Brands/model of a high lph return pump

[nzsilentone]

I'm moving house in a few weeks and my current setup is my 450L tank has a sump on the otherside of the wall.

This new house there will be approx 10metres of piping needed to get them working together.

Approx 7m horizontally and 3m vertically - So would need about 4500 LPH after the loss due to the length of the piping.


Any suggestions for a brand or model of pump that will meet my needs? How can i calculate what size piping i need to use?


Thanks!

For a start i was looking at the Atman MP-20000
