Series 420 & 447 Pressure Switch

This handbook will discuss the basic sizing used for our larger Well-X-Trol®ssuch as WX-400, 420, 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®100, 200, and 250 series.

The Larger Well-X-Trol®s are Designed and Built for Maximum Acceptance on Each Operating Cycle

In the smaller residential Well-X-Trol®s, the design 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®is rarely required to meet job conditions.
