The FIMCO 5151087 is the closest match for buyers specifically seeking a 2.4 GPM, 12-volt sprayer pump. The Pumpoasis and ONDAQUA pumps offer slightly higher listed flow, while Everflo trades some flow for a 70 PSI rating. The Fimco High-Flo listing is less clear: its supplied features give a 2.4-gallon capacity, not a confirmed gallons-per-minute rating. Compare flow, pressure, power needs, and chemical resistance before choosing.
| Product | Best for | Listed flow | Pressure |
|---|---|---|---|
| FIMCO 5151087 | Closest 2.4 GPM match | 2.4 GPM | 60 PSI max |
| Pumpoasis 12V | Multi-purpose use | 2.5 GPM | Adjustable, 0–60 PSI |
| Everflo On-Demand | Higher pressure needs | 2.2 GPM | 70 PSI |
| ONDAQUA 12V | Higher-lift transfer needs | 2.5 GPM | Adjustable, 60 PSI |
| Fimco High-Flo | Buyers checking a Fimco pump replacement | Not confirmed | Not listed |
FIMCO 5151087 2.4 GPM Diaphragm Pump
This is the most direct match for a buyer searching for a 2.4 GPM sprayer pump. It runs on 12-volt DC power, has a 10-amp fuse specification, and is rated for a maximum of 60 PSI. Listed materials include Viton valves and a Santoprene diaphragm; the product is also described as approved for use with Roundup.
Best for: Buyers replacing a 12-volt sprayer pump who prioritize a stated 2.4 GPM flow rate. FIMCO says the updated model increases flow from 2.1 to 2.4 GPM and includes improved check valves and optimized chamber flow.
Limitation: The 60 PSI figure is a maximum, not a statement that the pump operates at that pressure in every setup. The listing specifies a 10-amp fuse, so check electrical requirements before installation.
Pumpoasis 12V 2.5 GPM Pump
The Pumpoasis pump is listed at 2.5 GPM and 8 amps, with pressure adjustable from 0 to 60 PSI. Its features include a pressure switch, automatic shutoff, self-priming, and overheat protection. The seller describes it as suitable for agricultural spraying, garden irrigation, RVs, boats, soft wash systems, and household water supply.
Best for: Buyers who want a pump for more than one kind of water or spraying task and can use a 12-volt model with an 8-amp current specification. Its chemical- and corrosion-resistant diaphragm is a stated feature.
Limitation: The listed flow is 2.5 GPM, not 2.4 GPM. The product instructions advise balancing inlet and outlet flow to reduce frequent switch cycling.
Everflo 12V On-Demand Diaphragm Pump
Everflo lists this 12-volt on-demand pump at up to 2.2 GPM and 70 PSI. It can self-prime up to eight feet and has 3/8-inch FNPT ports. The listed construction includes corrosion-resistant Viton valves and a Santoprene diaphragm.
Best for: Buyers who value the listed 70 PSI maximum and self-priming capability more than matching a 2.4 GPM flow target. It is a useful comparison when selecting by pressure and port size as well as flow.
Limitation: Its stated maximum flow is 2.2 GPM, below 2.4 GPM. Confirm that the threaded port size works with the planned plumbing; the supplied product details do not describe included fittings.
ONDAQUA 12V Chemical-Resistant Pump
ONDAQUA lists a 2.5 GPM flow rate and adjustable pressure up to 60 PSI. The pump has a stated 10-foot self-priming height and 114-foot maximum head lift. Its features also include a corrosion-resistant diaphragm, an all-copper motor, automatic shutoff, and thermal protection.
Best for: Buyers comparing a sprayer pump with higher-lift water-transfer needs, such as moving water from a low source to a higher tank. The listing names farm spraying, soft washing, RV water transfer, and garden irrigation as applications.
Limitation: This is a 2.5 GPM model rather than an exact 2.4 GPM match. Check the required flow and pressure for the intended sprayer before substituting it for an existing pump.
Fimco High-Flo Pump Sprayer
The supplied listing identifies this product as a Fimco High-Flo pump sprayer and gives a capacity of 2.4 gallons. It does not provide a flow rate, pressure rating, voltage, or pump material in the supplied features. That makes it difficult to compare directly with 2.4 GPM diaphragm pumps.
Best for: Buyers who recognize the Fimco High-Flo name and are checking whether this listing matches a specific sprayer or replacement need. Its stated capacity may be useful when identifying the product, but it is not a flow specification.
Limitation: Do not assume “2.4 gal” means 2.4 GPM. Verify the pump’s model and technical specifications before buying it as a replacement or comparing its output.
Buying Guide: How To Choose A 2.4 GPM Sprayer Pump
Does the pump need to be exactly 2.4 GPM?
Choose the FIMCO 5151087 when an exact listed 2.4 GPM rating is a priority. The Pumpoasis and ONDAQUA models list 2.5 GPM, while Everflo lists up to 2.2 GPM. A pump’s maximum flow may not represent its output at every pressure, so compare the full specifications with the sprayer’s requirements.
What pressure and electrical details should I compare?
Compare maximum or adjustable PSI with the pressure needed by the sprayer system. Also check voltage, current, fuse requirements, and wiring capacity. Among these options, the FIMCO lists 12V DC and a 10-amp fuse; Pumpoasis lists 12V and 8 amps. Do not treat similar flow ratings as proof that pumps are interchangeable.
Which features matter for chemical use or priming?
Check the pump’s stated diaphragm and valve materials, chemical compatibility, and self-priming details. FIMCO lists Viton valves and a Santoprene diaphragm; Everflo lists those materials and self-primes up to eight feet. Pumpoasis and ONDAQUA describe chemical- or corrosion-resistant construction. Confirm compatibility with the specific liquid and follow the manufacturer’s instructions.
Frequently Asked Questions
What does 2.4 GPM mean on a sprayer pump?
It means the pump is listed to deliver up to 2.4 gallons per minute under its specified operating conditions. Actual output can depend on pressure and the connected system.
Is a 2.5 GPM pump a replacement for a 2.4 GPM pump?
Not automatically. Compare voltage, current, pressure, fittings, chemical compatibility, and the sprayer’s requirements before choosing a replacement.
Does 2.4 gallons mean 2.4 GPM?
No. Gallons describe capacity, while GPM describes flow per minute. The Fimco High-Flo listing supplied here states 2.4 gallons, not a GPM rating.
Why does self-priming matter?
Self-priming describes a pump’s ability to draw liquid into itself from a source, within the stated height and operating conditions. Check the listed limit and installation instructions.
Can these pumps handle every spray chemical?
No. Chemical compatibility varies by pump and liquid. Confirm that the manufacturer lists compatibility with the exact chemical before use.
