Zhongkai pump is also known as single-stage double suction centrifugal pump. Its main feature is the large flow of guaranteed medium. When the pump speed is fixed, its head and flow are related to the impeller diameter. Next, I will introduce the selection steps of Zhongkai pump to you. I hope it will help you when you buy it!
1、 List the basic data of Zhongkai pump:
Including: characteristics of medium, particle diameter, content, medium temperature and required flow and pressure pipe system data of the factor contained in the medium.
2、 Determine flow head:
1. If the minimum, normal and maximum flow have been given in the production process, the maximum flow shall be considered.
2. If only the normal flow is given in the production process, a certain margin should be considered.
For the pump with large flow and low head, the flow margin is 5%. For the pump with small flow and high head, the flow margin is 10%. For the pump with 50 ≤ ns ≤ 100, the flow margin is 5%. For the pump with poor quality and poor operation conditions, the flow margin is 10%.
3. If the basic data only gives weight flow, it should be converted into volume flow.
