I want to run 12VDC 7.5 amp on-demand water pump, runs for 15 seconds a few times a day. Does anyone foresee an issue since it's not a LED?

It's a power supply. It has no idea about whether you connected an led or a stereo to it. It will work. However, you are looking to use a pump that is at the upper limits of this power supply, with a pump that in all likelihood has an inrush current of more than 7.5 amps, potentially exceeding what this supply is rated at. If I were you, I'd look for at least 125w.

This transformer should work, if you add a pmw dimmer can control the water flux.

15 Amps at 110 Volts AC is 1,650 Watts. That would be the absolute most it could handle. If your pool pump is over 1500 Watts you may be better off with a larger timer (in case of voltage spikes and sags). If your pool pump is less than 1000 Watts it should run for years (mine has).

It just ran a small fountain. Turned it on in the morning, off in the evening. I don't know the wattage on the pump, but I'm sure it's not very much. It ran well when it worked, but it should last longer than a year.

I suppose whether it is an outdoor fountain or an indoor fountain it doesn't matter. The key factor is the amps. It is capable of drawing 15 amps. Pumps typically are lower than this, so it should be just fine. I run 2 small pumps simultaneously with mine. I'd not expose this timer to water. I'd put the timer in a dry place then run the cord to the pump.

Unfortunately, no. It is a 120 volt AC device because of the internal pump motor used to pump the water is strictly an AC motor.

If these pumps are 12V, what do you need this PSU for? Just buy a suitable 12VDC power brick and be done with it. Adding this into the mix is unnecessary, assuming that you've described the intended application correctly.

The unit I have is rated at 48 watts - that means it will handle a 4 amp load at 12 vDC. If the pump/shower draws 48 watts or less, you should have no problem.

I believe if you were to use this timer for that purpose that a properly sized relay should be used to switch the load and the timer would turn the relay on and off. Pumps draw a large current especially during startup. For durability the relay should be about 30amp.

The inverter should handle the start up spike just fine and the normal pumping will not be a problem. You might end up being a bit lean on your energy production with just one solar panel, depending on your energy draw.

My system shut off after a couple months of being installed as well (240v). I removed canister and electrodes appeared to have a lot of buildup, so I made a little brass brush on a handle that I could get inside and clean the elements. after doing this several times and rinsing (water came out rust colour), I replaced and it is working fine. Will wait and see how long this one lasts. I clamped it and was only pulling about 2-3 amps initially, but after a couple days it is now up to 10-11 amps per leg.

Could be a faulty pump. I would either return the pump for replacement, or buy a new pump. They are inexpensive. I have not had any problems with mine. I would alos recommend buying an external power supply like Pyramid Model PS-4KX. I have one of these and I never have any troubles.

This pump takes 12 volts, so we got a battery holder that held 8 AA cells. I have no idea what would happen if you tried running it on a lower voltage.

I have mine on a switch, it is not an automatic on/off water activated pump.

best to run panel power through a voltage regulator then to a 12 volt battery , then from the battery to the pump.thats how I run mine with no problems.

I cannot say whether or not this leaks a tiny amount of current that could disturb or be injurious to fish. It certainly doesn't leak a lot of power or it would short out. The power supply just needs to meet the motor specs. My guess is a true aquarium pump with integrated power supply would be cheaper and safer.

The controller pictured only passes current during dark hours. You could use an additional 12VDC relay (available from Amazon) with at least a single pole double throw set of contacts to power the pump. A plain switch in between will not do it. Good luck.

Yes, I think this would work for your application. This not a float activated pump and requires at least 1/2" water to run. It's best if you have a way to turn on and off as once plugged in it will check for high water level every few minutes, if water is high it pumps until lower than 1/2" at pump.
