the right pump. Next, the ceramic slurry pump supplier will share the following content with you.

 

In applications ranging from processing to wastewater treatment, plants often must handle slurries. Handling this mixture of liquids and solids can be challenging and difficult. Some of the key factors in slurry pumping are the size and nature of the solids in the liquid and the type of wear they cause. Another is the corrosiveness of the liquid or mixture.

 

Sites often rely on centrifugal pumps to provide slurry service. These pumps (and their associated piping systems) require special provisions that call for detailed knowledge of solids and slurry properties to prevent wear, corrosion, erosion and other adverse effects, such as solids settling. Specifying the optimal combination of speed, geometry and material requires a proper balance of often conflicting pump priorities; this requires consideration of stable operation, maximum wear life, operational flexibility and minimum energy consumption.

Custom Pumps

Horizontal centrifugal pumps are typically used for slurry service, but vertical and other types of pumps are better suited for certain specific applications. Centrifugal pumps for handling slurries have features tailored to specific services that reflect the corrosive or abrasive nature of the slurry and the concentration of solids. These may include the choice of materials, the use of liners and even different drive sizes.

 

The first major requirement for slurry pumps is to provide adequate service life. The erosive and corrosive effects of slurries, such as the impact of high velocity flow of liquid/solid mixtures, can be really challenging. In many applications, some of the solids in the mixture are larger than the particles normally specified; therefore, the pump should be able to pass through them without causing any damage or operational problems.


Why we choose silicon carbide ceramic parts instead of metal parts in slurry pumps?

Silicon carbide ceramic slurry pump is suitable for mining, metallurgy, coal power plant, chemical industry, etc. It can withstand large particles of solids and convey heavy concentration of slurry - 60% for mineral slurry and 45% for gray slurry. It can work well in the position of ball mill pump in the mine, etc.

Advantages of silicon carbide ceramic slurry pump

- Four times more resistant to abrasion than high chrome

- Resistant to almost all acids and bases from PH 0-12

- Impact resistance to large solids

- 3~8 times longer life than metal pumps

- Energy saving and cost reduction > 20%~40%

 

Why ceramic slurry pumps are more competitive than metal pumps?

The reason depends on the structure of the silicon carbide pump, whose wet part is made of sintered silicon carbide ceramic, sintered at 1400°C in an automatic nitriding furnace.

Silicon carbide is highly resistant to corrosion and has good wear resistance. The slurry flows through the SiC parts and therefore does not corrode the pump.

 

This ceramic (SIC) slurry pump adopts horizontal and vertical axial split double pump casing structure, ceramic lining, high efficiency and high head impeller design, adopts ceramic impeller, with wide flow channel, good anti clogging performance and low NPSHr. The horizontal split bearing assembly is designed with high capacity bearing. The bearing is lubricated with oil and equipped with two sets of bearing cooling system to ensure safe and reliable operation. If you want to know about the wholesale best ceramic slurry pump price, welcome to contact us.
