Rear Protection Plate

The rear guard plate of slurry pump is one of the flow parts of slurry pump. Because the transported material contains various solid particles and acid and alkali ions, it causes serious wear and corrosion to the flow parts of slurry pump, so the rear guard plate and other flow parts of slurry pump have higher wear resistance and corrosion resistance requirements. The material of the rear protection plate of the slurry pump after the eye is generally wear-resistant alloy, rubber, ceramics, polyurethane. Among them, the alloy has high hardness and good wear resistance, but poor corrosion resistance. Ceramic hardness, wear resistance, corrosion resistance, but brittle, difficult to be used in slurry pump. Polyurethane has excellent wear resistance and corrosion resistance, and wear is fatigue wear. Rubber is a material with good conveying effect for slurry with small particle size, good wear resistance and corrosion resistance, and has good resistance to acid and alkali corrosion, and its application is constantly promoted.
