The slurry transported by the Foam Pump(KEXON) is generally the slurry with a lot of granules, so this has a very high demand for the wear resistance of the foam pump. What material is the sheath of the foam pump? What is the best service in the Shijiazhuang industrial pump factory? The Shijiazhuang pump factory with the highest quality is introduced.

The jacket of the foam pump is made of high chromium alloy. Why should we use this material to cast it? This is because the high chromium alloy is the third generation white cast iron developed from ordinary white cast iron and nickel hard cast iron. Its hardness determines its wear resistance, so it is necessary to use this material to make the jacket of foam pump.

Generally speaking, the specifications of this nickel cast iron are: high chromium white cast iron contains more than 11% chromium and the ratio of chromium to carbon is between 4 and 8. Under these conditions, M7C3 carbides with high hardness almost completely replace M3C carbides. M7C3 carbides are basically isolated hollow hexagonal. Compared with M3C carbides with continuous network distribution, M7C3 carbides greatly enhance the continuity of the matrix, thus the overall toughness of the material is significantly improved.

At present, high chromium cast iron has been recognized as an excellent wear-resistant material in the world. It has been widely used in mining, cement, electric power, road construction machinery, refractories and so on. So the foam pump jacket with high chromium cast iron can make the wear resistance of the foam pump more improved.
