The basic demand pump is controlled by a built-in pressure
sensing demand switch. When a faucet or valve is opened
down stream of the pump, line pressure drops, thus starting
the pump automatically. Conversely, when the valve shuts,
the line pressure increases turning the pump off automatically.
The pressure switch actuates in response to the pump outlet
pressure at a predetermined and preset pressure. The pump
label indicates the pre-set OFF pressures. Typically, the OFF
pressureisaccuratelysetattheFACTORYandtheONpressure
is within an allowable range below that value. In response to
the characteristics of the system in which the pump is installed,
suchastheexibilityandlengthofthetubing,andthefaucet
or valves and the duration that they are open, these pressure
settings may vary. Therefore, change in pressure settings is
expectedwithuseandovertime.
