​Features of Ceramic Slurry Pump

Jun. 22, 2021

Silicon ceramic slurry pump is suitable for mining, metallurgy, thermal power plant, chemical industry and so on. It can withstand large solids and high concentration slurry, of which slag slurry accounts for 60% and ash slurry accounts for 45%. It can work well in places such as mining ball mill pump. Next, the ceramic slurry pump supplier will share the following content with you.


Advantages of silicon ceramic slurry pump.

- Abrasion resistance is 4 times of high chrome

- Resistant to almost all acid and alkali corrosion from PH0-12 - Resistant to large

impact of particles

- 3 to 8 times longer life than metal pumps

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


But are you curious about the reason 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.

Features of Ceramic Slurry Pump

The biggest characteristic of ceramic slurry pump is both wear-resisting and corrosion-resisting, and the performance is far higher than alloy pump and rubber pump.


Through many tests and data feedback in metal concentrating plant for many years, the service life of ceramic slurry pump is generally 3-6 times of that of High Chromium Alloy pump under the same working condition, and the price of silicon carbide material is lower than that of high chromium steel, duplex steel, and so on, so that the ceramic slurry pump in raw material prices compared with the first-class alloy also has a great economic advantage.


1. Corrosion resistance

Unlike metal pumps, ceramic pump wet end components (impeller, throat bush, frame plate liner insert, volute) are mainly composed of silicon carbide inorganic non-metallic materials, with excellent acid and alkali resistance, oxidation resistance.

2. Wear resistance

The ceramic slurry pump parts will produce corresponding wear while transferring the media contains solid particles. The crystalline structure of Silicon Carbide is similar to that of Diamond Tetrahedron. It is a compound mainly bonded by covalent bond. Its hardness is second only to diamond.


3. Heat resistance

Because the material is not easy to be deformed or corroded when it is heated, tested by MST, the ceramic slurry pump is put in the liquid with the highest temperature of 120 °C for 7 days. For the general working condition below 60 °C, Silicon Carbide ceramics can be completely satisfied.


4. Shock Resistance

The impact strength of Silicon Carbide ceramics treated by special process can reach 80 times of that of common ceramics, which can be used in slurry pump with solid granule.

Yi Jia ceramic slurry pump spare parts have long life and high efficiency. It reduces the operating cost of the slurry pump for mining customers, high efficiency can save electricity costs, long service life, and can greatly reduce the consumption of spare parts. The average cost savings for customers exceeds 30%. If you want to get more information about the best ceramic slurry pump wholesale, welcome to contact us.
