What type of pump is suitable for transporting 25% (W) ammonia solution?
Thread Content
The head requirement is over 40 m; the multi-stage centrifugal pumps currently in use are prone to air locking. When the ammonia concentration is too high, vaporization occurs within the pump chamber, so other suitable types of transfer pumps are needed
If the volume is small, a plunger pump can be used; if the volume is large, an submersible pump should be employed, as this may reduce the risk of air entrapment. It’s just a guess
For transporting 25% ammonia solution and overcoming the problem of gas entrapment, diaphragm pumps or magnetic drive pumps are recommended. 1. **Diaphragm pump**: This type of pump has good corrosion resistance and is suitable for handling media with certain corrosive properties, such as ammonia water. More importantly, diaphragm pumps are not prone to air lock problems caused by gases in the liquid, ensuring the normal operation of the pump. 2. **Magnetic pump**: Magnetic pumps have a compact structure, and their shaft-seal-free design helps to prevent leaks inside the pump, which is particularly advantageous for handling volatile liquids such as ammonia water. At the same time, magnetic pumps have good sealing properties, which can effectively prevent air entrapment. It is recommended to choose the most suitable pump type based on specific flow requirements, installation conditions, and budget, while ensuring that the selected pump has sufficient head and flow capacity to meet the operational conditions. If it cannot be determined, you can consult a professional pump supplier or manufacturer for more detailed technical support. .
If installation doesn’t solve the problem, use a hose pump
A hose pump is a good choice; feel free to contact me if you need one.
Using an inverse-circulation chemical process shielded pump is the best option
Magnetic pumps are supported; diaphragm pumps may experience leaks in their diaphragms after long use.
