High Chrome White Iron Casting Pump Spare Parts Volute Liner

The slurry pump is primarily used for conveying slurry with particles, which makes it imperative for the pump to have high wear resistance. There are two types of wear-resistant materials currently available: high chromium alloy and wear-resistant rubber. However, what distinguishes these two materials? 
High chromium alloy is a metal material that contains 26% to 27% chromium. Chromium is a metal element that possesses relatively high hardness, and hence, the level of chromium content determines the wear resistance of the material. However, it is a common misconception that the higher the chromium content, the better the material. As we all know, the higher the hardness, the more brittle it is, as is the case with glass. Therefore, the high chromium alloy material used in the overflow parts of the slurry pump is the best proportion after numerous tests, providing the perfect balance of wear resistance and toughness.

The wear-resistant rubber material is a rubber lining material that consists of a metal skeleton inside and an outer layer of wear-resistant rubber lining.

So, which of these two materials is better? Each has its advantages and disadvantages:
1. Rubber-lined pumps are lighter in weight and less expensive than high chromium alloy pumps.
2. Rubber lining pumps are suitable for conveying slurry without sharp particles. If there are sharp corners, it is easy to scratch the rubber, which will significantly reduce the service life.
3. Rubber-lined pumps have better corrosion resistance than high chromium.

Key Components of Slurry Pumps

1. Impeller

The impeller is the heart of a slurry pump. It consists of a series of vanes that rotate and impart kinetic energy to the slurry. The impeller's design is critical for optimizing the pump's performance, including factors such as efficiency, head, and wear resistance.

2. Casing

The casing houses the impeller and directs the flow of the slurry through the pump. It is designed to withstand the erosive forces of the slurry while maintaining a high level of hydraulic efficiency. Casings can be of various types, such as volute, diffuser, or multistage, depending on the specific application requirements.

3. Shaft and Bearings

The shaft transmits the rotational energy from the motor to the impeller. It must be robust enough to withstand the torque and bending forces generated during operation. Bearings support the shaft, reducing friction and enabling smooth rotation. Proper lubrication and alignment of the shaft and bearings are essential for ensuring extended pump life and minimizing downtime.
