Well water levels do not stay put, and that is the whole case for a Franklin Electric convertible jet pump. It runs as a shallow well pump today and converts to deep well service later with an injector kit, so a dry summer does not mean a new pump. This page compares the C Series and the Convertible Pro (RM2) and walks through the conversion.
Both series sit above ground in a heavy cast iron case with a stainless steel impeller. Both come with a pressure switch set at 30/50 psi.
Shallow Today, Deep Tomorrow: Is Convertible Right for You?
A convertible jet pump is right for your well when the water level is near 25 feet, drops in dry months, or already sits deeper. It works as a shallow well pump now and switches to deep well mode with an injector. Pick the C Series for standard homes, or the RM2 for more flow, more pressure, and lifts up to 100 feet.
Shallow Mode vs. Deep Mode
In shallow well mode, the pump pulls water up one suction pipe. The injector that creates the suction sits in or at the pump, so everything stays above ground.
In deep well mode, a deep well injector kit goes down the well on two pipes. One pipe sends drive water down to the injector, and the other brings the lifted water back up. On the RM2, you replace the internal shallow well injector with a bypass plug when you make this switch.
- Shallow mode: one pipe, simplest install, lift up to 25 feet.
- Deep mode: two pipes and a down-hole injector, lift up to 100 feet on the RM2.
- What to tell us: your well casing size, your static water level, and how far the level drops while pumping.
C Series and Convertible Pro (RM2)
C Series Cast Iron Convertible Jet Pump
The C Series is the straightforward choice for a single-family home. It converts between shallow and deep well use with a screw-in injector and a bypass plug. The deep well injector kit is ordered separately, so you only buy it if you need it.
Convertible Pro (RM2) Series
The RM2 is built for harder jobs. Its 150 psi rating and 23 GPM flow suit larger homes, farms, and light commercial wells. The keyed shaft motor comes off for service without disturbing the plumbing, and the 1RM2-T model runs on three-phase power.

The two series work the same way, but the RM2 delivers more flow, pressure, and lift.

Staying Under 25 Feet, or Already on City Water?
If your water always stays well within 25 feet of the surface, you can skip the conversion hardware. The shallow well jet pump models are simpler and include the VersaJet Pro with swappable nozzles.
If you already have city water and only need more pressure, a well pump is the wrong tool. Look at Franklin booster pumps instead.

Frequently Asked Questions
What is a convertible jet pump?
A convertible jet pump is an above-ground well pump that can run as a shallow well pump or a deep well pump. In shallow mode it lifts water up to about 25 feet through one suction pipe. Add a deep well injector kit and a second pipe, and the same pump reaches deeper water. The Franklin Convertible Pro (RM2) lifts water up to 100 feet in deep well mode. This makes a convertible pump a good fit when your water level is uncertain or changes by season.
What is the difference between a convertible jet pump and a standard jet pump?
The difference between a convertible jet pump and a standard jet pump is how deep each one can reach. A standard shallow well jet pump keeps its nozzle and venturi inside the pump and stops at about 25 feet of lift. A convertible jet pump can run the same way, or switch to deep well mode with a down-hole injector and a second pipe. That lets the Franklin RM2 reach water up to 100 feet. You pay for the extra hardware only if you need the depth.
How do you set up a jet pump for a deep well?
To set up a convertible jet pump for a deep well, you add a deep well injector kit and run two pipes down the well. The drive pipe sends water down to the injector, and the suction pipe brings lifted water back up to the pump. On the C Series, the deep well injector kit is ordered separately. On the RM2, you swap the internal shallow well injector for a bypass plug. Send us your casing size and pumping water level so we can match the kit.
