Use an alkali horizontal centrifugal pump. If the temperature is high, the material should be nickel-copper alloy.
Use a horizontal centrifugal pump, made of 310S material.
Use horizontal corrosion-resistant chemical process pumps.
Just call Hang Jian and it will be clear as soon as you ask!
It is recommended to use Hangzhou Alkali Pump Co., Ltd., with excellent quality and moderate price.
When choosing potash-alkali transfer pumps, it is recommended to use products made by Damai or Hangzhou-based alkali pumps with acceptable quality. The material of the pump requires great attention. If the temperature is high, nickel material is used. If the conditions are not harsh, 310S can be selected.
If the temperature is not high, it is recommended to use a fluorine-lined pump, which has low maintenance costs, long service life, and low cost. The domestic nickel pump casting process is not up to standard, with serious slag addition and porosity, and high maintenance costs.
First of all, we must consider concentration, temperature, length, diameter, and economic aspects. For high temperature and high concentration, it is best to use 310S material. If economic conditions are good, it is better to use nickel pump. The pumps and valves we used were from the Xi'an Pump and Valve Factory. The leakage was not very good. There might be a problem with the casting process, but the manufacturer replaced them with new ones.
What temperature is molten potash? Suitable submersible pump materials for high temperatures: Nickel materials do not need to consider the problem that mechanical seals are easily damaged. If it is liquid potash, use a horizontal centrifugal pump sealing method: Adopt double-end mechanical seal. We can send emails to communicate with each other gxgl13707837440@263.net
