Duty Cycle: 50 hours / week during our 8 month spring / summer into autumn and about 10 hours / week in the winter, over 1700 hours / year, for over 3 [three] years
Pump Used: 360 GPH model 24 12 volt
Power Supply: Battery is charged from a 12 volt solar panel
Safety: 2.5A fuse and a 12V relay that drops out if the voltage goes below 10.8V
Maintenance: Keep the battery topped up

I built a large 4,000 gallons garden pond 4 years ago, installed a 12v solar panel to keep the pond battery charged and thus to drive a submersible pump for aeration. Started off with a cheap pump that blew up in a couple of months.
Having been a boaty in a past life and always used Rule bilge pumps without any failures decided to try one in the pond.
Your 360 GPH model 24 pump has been working for approx 50 hours / week during our 8 month spring / summer into autumn and about 10 hours / week in the winter, over 1700 hours / year, for over 3 [three] years and is still as good as the day I installed it.
The pump is 360 GPH models 24. It is pumping through a 1/2” plastic hose connected to a length of 1/2” copper pipe that passes through the basalt rock.
The battery is charged from a solar panel on the veranda roof. Connections to the pump were installed [15amp cable] underground before the lawn and path were laid. The pump is fed through a 2.5A fuse and a 12V relay that drops out if the voltage goes below 10.8V
The battery box sits in an unobtrusive corner of the veranda.
Two shots of the pump working showing just how efficient it is. A larger pump would produce too high a fountain leading to water loss in high wind. The 360 GPH was a lucky guess on my part.
The only maintenance I carry out is to keep the battery topped up. The pump just keeps on keeping on.
