Determining Output for Dual Head Dual
Control Models

• The dial ring for adjustable pumps is marked
L-10; L=5%, 1-10 indicates 10% increments of
maximum output.

• The turndown ratio is 20:1.

• On the MDC models, the outer pump head
operates on a percentage of the inner head
(closest to the motor).

• Setting #10 on both pump heads will deliver the
pump’s maximum output and is the only time each
pump head will output the same amount.

Example Using 100MDC5

• Decide on the desired output for the inner head.

• Note the setting on the dial ring that represents the
desired output.

For example setting #4 = 40% of max output
In the 100MDC5 model, setting #4 = 20 GPD

• Repeat the above steps to calculate the output of the
outer head.

Using setting #3 in this example,
#3 = 30% of the inside head output
20 GPD x 30% = 6 GPD

In this example using pump model 100MDC5,
the output for the inside head would be 20 GPD
and 6 GPD for the outside head.

#8 = 13.6 GPD

• Repeat the above steps to calculate the output of the
outer head.

Using setting #6 in this example,
#6 = 60% of the inner head output

13.6 GPD x 60% = 8.5 GPD

In this example using pump model 170MDCHP34, the
output for the inner head would be 13.6 GPD and

8.5 GPD for the outer head.
