Series 420 & 447
This handbook will discuss the basic sizing used
for our larger Well-X-Trol
440, and 450 series. This allows you to use the Well-
X-Trol
"principle of separation of air and water" on
®
larger jobs that are beyond the typical residential
range.
The Well-X-Trol
models we'll be working with in
®
this handbook are listed in Table 1.
The design features of these larger models allow
us to apply them more creatively than the smaller
residential models found in the Well-X-Trol
200, and 250 series.
The Larger Well-X-Trol
for Maximum Acceptance on Each Operating
Cycle
In the smaller residential Well-X-Trol
is for basic intermittent use and for the usually
found in residential applications. Standard pressure
ranges of (20) PSIG (between pump cut-in and
pump cut-out) are used.
In these applications, full use of the maximum
acceptance volume of the Well-X-Trol
required to meet job conditions.
