Frequently asked questions

What is the maximum head of the 4DFS (AC/DC) series?

Maximum head ratings range from 12–183 m across 25 models. Select a model using its performance curve at your required total dynamic head, including elevation, pressure and pipe friction losses.

How much water can the 4DFS (AC/DC) series deliver?

Maximum flow ratings range from 5.7–27 m³/h. Actual flow depends on operating head and available power. Maximum head and maximum flow are separate ratings; check the performance curve for your operating point.
