Standard Submersible Constant Pressure System
Standard Submersible Constant Pressure System
The above drawing illustrates how a typical submersible pump system should be arranged for a constant
pressure application.

CAUTION
Risk of bodily injury or property damage.
•
Pumps can develop very high pressure in some situations. Always install a pressure re-
lief valve able to pass full pump flow up to 300 psi.
•
Install the pressure relief valve near the pressure tank and route to a drain capable of
full system flow.

(1.8 m) of the tank to minimize pressure fluctuations. There should be no elbows between the tank
and sensor.
