Table top fountain pump
Table top fountain pump
(OP)
Hello,
I want to make small pump for my table top fountain. Typical spec. are Q= 100 gph and H= 3 ft .
I have three question about it :
1. what is the shape for impeller?
2.What is the method for sealing? (Instead of mechanical seal )
3. It must be sealed , because works under the water .
What is the method for sealing ?
Thanks

RE: Table top fountain pump
Then I calculated Ns= N(cfm^.5)/H^.75 = .1669N.
We would like Ns to be between 500 and 800 for best efficiency. Try 500 = .1669N, then N is 2996 rpm. Say 3000 rpm. This rpm should be available in small induction or shaded pole motors.
Detail design of the pump and motor selection is a bit beyond the time and effort I am willing to spend on a freebie project... Let me know if you want to go farther.
For sealing, consider a magnetic coupling. Zero leakage!
Does this help?
