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
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, the flexibility and length of the
tubing, the faucet or valves and the duration that they are open;
these pressure settings may vary. Therefore, variation in pressure
setting is expected with use and over time.
Standard Warranty
Delavan warrants PowerFLO Series Pumps for a period of two
years from date of manufacture.
All products sold by Delavan are warranted only to purchasers
from Delavan for resale or for use in purchasers’ own business
or original equipment manufacture, against defects in
workmanship or materials under normal use, maintenance and
service (rental use excluded).
The sole and exclusive obligation of Delavan under this or any
implied warranty shall be to replace or, at its option, to repair,
without charge, any product which is determined by Delavan
to be defective in workmanship or materials after the product is
returned to the Delavan factory*, shipping costs prepaid.
In no event shall Delavan be liable to any person for indirect
or consequential damages or for injury or commercial loss
resulting from any use or inability to use any Delavan product.
Delavan expressly negates any other warranty, express or
implied, including any warranty of merchantability or fitness for

custom or usage of trade.
No person, including any dealer or representative of Delavan,
is authorized to make any representation or warranty on behalf

Purchasers to whom these provisions apply agree to hold
Delavan harmless from claims by their customers in excess of
the obligations of Delavan expressly set forth herein
* Important return safety instructions:
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.
