Max lift / suck distance for a GHL doser?

[alekslyse]

If I want to use the GHL doser for a AWC or ATO, how far and height can the GHL doser 2.1 be able to suck water through its tubes?

[Vinny]

Each pump will be able to push and pull horizontally from about 50ft away.

Vertical distance is about 25ft.

We do not recommend exceeding 50ft of total distance per way.

technically the distances are possible, but they don't make much sense in most applications
