Are you thinking of trenching around the outside of the foundation for your curtain drain tiles or are you going to cut a trench in the basement fllor? Which ever you choose you need to connect those tiles to the pit inside the basement. The pit shouldbe back filled with gravel and the cemented in. The pump sits down inside th pit and can be submersible of pedestal, up to you. Most pumps have acheck valve built in but check since you should have one for the 1 1/2" pipe going outside.

Some tech in sizing..

Sump Pump discharge rates

Sump water flow (GPH)
Water rise in one minute


Sump water flow (GPH)
Water rise in one minute
Sump

Dia... 2".....4"
16".......20....240
18"... 120... 300
20"......180....360
22"... 180... 420
24... 180... 480


Example: An 18" sump with a water rise of 6" per minute represents a flow of 420 US gallons per hour.
Because the sump insert allows ground water to gush in from footing drains and the surrounding gravel bed, the pump has to remove much more water in each cycle than just the volume of the sump insert. During a really heavy storm, the water inflow will be higher so add at least 50 percent to estimate the needed capacity of the backup sump pump.
Then, you have to measure the needed lift – how high has the pump deliver the water from the bottom of the sump pit. A pump can remove much more water at a 5-ft "head pressure" than if has to pump 10 ft. high. Add an extra foot for each elbow.
