The best oil free air compressor replacement pumps include the Bonbo KK-4835 Compressor Piston Kit Connecting Rod for compatible oil free pump rebuilds, the VEVOR Air Compressor Motor for a complete oil free pump unit, and the VEVOR Air Compressor Pump Head for belt driven twin cylinder systems.
On this page (5 sections)
The best oil free air compressor replacement pump is the Bonbo rebuild kit when your existing pump matches its listed models; for a complete oil free unit, consider the VEVOR motor and pump. The other pumps below are oil lubricated or have unconfirmed oil free compatibility, so compare their system fit carefully.
A replacement pump is a system match, not just a horsepower match. Check the compressor model, original pump type, motor, mounting, drive, pressure and required airflow before you buy.
If the tank needs replacing, compare horizontal air compressor replacement tanks.

How we chose oil free air compressor replacement pumps
We compared the stated part fit, pump type, airflow and drive details against the needs of someone repairing an existing compressor. A rebuild kit, a complete oil free unit and an oil lubricated pump head do different jobs, so the score reflects fit for this search rather than horsepower alone.
These options don't all qualify as oil free replacements. The Bonbo kit is for rebuilding compatible oil free pumps, and the VEVOR motor is explicitly oil free; the remaining assemblies are oil lubricated or don't identify an oil free design.
If you need a full assembly beyond the models here, compare the broader best replacement pump for an air compressor guide. For oil free basics and terminology, see what an oil free air compressor is.

The best oil free air compressor replacement pump options
The Bonbo kit is the closest match for a repair that keeps a compatible oil free pump in service, while VEVOR offers a complete oil free motor and pump. The remaining picks suit different compressor systems only when their oil lubrication and fit requirements match.
Bonbo KK-4835 Compressor Piston Kit Connecting Rod: Best for compatible oil free pump rebuilds
- For listed Sears, Craftsman, DeVilbiss, DeWalt and Porter Cable pumps
- Includes connecting rod, piston ring, cylinder sleeve and 2 O-rings
- Comparable to KK-4835, KK-5081 and A02743
A targeted internal rebuild kit for compatible oil free pumps, rather than a complete replacement pump. Check the compressor model and part number before ordering.
Pros
- Names compatible pump brands and models
- Includes several core rebuild parts
- Designed for oil free pump service
Cons
- Not a complete pump assembly
- Compatibility is limited to named models
The Bonbo KK-4835 kit is the most direct choice here for rebuilding a compatible oil free pump. It includes a connecting rod, piston ring, cylinder sleeve and 2 O-rings, so it replaces several internal wear parts without requiring a complete pump assembly.
Compatibility is the key condition. Bonbo names Sears, Craftsman, DeVilbiss, DeWalt and Porter Cable pumps, along with a long set of model numbers and comparable part numbers KK-4835, KK-5081 and A02743.
Before ordering, compare the compressor nameplate and old part with those references. A similar brand or pump shape alone is not enough to establish fit.
Choose this kit when the failed parts are inside a pump that matches its application. If the cylinder or other core parts are beyond repair, compare a complete assembly instead.
VEVOR Air Compressor Motor: Best for a complete oil free pump unit
- Oil free, single stage design
- 2 HP and 5.2 CFM at 90 PSI
- Maximum pressure of 145 PSI
- 78 dB stated noise level
A complete oil free motor and pump option for buyers whose system can accept its power, airflow and connection setup. Verify fit and electrical requirements with the compressor specifications.
Pros
- Oil free design
- Air delivery and maximum pressure are stated
- Applications include tire inflation, spraying and nailing
Cons
- System fit must be confirmed
- Motor and pump are sold as one unit
VEVOR’s 2 HP motor and pump is the complete oil free option in this group. It is rated for 5.2 CFM at 90 PSI and a maximum pressure of 145 PSI, with a stated noise level of 78 dB.
Those figures help you screen for a similar duty level, but they do not confirm that it fits your tank or compressor frame. Check mounting, electrical supply, pressure controls and connection points against the existing system before replacing it.
