These pumps are designed for intermittent duty,though most models can be run
continuously for hours at a time. They are commonly used either to pressurize
water from an atmospheric tank, to deliver purified water to a specific point of
use, or simply to increase pressure when required.
These pumps can be controlled by either a pressure switch (“demand” mode) or
an external power control device (“delivery” mode). When required, an integrated
bypass can be incorporated to help regulate pressure levels.
