Caustic soda solution pump
Thread Content
The existing purifier is a packed tower, using 20% caustic soda solution as the purification agent at a temperature of less than 50 degrees. What type of pump should be used? Seal material?
Using a Hangzhou alkali pump, it can be done in 310 seconds.
You can directly choose the Woman pumps produced by Shijiazhuang Water Pump Factory
Stainless steel 316 will do; we use Hangjian pumps.
Acid- and alkali-resistant pumps made of plastic alternatives can be used, offering good cost-performance; for mechanical seals, cemented carbide materials are employed
I’d like to ask gently: can a regular cast-iron pump work in this situation?
I think that if cost-effectiveness is a consideration and the requirements are not high, ordinary IS centrifugal pumps will suffice. For the mechanical seal, 108 cemented carbide will do
The temperature and concentration are not high; 304 material will suffice, and the quality from Hangzhou Alkali Pump Factory is good
How about the XL32-20-315 from Dalian Deep Blue Pump Industry Co., Ltd.?
I think it’s the same principle: the temperature isn’t high, and the concentration isn’t high either. Alkalis also have little corrosive effect on steel. The purification tower provided by the manufacturer is also made of carbon steel; a pump made of cast iron should work fine, as cast iron has better corrosion resistance than carbon steel. 7# huangyugen789
After checking the information, the available materials include: Cr13, Cr17 series, cast iron, cast steel, phenolic plastics, etc. It is recommended to use cast iron for applications with low stress, and cast steel for those with high stress. Cast iron was chosen.
