Jabsco Marine Pumps Online – Pump Supplier & Part Numbers
Looking for the right Jabsco marine pump? Start with the part number.
Two Jabsco pumps can look almost identical while having different impeller materials, port sizes, drive arrangements or specifications. That is why identifying the exact pump before ordering matters.
Alfa Marine Spare Parts supplies Jabsco marine pumps and pump parts for yachts, commercial vessels, workboats and other marine applications.
If you already have the Jabsco pump number, send it together with the quantity required. If the number is missing or difficult to read, clear photos and application details can help with identification.
Where Are Jabsco Pumps Used Onboard?
Jabsco pumps are used across a wide range of marine systems.
Depending on the specific pump model, applications can include:
- Marine engine cooling
- Seawater circulation
- Bilge pumping
- Water circulation
- Washdown duties
- General fluid transfer
Flexible impeller pumps are particularly common in marine applications because they are compact and self-priming.
Not every pump is suitable for every application, so always check the exact model and specification before ordering.
Why Does the Exact Jabsco Pump Number Matter?
Let's look at a few examples.
Jabsco 2620-1101
The Jabsco 2620-1101 is a self-priming flexible impeller pump with a bronze body, 316 stainless-steel shaft, 3/8-inch NPTF ports and a neoprene impeller.
The 2620 series can be used for marine duties including engine cooling, bilge pumping and water circulation.
Jabsco 2620-1103
The Jabsco 2620-1103 belongs to the same pump family, but there is an important difference.
The 2620-1101 uses a neoprene impeller, while the 2620-1103 uses a nitrile, oil-resistant impeller.
This is a good example of why the complete pump number matters.
Jabsco 18660-0121 and 18660-0123
Here's another example where a small difference in the part number matters.
Jabsco 18660-0121
The Jabsco 18660-0121 is a 12 VDC electric flexible impeller pump with a bronze body and neoprene impeller.
It uses 1/2-inch NPTF internal pipe threads and a permanent-magnet motor.
Jabsco 18660-0123
The Jabsco 18660-0123 is also a 12 VDC bronze electric flexible impeller pump, but this version uses a nitrile impeller.
Two very similar pump numbers, but an important difference in specification.
Jabsco 3890-9011
The Jabsco 3890-9011 is a pedestal flexible impeller pump with a bronze body, neoprene impeller and 3/4-inch NPT connections.
Applications for this type of pump can include marine engine cooling, circulation, bilge pumping, washdown and fluid transfer.
When replacing an existing 3890-9011, use the complete model number rather than simply searching for a similar-looking pump.
Jabsco 42730-0000
The Jabsco 42730-0000 is a flexible impeller pump used for marine engine-cooling applications.
For an engine cooling pump, the existing pump number and engine information can be useful when confirming the correct replacement.
Send:
- Pump number
- Engine manufacturer
- Engine model
- Engine serial number, when available
- Quantity required
- Clear photos if identification is uncertain
Jabsco 29860-2201
The Jabsco 29860-2201 belongs to Jabsco's larger pedestal flexible impeller pump range.
With larger pumps, identification should go beyond appearance. Check the complete model number together with the port configuration, drive arrangement and required operating conditions.
A pump that looks similar isn't automatically the correct replacement.
Can't Read the Number on Your Old Jabsco Pump?
This happens regularly in marine applications.
A pump may spend years in a hot, wet and salty engine room. Eventually the identification plate can become dirty, painted over or corroded.
Don't guess.
Take clear photos showing:
- Complete pump
- Identification plate
- Inlet and outlet connections
- Mounting arrangement
- Shaft or drive
- Any numbers still visible
If the pump is fitted to a marine diesel engine, also send the engine make, model and serial number when available.
Even a partially readable number can help with identification.
Is It the Pump or Just the Impeller?
A damaged flexible impeller doesn't automatically mean you need a complete new pump.
If the housing, shaft, seals and other major parts remain in good condition, replacing the impeller may be enough.
Take a closer look if you find:
- Excessive shaft movement
- Persistent water leakage
- Heavy corrosion
- Housing damage
- Worn internal surfaces
- Repeated impeller failures
The condition of the complete pump should be considered before deciding whether an impeller replacement is enough.
Why Does My Jabsco Impeller Keep Failing?
If you've replaced the impeller and it fails again, don't simply install another one without investigating the cause.
Check for:
- Restricted suction
- Blocked strainers
- Restricted through-hull fittings
- Air leaks on the suction side
- Restricted discharge
- Incorrect pump speed
- Pump wear
- Incorrect impeller material
Flexible impeller pumps depend on the pumped liquid for lubrication. Dry running can quickly damage an impeller, so always follow the operating instructions for the specific pump model.
How Do I Identify the Correct Jabsco Impeller?
Knowing the pump model is the easiest starting point.
If the pump number isn't available, useful information can include:
- Impeller outside diameter
- Impeller depth
- Shaft diameter
- Number of blades
- Drive type
- Impeller material
Don't select an impeller simply because it looks approximately the same size. Small dimensional or drive differences can matter.
