Refer to the graph to understand how to use the graphs to determine the required motor power or
the maximum allowed pump speed.
To determine the required motor power:
1. Start at the required flow or pump speed (A).
2. Meet the line of the required discharge pressure (B).
3. Read the required motor power (C).
To determine the maximum allowed pump speed:
1. Start at the product temperature (D)
2. Meet the line of the required discharge pressure (E).
3. Read the maximum allowed pump speed (F).
Note: Pump stroke volume is based on new hoses and flooded suction. Actual stroke volume may
vary.
