Slurry pump rear guard is one of the components of slurry pump flow parts.
Its main function is to cooperate with the sheath to form a semi-closed flow passage, so that the slag slurry can run in the space. Since the guard plate is parallel to the running direction of the slag slurry, it has a longer service period compared to the sheath and the impeller.
The material of the rear guard plate of slurry pump is usually high chromium alloy, which has good wear resistance. In addition, there is also a rubber rear guard board, but it is not suitable for materials containing sharp corner particles in the liquid. There is also an A49 material rear plate, which is generally used in desulfurization projects, and has good corrosion resistance.

 High-chromium wear-resistant cast iron KmTBCr26, High Chrome 26%  has high hardness and heat treatment hardness of HRC58~62. It has good abrasion resistance. As for alkaline mixed liquid, it has good corrosion resistance and can be used in strong abrasion conditions. The casting process of high chromium cast iron is difficult and difficult to process. However, it has a long service life and moderate price, and is the most common material used for slurry pump.
This alloy provides a great balance of hardness and toughness, making it effective to pump high abrasion and corrosive liquid. 
It provides modest corrosion resistance pump components such as the impellers, casings, volute liners and throatbushes
Material Type:  Erosion resistant white iron.
