Power source for 12v pump?
I was never very handy on electric stuff and need to learn some before, but at this time it's better to ask than sorry.
So I ordered a pump like this

for an ejector. What kind of power source should it be operated with?
Should for exaple these types of power supplies work with it, with proper wiring?

What you need is a constant voltage PSU, which is the most common type (unless its marked as constant current you can be pretty sure it's a constant
voltage type. The constant current type is primarily used to power LEDs). The ones you list should work, but I much prefer this type:

as the screw terminals simplify wiring. I would choose a unit capable of providing at least 50% more power than needed.

Although I too prefer the chassis type of power supply,
they do need wirining up safely,
so the type pointed to by Refinery is good for simplicity and safety.
If your pump is 24V 60W as in the video then you need a 24 Vdc power supply that can supply 2.5 Adc (60W/24V)
so the 3A version should be OK
BUT
I would buy the 5A version because
.it is only a little more expensive
. it would only be running at half of maxmum capacity so sould run cooler / be more reliable
. the extra current capability will ensure startup and full output flowrate or pressure from the pump.

Ah, the specific model is this one:

I thought an extra power can be handy to keep the capacity below 100%.

one of these will do
https://www.amazon.com/Mean-LRS-350-12-Switching-Power-Suppl...
you can make slight voltage adjustments +-0.5v
this one is probably overkill but get one rated for 120 wats since your device should be consuming 50% the watt rating of whatever power supply you
buy.
something more like this

The 12V 8A (96W) power supply from the original link would be more than adequate and is quite affordable.
There are so many things that operate on 12 Vdc that a high power unit such as pointed to in the post above is nice to have,
I run lots of stuff on 12Vdc and/or 12.V lead-acid batteries.
