Introduction:
The OEM open impeller has a series of vanes attached to a central unit. This is done for the mounting on the shaft. However, this design is more sensitive to wear and tear of the blades.
An open impeller is less likely to get clogged and even if it does, it is easier to clean whereas in a closed impeller, if stringy material or solids are pumped, the impeller can clog and it becomes really difficult to clean them.
The slurry pump mainly transports slurry with particles, so it has high requirements for wear resistance. At present, there are two kinds of wear-resistant materials: high chromium alloy and wear-resistant rubber. So what's the difference between these two materials? Shijiazhuang Zhongqiang industrial pump to introduce to you.
High chromium alloy material is a kind of metal material, which contains 26% - 27% chromium content. Chromium material is a kind of metal element with relatively high hardness. Therefore, the level of chromium content directly determines the wear resistance of materials. Is the higher the chromium content, the better? This is not true. We all know that the higher the hardness, the more brittle it is, such as glass. Therefore, the high chromium alloy material used in the overflow parts of our slurry pump is the best proportion after many tests. It is the best in wear resistance and toughness.
The wear-resistant rubber material is a rubber lining material, which is composed of a metal skeleton inside and a layer of wear-resistant rubber lining outside the skeleton.
So which of these two materials is better? In fact, each has its own advantages and disadvantages.
1. The rubber lined pump is lighter in weight and lower in price than the high chromium alloy pump.
2. The rubber lining pump is suitable for conveying slurry without sharp particles. If there are sharp corners, it is easy to scratch the rubber, and the service life will be greatly reduced.
3. The rubber lined pump has better corrosion resistance than high chromium.