The stated applications include auto repair, tire inflation, spray painting and woodworking. Choose it when you need an oil free assembly and the rest of your compressor can accept its specifications.
For more choices focused on noise, see our best quiet air compressor pump roundup. The word “quiet” does not replace checking airflow and system compatibility.
VEVOR Air Compressor Pump Head: Best for belt driven twin cylinder systems
- Twin cylinder, single stage pump head
- 3 HP and 5.8 CFM at 90 PSI
- Oil lubricated
- Motor not included
This replacement head is for an oil lubricated belt driven system, so it is not an oil free substitute. Choose it only when the compressor design and lubrication setup match.
Pros
- Twin cylinder configuration
- Air delivery and maximum pressure are stated
- Pump head includes an oil observation mirror
Cons
- Oil lubricated rather than oil free
- Requires a compatible motor and belt setup
VEVOR’s 3 HP pump head is a belt driven, twin cylinder assembly rated for 5.8 CFM at 90 PSI and up to 116 PSI. It is explicitly oil lubricated, and the motor is not included.
That makes it a poor match for a compressor that must deliver oil free air. It may suit a compatible oil lubricated system where the motor, pulley and belt arrangement can be matched.
VEVOR notes that the motor pulley and pump pulley should sit in the same line to reduce vibration. Check the mounting space and drive setup before treating this as a replacement candidate.
For a deeper comparison of twin cylinder designs, see our best twin cylinder air compressor pumps guide. Cylinder count alone does not confirm interchangeability.
I.E.E Campbell Hausfeld Replacement VT4923 3 Hp: Best for listed Campbell Hausfeld models
- Cast iron, single stage pump
- Fits many stated 3 to 3.7 running HP compressor models
- Up to 10.3 SCFM at 90 PSI
- Replaces selected VT part numbers
A model specific cast iron replacement for selected Campbell Hausfeld and Speedaire compressors. It is not identified as oil free, so confirm the original pump’s lubrication type before choosing it.
Pros
- Names replacement part numbers and sample models
- Cast iron construction
- Airflow figure is stated
Cons
- Oil free compatibility is not stated
- Confirm exact model and application
The I.E.E Campbell Hausfeld replacement is a cast iron, single stage pump intended for selected Campbell Hausfeld and Speedaire models. It is described for many compressors in the 3 to 3.7 running HP range, with airflow up to 10.3 SCFM at 90 PSI.
The stated replacement numbers include VT470000KB, VT472200AJ and VT471400AJ. Sample compatible model families are also named, but you should match your exact compressor model and original part before ordering.
This pump is not identified as oil free. If clean, oil free air is essential for your work, confirm the lubrication design with the manufacturer before considering it.
Choose it for the listed replacement applications where cast iron construction and the stated airflow suit your compressor. For an oil free system, prioritize a confirmed oil free replacement instead.
Powermate 040-0354RP Universal Replacement Single Stage Inline: Best for compatible inline twin cylinder compressors
- Single stage, inline twin cylinder pump
- 3.7 RHP
- 11.5 CFM at 90 PSI
- Flywheel and filters included
A higher airflow replacement option for a compatible inline twin cylinder system. Its oil lubrication means it does not meet an oil free replacement requirement.
Pros
- Airflow is stated at 90 PSI
- Flywheel and filters included
- Aluminum head and valve plate help dissipate heat
Cons
- Oil lubricated design
- Universal wording does not replace fit checks
Powermate’s 040-0354RP is a single stage inline twin cylinder pump rated at 11.5 CFM at 90 PSI. It includes a flywheel and filters, and its aluminum head and valve plate are described as helping dissipate heat.
The pump is oil lubricated, so it does not fit a requirement for an oil free pump without changing the compressor’s intended design. The “universal replacement” description still calls for a careful match to the original mounting and drive configuration.
