None of the listed pumps is rated for 100 gallons per minute (GPM). Their stated maximum flows range from 23 to 35 GPM, so they are not a match if your system truly requires 100 GPM. For deep wells, the iMeshbean and Hallmark submersible pumps offer the highest listed flows; for shallow wells, the 1 HP jet pumps are rated up to 23 GPM.
| Product | Listed maximum flow | Best suited for |
|---|---|---|
| iMeshbean 1 HP Submersible | 33 GPM | Deep-well buyers seeking a 110V pump |
| Hallmark Industries 2 HP Submersible | 35 GPM | Deep-well buyers prioritizing higher listed lift |
| Red Lion RJS-100-PREM | 23 GPM | Shallow-well buyers seeking a named-brand model |
| czobloik 602208 Jet Pump | 23 GPM | Shallow wells up to 25 feet |
| A-Outsanding 1 HP Jet Pump | 23 GPM | Shallow-well buyers wanting dual voltage |
iMeshbean 1 HP Deep-Well Submersible Pump
Best for: Deep-well users who need a submersible pump with a stated 110V supply and a listed maximum flow higher than the shallow-well options here. It is rated at up to 33 GPM and a 305-foot maximum lift, with a 100-foot power cord.
The pump is 4 inches in diameter, has a 1-1/2-inch NPT discharge, and includes an external control box and check valve. The listing says it fits a 4.3-inch or larger casing.
Limitation: Its maximum listed flow is 33 GPM, not 100 GPM. The listing also specifies its dimensions and connection, so confirm the well casing and plumbing requirements before choosing it.
Hallmark Industries 2 HP Deep-Well Pump
Best for: Deep-well buyers comparing pumps by listed horsepower, flow, and lift. This stainless-steel submersible model is listed at 2 HP, 230V, up to 35 GPM, and 420 feet.
Its stated 35 GPM is the highest flow among the products in this guide. Choose it if the listed electrical supply and lift specifications suit the intended installation.
Limitation: The supplied product information is brief and does not provide additional connection, casing, or included-component details. Its maximum flow remains well below 100 GPM.
Red Lion RJS-100-PREM Shallow-Well Jet Pump
Best for: Home, agricultural, or irrigation users who need a shallow-well jet pump and want a model with specified port sizes. The 1 HP pump is rated up to 23 GPM and operates on either 115V or 230V, with the voltage selected to match the incoming power.
It has a cast-iron casing and volute, a glass-filled thermoplastic impeller and diffuser, a 1-1/4-inch FNPT suction intake, and a 1-inch FNPT discharge. The listing also notes a capacitor for starting power.
Limitation: This is a shallow-well jet pump, not a deep-well submersible model. Its listed maximum flow is 23 GPM, and voltage selection must match the power source.
czobloik 602208 Shallow-Well Jet Pump
Best for: Buyers with a shallow well up to 25 feet who need a 1 HP jet pump with a stated 23 GPM maximum. The dual-voltage pump has a factory preset 30/50 pressure switch and a pressure gauge, according to the listing.
Its cast-iron casing and volute are described as corrosion- and rust-resistant. Connections are listed as 1-1/4-inch FNPT suction and 1-inch FNPT discharge. The instructions specify filling the inlet with water before startup.
Limitation: The stated well-depth range is limited to shallow wells up to 25 feet. The pump must be primed as instructed, and it does not approach 100 GPM.
A-Outsanding 1 HP Shallow-Well Jet Pump
Best for: Shallow-well buyers who want a cast-iron 1 HP pump with dual-voltage options. The listing gives a maximum flow of 23 GPM, a maximum pressure of 65 PSI, and a maximum head lift of 150 feet.
The stated motor options are 115V and 230V, with listed current of 17.6A and 8.8A, respectively. The product is presented for home water supply, farms, cabins, garden sprinklers, and irrigation.
Limitation: The listing does not establish that the pump can deliver its maximum flow and maximum lift simultaneously. Its 23 GPM maximum is unsuitable for a requirement of 100 GPM.
Buying Guide
Does a 100 GPM well pump have to deliver 100 GPM?
If your application genuinely requires 100 GPM, none of these listed models meets that stated flow target. Look for a pump with a documented capacity at the required operating conditions, rather than selecting by horsepower or maximum-flow claims alone. Ask the supplier for a performance curve or operating data that matches your well and system.
Should you choose a submersible or jet pump?
Compare the pump type with the well setup. The iMeshbean and Hallmark products are submersible pumps listed for deep-well use. The Red Lion, czobloik, and A-Outsanding models are shallow-well jet pumps. Do not treat a shallow-well rating as a substitute for deep-well specifications.
Which specifications should you check?
- Required flow: Compare the system’s actual GPM need with the pump’s documented output.
- Lift and pressure: Check the required vertical lift and pressure against the manufacturer’s specifications.
- Power supply: Confirm voltage and current requirements. Dual-voltage models require the correct voltage selection.
- Connections and fit: Match the stated port sizes and, for submersible models, casing dimensions.
- Installation details: Check priming instructions and any listed control-box or valve requirements.
Frequently Asked Questions
Is any pump in this guide rated for 100 GPM?
No. The listed maximum flows range from 23 to 35 GPM.
Which listed pump has the highest maximum flow?
The Hallmark Industries model has the highest listed maximum flow, at 35 GPM.
Which options are intended for shallow wells?
The Red Lion, czobloik, and A-Outsanding products are shallow-well jet pumps. The czobloik listing specifies wells up to 25 feet deep.
Which product is listed with the greatest lift?
The Hallmark Industries pump is listed with a 420-foot lift. The iMeshbean pump is listed with a 305-foot maximum lift.
Can a pump’s maximum GPM be assumed at every lift height?
No. The listings provide maximum figures, but the supplied information does not establish that maximum flow is available at maximum lift. Verify the pump’s performance data for the actual operating conditions.
