What Makes the Convertible Pro RM2 Different?
The Franklin Electric Convertible Pro RM2 is designed for customers who need an accessible surface-mounted pump with the flexibility to serve either a shallow or deeper well. The cast iron pump body and stainless steel impeller handle clean-water transfer, while the adjustable pressure switch and standard motor configurations make the series practical for pressure-tank systems. Its 56C keyed-shaft coupling also makes motor servicing more convenient without disconnecting the pump from the plumbing.
- Shallow- and deep-well flexibility: An internal shallow-well injector is provided for typical shallow-well setups; a matching external injector enables deep-well operation.
- High service factor motor: 56C-frame motor and keyed-shaft coupling allow access during servicing.
- Cast iron construction: Durable casing with a stainless steel closed impeller and precision-molded thermoplastic diffuser.
- Factory-installed controls: Adjustable 30/50 PSI pressure switch for pressure-tank applications.
- Model choice: Three single-phase selections plus a 1 HP three-phase option for sites with compatible electrical service.
- Serviceable hydraulic parts: Mechanical seal and pump components can be identified by the exact model and item number.
Shallow-Well and Deep-Well RM2 Setup
Shallow-Well Operation
For a pumping water level within the practical shallow-well range, the RM2 uses its internal shallow-well injector and a suitable airtight suction line. Franklin Electric lists shallow-well injector operation for suction lifts of approximately 5–25 feet. Actual delivery depends on suction height, pump size, pipe friction and operating pressure.
Deep-Well Operation
For deeper installations, the internal injector is replaced with the appropriate bypass plug and an external two-pipe deep-well injector assembly is installed. The required injector depends on the exact RM2 model and total suction lift; deep-well injector kits are ordered separately. Franklin lists a minimum 4-inch inside well diameter for the applicable deep-well injector configurations.
RM2 Deep-Well Injector Selection by Model
Use the pump model and actual pumping water level to identify a matching deep-well injector. These are manufacturer-listed part numbers, not links to separate injector listings.
| RM2 pump model | 30–60 ft injector | 50–100 ft injector |
|---|---|---|
| FP05CI-C (1/2 HP) | 147E1120 | 147E0915 |
| FP07CI-C (3/4 HP) | 147E1023 | 147E1118 |
| FP1CI-C (1 HP) | 147E1125 | 147E1120 |
| 1RM2-T (1 HP, three-phase) | Confirm 30–60 ft configuration | 147E1120 |
Ordering tip: Give Ken’s Distributing both the pump item number and required operating water level. Deep-well injector components are selected separately from the pump; injector compatibility and piping requirements should be confirmed before ordering.
RM2 Performance: Flow at Actual Operating Pressure
Pump horsepower and a series-wide maximum GPM number do not tell you how much water will reach the pressure tank. The following selected flow figures are from Franklin Electric’s published RM2 shallow-well data at 5 ft suction lift and 50 PSI discharge pressure with the listed standard setup. Use them to understand how differently the models perform at the same operating point.
| Model | HP | Flow at 50 PSI / 5 ft suction lift |
|---|---|---|
| FP05CI-C | 1/2 HP | 2.5 GPM |
| FP07CI-C | 3/4 HP | 6.2 GPM |
| FP1CI-C | 1 HP | 14.0 GPM |
The 1RM2-T three-phase variant should be sized using its applicable performance data. For higher lifts or different discharge pressures, request model-specific performance information before choosing an injector and pump.
RM2 Dimensions and Product Weights
Approximate pump dimensions and weights help compare replacement-pump space and handling requirements. Check clearances on the exact unit before installation.
| Model | Horsepower | Pump length | Product weight |
|---|---|---|---|
| FP05CI-C | 1/2 HP | 18.65 in. | 48 lb |
| FP07CI-C | 3/4 HP | 19.15 in. | 51 lb |
| FP1CI-C | 1 HP | 19.65 in. | 53 lb |
| 1RM2-T | 1 HP | 19.06 in. | 53 lb |
RM2 vs. Franklin Electric C Series Convertible Jet Pumps
Both series are cast iron convertible jet pumps for shallow- and deep-well water supply. The RM2 adds a 1 HP choice and a three-phase model, along with a serviceable 56C keyed-shaft motor arrangement. The C Series uses a 56J threaded-shaft motor and is offered in 1/2 and 3/4 HP configurations. Choose between them based on the flow and pressure needed at your operating water level, compatible injectors, and existing equipment.
| Selection factor | Convertible Pro RM2 | C Series Convertible |
|---|---|---|
| Horsepower range | 1/2, 3/4 and 1 HP | 1/2 and 3/4 HP |
| Three-phase configuration | 1 HP model available | No model listed in supplied series lineup |
| Motor arrangement | 56C-frame keyed shaft and coupling | 56J threaded shaft |
| Pump construction | Cast iron casing, stainless steel impeller | Cast iron casing, stainless steel impeller |
| Pump maximum working pressure | 150 PSI | 150 PSI |
| Deep-well operation | Model-matched external injector | Model-matched external injector |
| Best selection approach | Compare required flow, pressure, lift and motor supply | Compare required flow, pressure, lift and motor supply |
A 150 PSI maximum working-pressure rating describes the pump’s pressure limit, not its normal delivery pressure. Actual operating performance depends on the model and injector selected.
Typical Applications
- Residential well systems: Pressurized clean-water supply for homes using compatible shallow or deep wells.
- Cabins and rural properties: Serviceable surface-mounted well pump connected to a properly selected pressure tank.
- Farms and outbuildings: Fresh-water transfer for light agricultural and utility uses within the selected pump’s performance range.
- Light commercial water supply: Water delivery where the selected motor phase and flow requirements are suitable.
- Irrigation and tank filling: Small water-transfer duties matched to available flow and discharge pressure.
Installation and Compatible Accessories
Plan around the pumping water level, not just the drilled depth of the well. A shallow-well pump draws through suction piping, while the RM2 deep-well configuration requires the appropriately matched external injector and separate piping arrangement. Both setups also need a correctly sized pressure tank and suitable electrical supply.
- Pressure tank and switch: Match the pressure tank and its precharge to the factory-set 30/50 PSI switch and system design.
- Injector and plumbing: Match the model and lift to the correct external injector for deep-well service; maintain airtight suction connections.
- Power: Verify whether the installation requires 115/230V single-phase or 230/460V three-phase supply before choosing an item number.
- Maintenance: Use the model and item number when requesting mechanical seals, impellers, injectors, bypass plugs and gaskets.
- Commissioning: Prime and configure the pump according to the installation requirements before operation.
Franklin Electric RM2 Frequently Asked Questions
Is the RM2 a shallow-well or deep-well jet pump?
Both. It is a convertible jet pump with a factory-provided shallow-well injector. For deep wells, the correct external injector assembly and bypass arrangement are needed.
How deep can an RM2 pump lift water?
