This is a comparison chart, 4 groups at once — the interesting question is usually how the gap between them changes, not the value of any single group in isolation.

Do not confuse "biggest" with "fastest-growing" — they are frequently different series on a chart like this one, and the gap between them can close faster than the current ranking suggests.

For planning purposes, the end-year figure and the growth rate are the two numbers that matter. Together they show how large the Germany Air Operated Double Diaphragm Pumps market is projected to become and how quickly it gets there.

The numbers here come from a market sizing model: historical revenue estimates up to the 2018 base year, then forecasts through 2026 using growth-rate assumptions for each segment. The underlying report explains the methodology in detail.
