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.
4.
Pressure Tank:
Refer to “Minimum Pressure Tank and Supply Pipe Sizing” on page 13 .
5. Pressure Gauge
6.
Pressure Sensor or transducer:
Install in a vertical position.
7. MonoDrive Utility VFD
8.
Power Supply from Circuit Breaker.
Single phase, 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 sensor or pressure transducer 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 sensor.
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.
