Typical 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 or above 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.
UT3P Drive
8.
Power Supply from Circuit Breaker.
Single phase 3-wire, 230 VAC
±
10%.
9.
Power to Motor:
230 VAC, Single phase 3-wire or three phase.
A tank tee is recommended for mounting the tank, pressure sensor (or pressure transducer), 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 or above 100 psi.
•
Install the pressure relief valve near the pressure tank and route to a drain capable of full system flow.
