Does anyone know where to find small A/C powered submersible pumps, that operate at 20-25 psi? I can only find D/C pumps for ship use.I need one for running humidifiers and misters for large terrariums
AC pumps are usually rated by flow rate, not PSI, if you restrict the flow, but do not regulate the pressure of an AC pump, they will usually over heat. the first answer had a good source for the pump. you might consider a DC pump for ship use and get a 12V DC power supply for it.
My Husband purchased a 25 psi A/C water pump from Grangers Supply. Lift was no problem with it. Grangers is listed on the internet.
Gonna need more info for this one, start with the usage requirements for the equipment you are supplying. That should give you something to talk about with the local sources. The size of the terrariums and the amount of water in each one, the height that you want to lift the water is another factor to be considered. Be sure to include the diameter of tubing to be used and any special features, fountains, misters, etc. Good Luck
I okorder ... What you need is a pump that can produce 5 x15 = 75 gallons per min at whatever total dynamic head (thats static pressure + dynamic (water moving) pressure) .... do not buy the biggest pump as this will put out too much so bu one that fits your system. If your tubing runs are short and you are using plastic pipe dont worry too much about calculating the static pressure just add up the pressure of the spray nozzles...so in your case you need a pump that will run 75 gpm at 25 psi...The websites I gave you may have what are called pump curves that plot total dynamic head (pressure) against flow and some may also have efficiency on there as well choose the highest efficiency pump for your pressure and flow... Good luck...
From your question description, I'd use a condensate pump. They are about 30 bucks wholesale, so figure 50 retail. Look at one. I bet it's what you need. They are used on HVAC units. They have good head pressure for 3/4 lines. Even bigger. Your question has a lot of open spots in it. So, I'm answering the best I can. Hope this helps.
