Drum pumps are a vital tool in various industries that are used to transfer liquids from barrels and large containers. One of the main components of these pumps is their shaft. Using durable and suitable materials to make the shaft can have a great impact on the efficiency and useful life of the pump. In this article, we will examine the shaft with Hastelloy material in a drum pump, its features, advantages and applications.
Introducing Hastelloy
What is Hastelloy?
Hastelloy is the trade name for a group of nickel-molybdenum-chromium alloys known for their extremely high resistance to corrosion and oxidation. These alloys have a special chemical composition that gives them exceptional resistance to corrosive environments. Some of the popular types of Hastelloy include Hastelloy C-276, Hastelloy B-3, and Hastelloy G-30.
Hastelloy features
1. Corrosion resistance: Due to its special composition, Hastelloy has very high resistance to corrosion in acidic and corrosive environments.
2. Heat resistance: These alloys can operate at high temperatures and prevent physical and chemical changes.
3. High mechanical strength: Hastelloy has high strength and hardness, which makes it suitable for industrial applications.
