Good afternoon, the drain is 25, the return is 20mm, the minimum shaft is about 8*13mm. The return is set at 1800 l/h, but the lift height is 150 and it's throttled by about 10%, so 1200 was insufficient; it all depends on the quality of the pump... The sump is classic - 3 compartments, you can top up in another container. The skimmer goes in the drain compartment. I would keep the cooler in the sump, not in the display.
