Please inform us of the parameters and material properties to facilitate our selection.
The material is liquid yellow phosphorus with slight impurities. Liquid yellow phosphorus is extremely easy to spontaneously ignite and is highly toxic, and leakage may easily lead to combustion and explosion accidents. The viscosity is a bit high, generally 1.45~1.21mPa * s, the operating temperature is 60~90 degrees. Can you send a performance parameter table? Thank you.
Any general positive displacement pump will work, but it is recommended to use a screw pump or a plunger pump.
To prevent leakage, you can use canned pumps, magnetic pumps, or pneumatic diaphragm pumps. Parameter table, what parameter table do you want? You should send us the parameter table.
Specific performance parameters must be required before selection can be made
I recommend using the American BLACKMER eccentric rotor pump. Its material is 316L. The pump head has no mechanical seal and can be used in highly toxic environments.
It is recommended to use a canned pump or a magnetic drive pump.
Before choosing a pump, it is necessary to understand the properties of the medium. Yellow phosphorus, formerly known as white phosphorus, has a specific gravity of 1.82 and a melting point of 44°C. It is insoluble in water and highly soluble in carbon dioxide. It is highly toxic, has a special odor, is extremely soft, and is easy to cut with a knife. The most notable property of yellow phosphorus is that it is very easy to spontaneously ignite. It has an extremely low ignition point and can burn itself above 30°C. When burning, it shows a yellow flame with thick white smoke - phosphorus pentoxide. Yellow phosphorus is easily oxidized in the air and can smoke and catch fire if exposed to slight friction, vibration or impact. When we use a knife to cut yellow phosphorus, the friction of the knife will also cause the yellow phosphorus to burn. It is also prone to chemical reactions with sulfur, halogen, hydrogen, etc., producing toxic and flammable substances. Due to the highly toxic nature of yellow phosphorus, it is recommended to choose a pump without seals and zero leakage. For example, sealless self-control self-priming pumps, magnetic pumps, and pneumatic diaphragm pumps.
