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 at 300 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 up to 300 psi.
•
Install the pressure relief valve near the pressure tank and route to a drain capable of full system flow.
4. Pressure Tank: Refer to
5. Pressure Gauge
6. Pressure Transducer or Sensor: 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 Connect Plus VFD
8. Power Supply from Electrical Panel: Single phase (shown) 208/230 VAC ± 10%, three phase 230 VAC
±10%, or three phase 460 VAC ±10% (depending on drive model rating).
9. Power to Motor: Three-Phase voltage depending on drive model rating.
