Help: Which brand’s potassium ammonia pumps and liquid ammonia pumps are the best? Domestic or foreign brands?
Reciprocating piston pumps produced in China by companies such as Shanghai Dalong and Shandong Shengjian are of fairly good quality, and they are widely used in the domestic market. However, domestic manufacturers basically only produce three-plunger reciprocating pumps. If a seven-plunger reciprocating pump or centrifugal pump is needed, it can only be obtained from imports.
Although the quality of domestic pumps is already very good, for a pump like yours, it’s better to choose an imported one. Due to the high speed and high pressure requirements, domestic pumps still fall short in this regard. Ask the personnel familiar with ammonia synthesis equipment; they will also recommend imported pumps to you.