This is a candidate for a compatible oil lubricated compressor that needs more airflow than the smaller options here. Confirm the system’s horsepower and physical setup as well as the airflow target.
NorthStar Air Compressor Pump: Best for demanding cast iron shop systems
- Two stage, three cylinder pump
- 14.9 CFM at 90 PSI
- Full cast iron construction
- Slow RPM operation
A cast iron, higher airflow pump for a compatible demanding shop system. It is not an oil free assembly, and the motor, mounting and drive requirements need to match.
Pros
- Highest stated airflow among these picks
- Three cylinder, two stage design
- Cast iron pump and head
Cons
- Oil free use is not stated
- Heavy pump requires careful compatibility checks
NorthStar’s pump is a two stage, three cylinder design rated for 14.9 CFM at 90 PSI. Its full cast iron construction and slower RPM operation are presented for demanding shop air systems.
This is the highest airflow rating among the six picks, but higher output does not make it a universal replacement. Check the motor, pressure rating, mounting, drive and tank arrangement before choosing it.
The pump is not identified as oil free, so it is not a straightforward replacement for an oil free compressor. Consider it only when the compressor is designed for an oil lubricated pump and the system requirements match.
What should you check before replacing a compressor pump?
Start with the compressor’s model number and the part number on the existing pump. A replacement must match the system’s mounting, drive, motor and pressure needs, while an oil free system also needs a replacement with a confirmed oil free design.
Check these details before buying:
- Lubrication type: Oil free and oil lubricated pumps are different system choices.
- Drive setup: Confirm direct drive or belt drive, pulley size and alignment.
- Airflow and pressure: Compare the replacement’s rating with the compressor and tools.
- Power and mounting: Verify motor needs, bolt pattern, shaft and available space.
- Repair scope: Decide whether a rebuild kit covers the damaged parts or you need a complete pump.
A compressor’s pump or air end may be replaceable separately from its motor, but the parts still need to work together. Read what an air end on a compressor is before ordering a pump head.
Is an oil free pump the right replacement?
An oil free pump is the right choice when the compressor’s original design calls for it or your work requires air without pump oil contamination. Oil free doesn’t mean maintenance free, and it doesn’t guarantee that a replacement assembly will fit your compressor.
If you are replacing the entire compressor instead of repairing it, compare our best oil free air compressor guide. For a pump repair, first check whether the Bonbo kit matches your model or whether the VEVOR complete unit fits your system.
Which oil free air compressor replacement pump should you choose?
Choose the Bonbo kit if your compatible oil free pump needs the included internal parts, and choose VEVOR if you need a complete oil free motor and pump that matches your system. Consider the Campbell Hausfeld, Powermate or NorthStar only for compatible applications where oil lubrication is appropriate.
The best oil free air compressor replacement pump is the one that matches the original system’s model, drive, mounting and airflow needs. Verify those details before ordering, and use an oil free compressor guide if a full-unit replacement makes more sense.

Frequently asked questions
Can I replace an oil free compressor pump with an oil lubricated pump?
Only if the compressor system is designed for that pump and its lubrication method. Oil lubricated replacements such as the VEVOR pump head, Powermate and NorthStar models here are not direct oil free substitutes.
Check the compressor manual and original pump model before selecting a replacement.
Does an oil free compressor always need a new pump?
No. A compatible rebuild kit may address worn internal parts without replacing the full assembly.
The Bonbo kit includes a connecting rod, piston ring, cylinder sleeve and O-rings for named pump models.
Confirm your model and part number before ordering any repair parts.
How do I match a replacement compressor pump?
Match the replacement to the compressor’s model, motor power, drive type, mounting points, pressure and airflow needs. For belt driven systems, check pulley alignment and belt fit as well.
A pump that shares a horsepower label may still have different fittings or mounting dimensions.
What is the difference between a pump head and a compressor motor?
A pump head compresses air, while the motor supplies the force that drives it. Some replacements combine motor and pump, while a pump head may require a compatible motor, pulley and belt.
