Pressure Sensing Demand Switch

The PowerFLO Series 7800 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 predetermined ON and OFF
Demand
pressures. Typically, the OFF pressure is accurately set at the
Factory and the ON pressure is within an allowable range below
4.07

that value. In response to the characteristics of the system

in which the pump is installed, the flexibility and length of the

tubing, the faucet or valves and the duration that they are open;
2.13 these pressure settings may vary. Therefore, variation in pressure

When you return your pump for warranty or repair, you must
always do the following:
1. Flush chemical residue from the pump
(best done in the field).
2. Tag pump with type of chemicals having been sprayed
3. Include complete description of operation problem, such as
how pump was used, symptoms of malfunction, etc.
Since pumps can contain residues of toxic chemicals these
steps are necessary to protect all the people who handle return
shipments, and to help pinpoint the reason for the breakdown.
