Franklin Electric Turf Boss 1–2 HP Pump Specifications
The 1–2 HP Turf Boss is a close-coupled, self-priming centrifugal sprinkler pump with a cast iron casing, back pull-out service access, 1½-inch inlet and outlet, and a 56J motor arrangement. Standard impellers use Modified PPO thermoplastic; models marked -SSI have a 304 stainless steel impeller.
| Specification | Value |
|---|---|
| Maximum Flow Rate | 70 GPM |
| Maximum Head | 130 feet |
| Maximum Working Pressure | 75 PSI |
| Maximum Water Temperature | 120 degrees F |
| Suction Connection | 1.5-inch FNPT |
| Discharge Connection | 1.5-inch FNPT |
| Pipe Connections | NPT |
| Rotation | Clockwise viewed from motor end |
| Self-Priming Lift | Up to 25 feet |
Performance limits: 70 GPM, 130 feet of head, 25 feet of suction lift and 75 PSI maximum working pressure are separate specifications. The 75 PSI figure is a working-pressure limit, not the discharge pressure delivered at every operating point. Use the model flow table to size a sprinkler system.
Why Install a Turf Boss Self-Priming Sprinkler Pump?
- Timer-operated irrigation: the self-priming design helps the pump restart after the initial casing fill when the suction system retains prime.
- Serviceable construction: back pull-out access lets technicians work on the pump end without disconnecting the fixed suction and discharge plumbing.
- Choice of impellers: select the standard Modified PPO configuration or a model with a 304 stainless steel impeller.
- Electrical options: 1 HP and 1.5 HP single-phase pumps can be wired for 115/230 V; 2 HP single-phase pumps use 230 V. Three-phase models are also available.
- Practical maintenance: an integral 1-inch NPT priming port, drain plug and model-specific replacement parts support seasonal service.

| 92983020 | FTB2CI-SSI-T | 2 | 3 | 208-230/460 V | 304 stainless steel | 1.5″ x 1.5″ | 57 lb |
Motor selection: the listed single-phase models have ODP enclosures. The listed three-phase -SSI-T models use 208–230/460 V in Franklin’s Turf Boss brochure; verify the actual nameplate voltage before purchasing or wiring a replacement. Select horsepower using required flow, total suction lift and discharge pressure, not horsepower alone.
How Much Water Can Each Turf Boss Pump Deliver?
As a useful comparison from Franklin Electric’s performance table, with 5 feet total suction lift and 40 PSI discharge pressure, the 1 HP FTB1CI is rated for 27 GPM, the 1.5 HP FTB15CI for 48 GPM, and the 2 HP FTB2CI for 65 GPM. Different suction lifts or discharge pressures change the available flow. See the full performance table further down the page.
Turf Boss Pump-End Kits for 56J Motors, Motor Not Included
If you have a suitable existing motor, a Turf Boss pump-end kit may be the right replacement rather than a complete motor-driven pump. These six pump-only assemblies cover 1, 1.5 and 2 HP, with both standard and stainless steel impeller variants. The pump ends connect to 1½-inch suction and discharge piping and weigh 28 lb each.
| Franklin Item No. | Pump-End Model | HP | Impeller | Suction × Discharge | Wt. |
|---|---|---|---|---|---|
| 92940010 | TB1CI-PE | 1 | Modified PPO | 1-1/2″ x 1-1/2″ | 28 lb |
| 92940015 | TB15CI-PE | 1.5 | Modified PPO | 1-1/2″ x 1-1/2″ | 28 lb |
| 92940020 | TB2CI-PE | 2 | Modified PPO | 1-1/2″ x 1-1/2″ | 28 lb |
| 92941010 | TB1CI-SSI-PE | 1 | 304 stainless steel | 1-1/2″ x 1-1/2″ | 28 lb |
| 92941015 | TB15CI-SSI-PE | 1.5 | 304 stainless steel | 1-1/2″ x 1-1/2″ | 28 lb |
| 92941020 | TB2CI-SSI-PE | 2 | 304 stainless steel | 1-1/2″ x 1-1/2″ | 28 lb |
Check the motor first: the motor must have the correct 56J C-face, threaded shaft arrangement and sufficient horsepower and service factor for the selected pump end. Ask for pump-end pricing using the linked Franklin item number and your motor nameplate details.
Franklin Electric Turf Boss Replacement Parts, Seals and Overhaul Kits
Repair a worn Turf Boss pump by identifying the exact 1–2 HP model and the component shown in the exploded drawing. Franklin Electric lists common bracket, mechanical seal, pump case and elastomer parts, plus separate overhaul-kit numbers for every horsepower and impeller material. These part numbers are for the 1–2 HP range, not the different 3–5 HP design.

