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 Franklin Electric Motor. 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 at 100 PSI.
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 at 100 psi.
• Install the pressure relief valve near the pressure tank and route to a drain capable of full sys-
tem flow.
4. Pressure Tank: Refer to
5. Pressure Gauge
6. Pressure Sensor or Transducer: Install in a vertical position.
7. SubDrive Utility VFD
8. Power Supply from Circuit Breaker. Single phase, 115/230 VAC +/- 10%.
9. Power to Motor: Single phase.
A tank tee is recommended for mounting the tank, pressure sensor, pressure gauge, and pressure
relief valve. If a tank tee is not used, the pressure transducer or pressure sensor should be within 6
feet (1.8 meters) of the pressure tank to minimize pressure fluctuations. There should be no elbows
between the tank and pressure transducer or pressure sensor.
