How to use the graphs
A:
Required flow or pump speed
B:
Required discharge pressure
C:
Required motor power
D:
Product temperature
E:
Required discharge pressure
F:
Maximum allowed pump speed
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 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).