| 305396919 | Elastomer set, mechanical seal, O-ring, diaphragm, grommet | All 1–2 HP models | 3, 4, 9, 10 |
What is included in an overhaul kit? Each listed impeller overhaul kit includes the impeller, wear ring, diffuser, diffuser screws, mechanical seal, case bolts, diaphragm and grommet. The 305396901–305396903 series is for plastic/Modified PPO impellers; 305396904–305396906 is for stainless steel impellers. Confirm the model and impeller material before ordering.
Repair-parts quote: send Ken’s Distributing the pump model or nameplate photo, original impeller material, any exploded-view item reference, and the Franklin repair-part number. For a seal leak or damaged case, ask about the individual part. For several worn hydraulic components, request the matching overhaul kit. A damaged motor or incompatible pump end may make a complete replacement pump more practical.

Applications and Pump Selection Tips
- Lawn and turf irrigation: residential sprinklers, landscape zones and light-commercial timer-operated systems.
- Clean-water transfer: tanks, reservoirs and suitable surface-water sources when suction conditions are within the pump’s operating limits.
- Priming and suction layout: fill the pump casing before initial use, keep suction connections airtight, and follow the manufacturer instructions for foot valves and suction-line routing.
- Clean liquid service: Franklin Electric specifies that Turf Boss is not for solids or abrasive fluids. Maximum liquid temperature is 120°F.
- Seasonal service: use the built-in drain plug when freezing is possible and inspect seals and hydraulic wear parts as needed.
1–2 HP Turf Boss vs. Larger Pumps
The 1–2 HP line uses 56J motors and 1½-inch suction and discharge connections. If your required duty point exceeds its available flow and head, compare the Turf Boss 3–5 HP pumps, which use a different hydraulic and motor arrangement and incorporate a built-in suction check valve. Check the performance data before moving to a larger size.
Frequently Asked Questions About Turf Boss Pumps and Parts
Is the Franklin Electric Turf Boss 1–2 HP pump self-priming?
Yes. After the pump housing is initially filled, it can self-prime under suitable suction conditions with a published maximum suction lift of 25 feet.
What is the difference between FTB1CI and FTB1CI-SSI?
Both are 1 HP complete pumps, but the standard FTB1CI uses a Modified PPO impeller and the FTB1CI-SSI uses a 304 stainless steel impeller. Match impeller construction when ordering an overhaul kit.
Which models have 115/230 V single-phase motors?
FTB1CI and FTB15CI, including their -SSI single-phase versions, are listed for 115/230 V. The 2 HP single-phase configurations use 230 V.
Can I buy the pump without a motor?
Yes. Choose the correct TB-series pump-end item in the table above. Verify 56J shaft fit and motor service factor before replacing only the pump end.
Which repair kit fits a 1.5 HP Turf Boss?
Franklin lists 305396902 for the 1.5 HP plastic-impeller overhaul kit or 305396905 for the 1.5 HP stainless steel impeller overhaul kit. Match the model and original impeller material.
What is the mechanical seal part number?
The current Franklin Turf Boss 1–2 HP owner’s manual identifies 305421907 as the mechanical seal, listed for all models in that 1–2 HP family.
Does the 75 PSI working pressure rating mean it produces 75 PSI?
No. It is a maximum working-pressure rating. Actual pump discharge pressure and flow depend on horsepower and the system duty point.
