The ceramic slurry pump is a type of ceramic slurry pump and can be used as an option for rubber slurry pumps, metal slurry pumps etc. The main material for ceramic slurry pumps is silicon carbide. The process varies from manufacturer to manufacturer, mainly resin bonded silicon carbide and sintered silicon carbide.
The most important feature of ceramic slurry pumps is that they are both wear and corrosion resistant, and their performance is much higher than that of alloy and rubber pumps.
Through years of repeated tests and data feedback from metal beneficiation plants, the service life of ceramic slurry pumps under the same working conditions is generally 3-6 times that of high chrome alloy pumps, and the price of silicon carbide materials is lower than that of high chrome alloy pumps. High chromium steel, duplex steel, etc., so that the ceramic slurry pump in the price of raw materials also has a great economic advantage compared with first-class alloy.
Unlike metal pumps, the wet end parts of ceramic pumps (impeller, throat sleeve, frame plate liner, worm shell) are mainly composed of silicon carbide inorganic non-metallic materials, which have excellent acid and alkali resistance and oxidation resistance.
Ceramic Slurry Pump
The wet end parts of the slurry pump will produce corresponding wear when conveying media containing solid particles. The crystal structure of silicon carbide is similar to that of diamond tetrahedra. It is a compound bonded mainly by covalent bonds. Its hardness is second only to that of diamond.
As the material is not easily deformed or corroded when heated, ceramic slurry pumps have been tested by MST and placed in liquids up to 120°C for 7 days. For general working conditions below 60°C, silicon carbide ceramics are perfectly adequate.
The impact strength of specially treated silicon carbide ceramics can be up to 80 times that of ordinary ceramics and can be used for slurry pumps with solid particles.

If you want to know more information about the best slurry pump , welcome to contact us today or request a quote.
- 4 times more resistant to abrasion than high chrome
- Resistant to almost all acids and alkalis from PH 0-12
-Resistant to the impact of large particles
- 3 to 8 times longer life than metal pumps
- Energy and cost savings > 20% to 40%
The reason depends on the construction 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.
