I just require a little advice.
I was just wondering which type of pump would be best.

That is not a 'little advice' ;-)
Before the rest of the group wakes up and starts posting, you might want to
post more info on your [planned?] pond.
How big, plants only or plants and fish, where are you geographically, where
is the pond relative to buildings and trees.
You see where I am going with this?
This is because size matters. A small pump can be installed in the water but
a big unit is more like a swimming pool and would be external.
