Recommendations for pump selection

This post was last edited by FLYTOINTER on 2010-7-13 at 13:16. I need to transfer the waste liquid from the sump to a 25-cubic-meter storage tank located 20 meters away. Which is better, a submersible pump or a self-priming pump? What are their respective features? Thank you!
One more thing: I asked around, and it seems that submersible pumps are much more expensive than self-priming pumps
Please tell me about the specific medium of the waste liquid, its temperature, whether there are particles present, and whether it contains acids... Contact me at QQ540992489 or by phone at 021-56091698
First, thanks to the person on floor 3. The waste liquid is at room temperature and contains almost no particles; it is a water-based solution that is quite acidic, with a pH of around 2-3.
Submersible pumps are expensive! But there’s no space for standing; it looks good, and the sealing issue can be resolved! Self-priming pump stations have space issues and difficulty with sealing, but they are inexpensive.
It is recommended to use the FZB type fluoroplastic self-priming pump, as it offers a good cost-performance ratio! Feel free to contact me if you have any questions~
Submersible pumps are expensive and difficult to maintain; for media without particles, the fluoroplastic self-priming pump mentioned above is the most cost-effective option. If you want to avoid maintenance for 2 years, choose a sealless self-priming pump. Last edited in this post by tzpump on 2009-3-20 15:59.]
Submersible pumps are quite common; they may be expensive, but as long as they work well, that’s fine
It’s best to use a lift pump! That’s our company!
It is recommended that the poster choose a leak-free magnetic submersible pump, which offers a reasonable price, low maintenance costs, and is easy to repair；

There are also limits regarding the height of self-priming centrifugal pumps. For PH2-3 waste liquid, plastic or stainless steel materials can be used. If a self-priming centrifugal pump can be utilized, then that’s obviously the better choice, as it is easier to maintain and cheaper. That’s right; wherever a horizontal pump can be used, a vertical pump should not be used, as horizontal pumps have clear advantages in terms of cost, reliability, and ease of maintenance. ——by flytointer
The prices of self-priming pumps and submersible pumps cannot be directly compared; the key factor is the depth of your tank! For specific details, you can contact us. We can answer your questions! 021-66099165
Using fluoroplastic self-priming pumps is economical and practical
It is best to use a pneumatic diaphragm pump. Search the forum for information on the characteristics of that pump; it’s very suitable for your process conditions.
