Self-Priming Shallow Well Jet Pumps
FEATURES
Quality Construction – Close-
grained cast iron body and base,
specially treated for corrosion
resistance. Drain port provided for
easy winterizing.
Built-in Jet –
carbonate nozzle and venturi for
maximum resistance to corrosion and
abrasion. Clean out plug provided for
ease of service.
Noryl Impeller – Precision-molded
for perfect balance… ultra-smooth for
highest performance and efficiency.
Precision Molded Diffuser –
Pump primes faster, handles more air,
with multi-port, precision-molded,
UL778/CSA108
The FN Series provides strong
performance with good pressure
for wells to 25' deep. Self-priming
after the priming chamber has
been filled with water.

Pump will operate at all depths shown, with pressure switch set
at 30-50 PSI.
Tested and rated in accordance with Water Systems Council
Standards.
NOTE: Pumps installed with a PRO-Source™ tank require a
100 PSI relief valve. Pumps installed with a conventional
tank require a 75 PSI relief valve. Relief valve must be
capable of relieving entire flow of pump at relief pressure.
