Standard Submersible Constant Pressure System
The above drawing illustrates how a typical submersible pump system should be arranged for a constant
pressure application.
1.
Pump and Motor Assembly:
Refer to the Franklin Electric AIM Manual for pump, pipe, and cable sizing
information.
2.
Check Valve
3.
Pressure Relief Valve:
Pressure relief valve must be able to pass full pump flow up to 100 PSI.
4.
Pressure Tank:
Refer to
“Minimum Pressure Tank and Supply Pipe Sizing” on page 15
5.
Pressure Gauge
6.
Pressure Sensor or Transducer:
Install in a vertical position after the pressure tank, and within 6 feet
(1.8 meters) of the tank to minimize pressure fluctuations. There should be no elbows between the tank
and sensor.
7.
SubDrive Utility VFD
8.
Power Supply from Circuit Breaker:
Single phase, 115/230 VAC +/- 10%.
9.
Power to Motor:
Single phase.
Risk of bodily injury or property damage.
•
Pumps can develop very high pressure in some situations. Always install a pressure relief valve able
to pass full pump flow up to 100 psi.
•
Install the pressure relief valve near the pressure tank and route to a drain capable of full system flow.
